After solvent extraction and drying, the pure unsaponifiables are obtained in the form of a waxy solid. This waxy solid is then redissolved in untreated shea butter to increase the unsaponifiable content and thus lead to the unsaponifiable shea butter concentrate. Used in cosmetics at levels of up to 2%,it provides excellent protection against sunlight and skin dryness.Another example is the extract of the kola nut, known for its anti-irritant properties. As available in the market, it has an objectionable color and odor . At Estee Lauder, we analyzed and separated its constituents, identified the individual components with anti-irritant properties, and recombined them in the most effective ratio. In the process , objectionable color and odor were removed and possible allergens（过敏原）eliminated. All this indicates that cosmetics formulated with plant extracts today can be more effective and , at the same time, more elegant than 10 or 20 years ago.四、Translate the following paragraph into Chinese（本大题共1个小题，共25分）采用一种简单、可靠并且有效的气相色谱法，来同时测定草药鱼腥草与鱼腥草注射液中8种活性组分的含量。

(5 points) Fill in the blanks in the following paragraph with the appropriate words or phrases listed at the end of paragraph: The rules that govern the naming of chemical compounds are known collectively as chemical ________________. In a simple way, the name of a cation consists of the name of the element, the _____________on the ion as a Roman numeral in parenthesis, and the word “ion”. The name of a monatomic _______________ (e.g., Cl-) consists of the name of the element with the ending“ide”, followed by the word “ion”. A binary compound is one containing atoms or ions of only two ________________. Salts are _________________ formed between cations and anions of acids. For binary molecular compounds, prefixes are used to indicate the number of each element present.anion elements nomenclature ionic compounds chargeVI. (5 points) Fill in the blanks in the following paragraph with the appropriate words or phrases listed as follows:The geometry around the C=C double bond in an __________ plays an important role in the chemistry of these compounds. The presence of the bond restricts rotation around a C=C double bond. There is no way to rotate one end of this bond relative to the other without breaking the bond. Because the _____________ is relatively strong (270 kJ/mol), rotation around the C=C double bond cannot occur at room temperature. Alkenes therefore form stereoisomers that differ in the way substituents are arranged around the C=C double bond. The ____________ in which similar substituents are on the same side of the double bond is called cis; whereas that with similar substituents are across from each other, is called trans. The cis isomer of 2-butene, for example, has both _____________ groups on the same side of the double bond. In the trans isomer the CH3 groups are on the ______________ sides of the double bond.opposite alkene methyl bond energy isomerVII. (10 points) Fill in the blanks in the following with the appropriate words or phrases listed at the end of the paragraph: So far, we have built a small repertoire of reactions that can be used to convert one functional group to another. We have briefly discussed converting alkenes to alkanes; alkanes to alkyl halides; alkyl halides to alcohols; alcohols to ethers, aldehydes, orketones; and aldehydes to carboxylic acids. We have also shown how carboxylic acids can be converted into esters and amides. We have yet to encounter a reaction, however, that addresses a basic question: How do we make C-C bonds? One answer resulted from the work that Francois A.Grignard started as part of his Ph.D. research at the turn of the last century.Grignard noted that alkyl ____________ react with magnesium metal in diethyl ether to form compounds that contain a metal-carbon bond. Methyl bromide, for example, forms methylmagnesium bromide.Et2OCH3Br + Mg →CH3MgBrBecause carbon is considerably more _______________ than magnesium, the metal-carbon bond in this compound has a significant amount of ionic character. Grignard reagents such as CH3MgBr are best thought of as hybrids of ionic and ___________ Lewis structures.CH3-Mg-Br ?[CH3-] [Mg2+] [Br-]Grignard reagents are our first source of carbanions (literally, "anions of carbon"). The Lewis structure of the CH3- ion suggests that carbanions can be Lewis bases, or electron-pair _____________. Grignard reagents such as methylmagnesium bromide are therefore sources of a nucleophile that can attack the + end of the C=O double bond in aldehydes and ketones. Thus the most important aspect of the chemistry of Grignard reagents is the ease with which this reaction allows us to couple alkyl chains. Isopropylmagnesium bromide, for example, can be used to graft an isopropyl group onto the ____________ chain of an appropriate ketone.electronegative hydrocarbon covalent donors halidesVIII. (10 points) Fill in the blanks in the following with the appropriate words or phrases listed at the end of the paragraphs: Why do some solids dissolve in water? The sugar we use to sweeten coffee or tea is a molecular solid, in which the individual molecules are held together by relatively weak ________________________. When sugar dissolves in water, the weak bonds between the individual sucrose molecules are broken, and these C12H22O11 molecules are released into ________________. It takes energy to break the bonds between the C12H22O11 molecules in sucrose. It also takes energy to break the hydrogen bonds in water that must be disrupted to insert one of these sucrose molecules into solution. Sugar dissolves in water because energy is give n off when the slightly polar sucrose molecules form intermolecular bonds with the polar water molecules. The weak bonds that form between the solute and the solvent compensate for the energy needed to disrupt the structure of both the pure solute and the solvent. In the case of sugar and water, this process works so well that up to 1800 grams of sucrose can dissolve in a liter of water.Ionic solids(or salts) contain positive and negative ions, which are held together by the strong force of __________________ between particles with opposite charges. When one of these solids dissolves in water, the ions that form the solid are released into solution, where they become associated with the ___________________solvent molecules.H2ONaCl(s) →Na+(aq) + Cl-(aq)We can generally assume that salts ________________ into their ions when they dissolve in water. Ionic compounds dissolve in water if the energy given off when the ions interact with watermolecules compensates for the energy needed to break the ionic bonds in the solid and the energy required to separate the water molecules so that the ions can be inserted into solution.dissociate intermolecular forces attraction polar solutionIX. (10 points) Fill in the blanks in the following with the appropriate words or phrases listed at the end of the paragraphs:A soap bubble is simply a very thin sheet of water sandwiched between two layers of soap molecules, also called _____________________. These molecules are called amphiphilic. This means that part of this molecule is attracted to water, which is hydrophilic, and another part is repelled from water, which is _____________________.When such a molecule is put in water, as many as possible will crowd to the surface, so that the heads can stay in the water, while the tails stick out into the ___________. This is why soap-like molecules are called surfactants, since they mostly affect the _________ of water. It is these molecules that make soap bubbles stable.Some bubbles result from gas being trapped in solution, such as CO2 in soda and champagne, or N2 in the blood of deep sea divers. Much study goes into understanding bubbles dissolved in gases, as well as how the formation of large surfaces from surfactants used to construct bubbles are affected by different factors, e.g., temperature, surface __________ , nucleation sites, etc..air, pressure, hydrophobic, surface, surfactant molecules。

These are called semipermeable membranes. Semipermeable membranes that allow passage of solvent molecules but do not allow passage of solute molecules or ions are called osmotic membranes. If a NaCl solution is separated from pure water by an osmotic membrane, H 2O molecules spontaneously penetrate the membrane from both directions; however, passage across the membrane from the pure water side is faster than passage across the membrane from the solution side. The net result is exactly like that illustrated already previously and involves a net transfer of H 2O from the pure water side of the membrane to the solution side of the membrane. The passage of solvent molecules from a region with little or no dissolved solute, through an osmotic membrane, to a region with more dissolved solute is called osmosis.Passage two: As in ionic bonding and covalent bonding, outer shell electrons are responsible foe bonding between metal atoms. However, it is unreasonable to assume that ionic bonds occur between metal atoms since all the atoms are alike and no single atom would give up electrons to another atom. Covalent bonding between metal atoms is almost as unreasonable because not enough outer shell electrons are available for as many shared-pair bonds as each metal atom seems to form. Instead, a metallic lattice consists of a regular array of positive ions immersed in a cloud of highly mobile outer shell electrons. Metals have relatively low ionization energies or relatively loose holds on their outer shell electrons. These electrons are free to move throughout the metallic lattice. Metallic bonding results from attraction between the positive ions and the cloud of negative electrons. Such attractive forces are weaker than ionic or covalent bonding forces. Thus, many metals are soft and fairly low melting. Potassium is soft enough to be cut with a knife and melt at 68.7℃. On the other hand, some of the transition metals, where significant covalent character is superimposed on the metallic lattice, are hard and high melting.Tungsten is very hard and melts at about 3410℃Passage three: Major branches of Chemistry .The body of knowledge about chemicals and chemical reactions is so vast that for convenience chemists have divided the study of chemistry into several major branches: l. Analytical chemistry: The study of what types of elements and compounds are present in a sample of matter — called qualitative analysis — and how much of each element and compound is present in a sample of matter — called quantitative analysis.2. Physical chemistry: The study of the scientific laws and theories that attempt to describe and explain the structure of matter, the chemical bonds that hold matter together, the changes that matter undergoes, and the energy involved in these changes.3. Organic chemistry: The study of the properties and reactions of hydrocarbons, compounds containing only the elements carbon and hydrogen, and other compounds derived from hydrocarbons that contain one or more other elements such as oxygen, nitrogen, sulfur, phosphorus, and chlorine. About4.9 million of the 5 million officially identified compounds are classified as organic compounds—explaining why an entire branch of chemistry is devoted to studying these compounds4. Inorganic chemistry: The study of all elements and the properties and reactions of the compounds not classified as organic compounds.5. Biochemistry: The study of the properties and reactions of compounds found in living organisms and those that are important to living organisms.These branches make it easier to study chemistry. Real chemistry, however, almost always involves a blend of information and ideas from most — if not all — of these branches. This book is concerned with general chemistry — a survey and introduction to all the major branches of chemistry except biochemistry.2020-2021《化学专业英语》期末课程考试试卷答案PartⅠ、Choice（28×1.5=42 points）（按顺序填入答案）1—5题 ADCAC 6—10题 ABBCB11—15题 CABAC 16—20题 CACDC 21—25题 CACBA 26—28题 CBA Part Ⅱ1.(1) Magnesium hydroxide(2) Nitrogen reacts with hydrogen to form ammonia at high temperatureand pressure with the presence of a catalyst.(3) Log x to the base n.(4) The nth root of x.(5) Calcium carbonate when heated produces calcium oxide and carbondioxide.(6) X to the minus eighth (power).(7) Five over one hundred and twenty_three.(8) The ratio of two to three.(9) Plus and minus.(10) One (a) hundred degrees Centigrade.2. （1）醇（2）量（3）分析纯（4）装置（5）含有。

2：（2-amino-5-hydroxybenzaldehyde）5.Translate the following paragraphs into Chinese:
\
(1)Pick the size of your separatory (sep.) funnel. You will usually use 125 or 250-mL,
large scale reactions (1–10 g) can require 500-mL or 1-L sizes. Remember that your sep. funnel will contain the solvent and wash liquid which must be thoroughly mixed. (5% for the answer)
参考答案：挑选出你要的分液漏斗的大小。

你通常会使用125毫升或者250毫升的分液漏斗，对于大规模的反应（1-10克）你需要使用500毫升或1 L的分液漏斗。

记住你的分液漏斗将含有溶剂和洗涤液，必需予以彻底的混合。

(2)Dilute the crude reaction mixture with your solvent of choice and transfer to your
chosen sep. funnel. Large amounts of material require large amounts of solvent.
Normal reactions (50-500 mg of product) can be diluted with between 25–100 mL of solvent. (5% for the answer)
参考答案：用你所选用的溶剂稀释反应粗产物的混合物，并且转移到你选择的分液漏斗中。

大量的材料需要大量的溶剂。

正常的反应（50-500毫克的产品）能用25-100毫升溶剂稀释。

、
(3)Dry the organic layer. After removing your solution from the aqueous phase, a
drying agent is added to remove all traces of water. This is usually MgSO4, more effective and faster, but slightly acidic; or Na2SO4, less effective and slower, but neutral. These compounds bind to any water remaining in the organic solution, forming clumps when they react. A decent amount of drying agent should be added, but as long as some solid is not clumped, no more needs to be added. (6% for the answer)
参考答案：干燥的有机层：从水相中取出溶液后，干燥剂的加入是为了除去遗留下来的水份。

通常使用硫酸镁作干燥剂，因为它非常有效而且吸水很快，但是略带酸性，或者也可以用硫酸钠，只是效益比较和速度比较慢，但是中性的。

这些化合物会和有机溶液中的水相结合，当它们发生反应时就会形成团块。

应该有足够量的干燥剂被加入，但是只要一些固体不会形成团块，就不需要再加入更多的干燥剂。

(4)Distillation is an extremely useful technique that is used to purify reagents and
separate crude product mixtures. There are two varieties of distillation atmospheric pressure and reduced pressure. (4% for the answer)
(5)~
(6)
参考答案：蒸馏是一个非常有用的技术，用于分离纯化试剂和粗产品的混合物。

一般有两种蒸馏方法：常压蒸馏和减压蒸馏

Title:Heterogeneous Baeyer-Villiger oxidation of ketones using hydrogen peroxide as oxidant catalyzed by aminomethyl polystyrene resin-supported tin complex.
#
Abstract: An aminomethyl polystyrene resin supported tin complex (PS-Sn) catalyst was prepared by a simple procedure and found to be an active and selective catalyst for the Baeyer-Villiger (BV) oxidation of cyclic and acyclic ketones including 2-adamantanone, 2-methylcyclohexanone, cyclohexanone, 4-tert-butylcyclohexanone, 4-methylcyclohexanone, 3-methyl-2-pentanone, 4-methyl-2-pentanone, and cyclopentanone using 30% hydrogen peroxide as oxidant. This polymer-supported tin complex acts as an efficient and stable heterogeneous catalyst for the Baeyer-Villiger oxidation of ketones by 30% hydrogen peroxide. The catalyst can be prepared in large scale in a simple manner and can be recycled.
(1) What oxidant was used in the BV oxidation (3% for the answer)
(2) What do the words “acyclic” and “heterogeneous” mean (3% for the answer)
(3) What are the advantages of the catalyst (4% for the answer)
Heterogeneous 非均相的acyclic 无环的catalyst 催化剂
