Unit 1 Chemical Industry 化学工业 1.Origins of the Chemical Industry Although the use of chemicals dates back to the ancient civilizations, the evolution of what we know as the modern chemical industry started much more recently. It may be considered to have begun during the Industrial Revolution, about 1800, and developed to provide chemicals roe use by other industries. Examples are alkali for soapmaking, bleaching powder for cotton, and silica and sodium carbonate for glassmaking. It will be noted that these are all inorganic chemicals. The organic chemicals industry started in the 1860s with the exploitation of William Henry Perkin‘s discovery if the first synthetic dyestuff—mauve. At the start of the twentieth century the emphasis on research on the applied aspects of chemistry in Germany had paid off handsomely, and by 1914 had resulted in the German chemical industry having 75% of the world market in chemicals. This was based on the discovery of new dyestuffs plus the development of both the contact process for sulphuric acid and the Haber process for ammonia. The later required a major technological breakthrough that of being able to carry out chemical reactions under conditions of very high pressure for the first time. The experience gained with this was to stand Germany in good stead, particularly with the rapidly increased demand for nitrogen-based compounds (ammonium salts for fertilizers and nitric acid for explosives manufacture) with the outbreak of world warⅠin 1914. This initiated profound changes which continued during the inter-war years (1918-1939). 1.化学工业的起源 尽管化学品的使用可以追溯到古代文明时代,我们所谓的现代化学工业的发展却是非常近代(才开始的)。可以认为它起源于工业革命其间,大约在1800年,并发展成为为其它工业部门提供化学原料的产业。比如制肥皂所用的碱,棉布生产所用的漂白粉,玻璃制造业所用的硅及Na2CO3. 我们会注意到所有这些都是无机物。有机化学工业的开始是在十九世纪六十年代以William Henry Perkin 发现第一种合成染料—苯胺紫并加以开发利用为标志的。20世纪初,德国花费大量资金用于实用化学方面的重点研究,到1914年,德国的化学工业在世界化学产品市场上占有75%的份额。这要归因于新染料的发现以及硫酸的接触法生产和氨的哈伯生产工艺的发展。而后者需要较大的技术突破使得化学反应第一次可以在非常高的压力条件下进行。这方面所取得的成绩对德国很有帮助。特别是由于1914年第一次世界大仗的爆发,对以氮为基础的化合物的需求飞速增长。这种深刻的改变一直持续到战后(1918-1939)。 date bake to/from: 回溯到 dated: 过时的,陈旧的 stand sb. in good stead: 对。。。很有帮助

有机论文

浅谈亲核重排反应及它们的应用 阮赛 摘要:分子重排反应在有机化学中一般都归入反应机理的内容之列。由于分子重排反应在理论上和实际应用上都有它特殊的意义, 所以 人们对它的研究和认识做了大量的工作。通过对分子重排反应的讨论, 可以加深我们对有机化学知识的认识。 概念:分子重排反应(molecularrearrangement) 。有机化学反应类型之一。一些有机化学反应,有机物在试剂、加热、或其他因素的影响下,分子中某些原子(或基团)发生转移,分子碳架或者官能团的位置发生改变,甚至环的大小也发生变化,这样一些反应称为分子重排反应。 一、重排反应类型 分子重排是大量存在的,为了研究方便,也要对其进行分类。通常有下面几种分类方法。 (一)按分子内重排及分子间的重排分类 一.分子内重排 发生分子内重排反应时,基团的迁移仅发生在分子的内部。根据其反应机理,可分为分子内亲电重排和分子内亲核重排。

1. 分子内亲核重排 分子内发生在临近两个原子间的基团迁移,多数情况下属于分子内亲核重排。例如:辛戊基溴在乙醇中的分解; 2. 分子内亲电重排 分子内亲电重排反应多发生在苯环上。常见的有联苯胺从排、N-取代苯胺的重排和羟基的迁移等。 氢化偶氮苯在酸的作用下,可发生重排反应生成联苯胺。N-取代苯胺在酸性条件下,可发生取代基从氮原子上迁移到氮原子的邻位、对位上的反应。例如:亚硝基的迁移,它也是亲电性的重排反应。 苯基羟胺在稀硫酸作用下,可发生OH-的迁移,即OH-作为亲核质点从支链迁移到芳环上,生成氨基酚。 二.分子间的重排 分间的重排可看作是几个基本过程的组合。例如,N-氯代乙酰苯在盐酸的作用下发生重排:先是发生置换反应产生分子氯,然后,氯与乙酰苯胺进行亲电取代反应得到产物。 (二)、按反应历程分类 根据迁移基团的亲核、亲电或是自由基的性质,重排反应可分为亲核重排、亲电重排和自由基重排。亲核重排是迁移基团带着一对电子迁移到缺电子的迁移终点。用“Z”表示迁移基团,“B”为迁移终点,亲核重排可用通式表示如下: 缺电子中心B可以是碳正离子、碳烯、氮烯、也可以是缺电子的氧原子。由于产生不稳定正性中心的方法很多,所以亲核重排反应的类型也是最多的。重排过程中迁移基团始终未离开分子,往往发生邻基参与,形成类似环丙烷正离子的二电子三中心体系,是一个芳香过渡态,体系能量较低,容易生成,这也是亲核重排反应多的原因之一。

丹宁改性絮凝剂处理城市污水 J.Beltrán-heredia,J.ánche z-Martin 埃斯特雷马杜拉大学化学工程系和物理化学系,德埃娃儿,S / N 06071,巴达霍斯,西班牙 摘要 一种新的以丹宁为主要成分的混凝剂和絮凝剂已经过测试用以处理城市污水。TANFLOC 证实了其在浊度的去除上的高效性(接近100%,取决于剂量),并且近50%的BOD5和COD 被去除,表明TANFLOC是合适的凝集剂,效力可与明矾相媲美。混凝絮凝剂过程不依赖于温度,发现最佳搅拌速度和时间为40转/每分钟和30分钟。多酚含量不显著增加,30%的阴离子表面活性剂被去除。沉淀过程似乎是一种絮凝分离,所以污泥体积指数和它随絮凝剂剂量的改变可以确定。证明TANFLOC是相当有效的可用于污水处理的混凝絮凝剂。 关键词: 基于丹宁的絮凝剂城市污水絮凝天然混凝剂 1.简介 人类活动是废物的来源。特别是在城市定居点,来自家庭和工业的废水可能是危险有害的产品[ 1 ],需要适当的处理,以避免对环境[ 2 ]和健康的影响[ 3,4 ]。2006年12月4日联合国大会通过决议宣布2008为国际卫生年。无效的卫生基础设施促使每年220万人死于腹泻,主要在3岁以下儿童,600万人因沙眼失明,两亿人感染血吸虫病,只是为了给出一些数据[ 5 ]。显然,他们中的大多数都是在发展中国家,所以谈及城市污水,必须研究适当的技术来拓宽可能的处理技术种类。 在这个意义上,许多类型的水处理被使用。他们之间的分歧在于经济和技术特点上。了摆脱危险的污染[ 6 ],一些令人关注的论文已经发表的关于城市污水处理的几种天然的替代方法,包括绿色过滤器、化学初步分离、紫外消毒[ 7 ]和多级程序[ 8 ]。 几个以前的文件指出了城市污水管理[9,10]的重要性。这种类型的废物已成为社会研究的目标,因为它涉及到几个方面,都与社会结构和社会组织[11 ]相关。根据这一维度,必须认识到废水管理作为发展中国家的一种社会变化的因素,事关污水处理和生产之间的平衡,是非常重要的,一方面,人类要发展,另一方面,显而易见。 对水处理其它程序的研究一直是这和其他文件的范围。几年来,研究者关注的是发展中国家间的合作,他们正在致力于水处理的替代过程,主要考虑可持续发展,社会承受能力和可行性等理念。在这个意义上,自然混凝絮凝剂这一广为传播,易于操作的资源即使是非专业人员也不难操作。有一些例子,如辣木[ 14 ]和仙人掌榕[ 15 ]。丹宁可能是一个新的混凝剂和絮凝剂。 一些开拓者已经研究了丹宁水处理能力。 ?zacar和sengil [ 16 ]:从瓦罗NIA获得的丹宁,从土耳其的autoctonous树的果壳中获得丹宁,并用于他们的–污水混凝絮凝过程。他们表明,丹宁有很好的效果,结合Al2(SO4)3可进一步提高污泥去除率。 詹和赵[ 17 ]试着用丹宁为主要成分的凝胶作为吸收剂除去水中的铝,丹宁凝胶改进了金属去除过程,一定意义上也可参照Nakano等人的[ 18 ],Kim 和Nakano[ 19 ]。 ?zacar和sengil [ 20 ]加强以前的文章给出了关于三卤甲烷的形成和其他不良化合物特殊的数据,以及处理后的水质安全。他们始终使用丹宁与Al2(SO4)3的组合。 帕尔马等人将丹宁从辐射松的树皮为原位提取,用于重金属去除中聚合固体。树皮本

不同条件下Friedel-Crafts酰基化反应的研究 摘要:本文介绍了沸石等作为Friedel-Crafts反应催化剂时的情况,综述了其研究 进展及应用。 关键词:Friedel-Crafts反应离子液体沸石 引言 Friedel-Crafts酰基化反应是酰卤等化合物在Lewis酸催化下,对芳香族化合物的酰化反 应。研究发现是酰基化反应的高效催化剂,价廉易得,在一般工业生产中应用较多。 近年来一些离子液体催化剂,即可以保持强Lewis酸性,又可在常温下催化酰化反应,抑制高温下裂解、歧化和降解等副反应发生。此外,沸石分子筛也是一种比较理想的Friedel-Crafts 酰基化反应催化剂。 我们小组通过翻阅资料,查找相关文献,综合介绍了以上不同条件下Friedel-Crafts酰基化反应的研究进展及应用。 正文 1.酰基化催化剂 是最常用的酰基化催化剂,它能在芳香族化合物、含苯环聚合物上引入酰基, 反应需在溶剂中进行。 1.1苯型芳香族化合物的酰化 酰基化通常用下式表示。 由于产物芳酮和有强的络合作用,因此通常需加入大量的水将水解掉, 才能得到纯净的芳酮产物。 当芳环上有强供电基团时,反应容易进行。当芳香族化合物含具有孤对电子的推电子基团时,更易与其络合,在这种情况下,需要把具有供电基团的有机溶剂和 络合使用,如。芳环上有吸电基团时,酰化反应难于进行。 如在间位有卤素取代基时,一般需要大量的催化剂。 1.2含苯环聚合物的酰基化 含有苯基的聚合物,如聚苯乙烯,通过酰基化可以增强原聚合物的粘附力、物理机械性能、强性和光敏感性。例如,用催化马来酸酐化聚苯乙烯可以得到一类具有新的性能的聚苯乙烯。

有机化学高档次杂志投稿之我见

认识一个朋友,他对有机化学投稿十分有经验,最近有幸邀请到他谈了谈对有机化学高档次期刊投稿过程中的一些看法和意见,十分的给力,希望能对小木虫上学有机化学乃至化学的同仁们起到一定帮助。再次感谢这位友人的热情应邀。 在小木虫潜水多年,也获益非浅。抽空写了如下的个人感受,希望对大家有所帮助。 曾经见过的JACS和ANGEW CHEM投稿不下50 篇.其他化学2区的文章投稿可能就更多了.总而言之,看过的审稿意见不下100 篇。下面就我的所见,总结一下我对有机化学投稿的一些个人看法。主要是JACS, ORG LETT。只是个人的感受,如有失偏颇,敬请原谅。其次文章写的比较流水,大家轻拍。 虽然主题是有机化学杂志投稿,但我认为对其他专业的期刊投稿也都很有借鉴意义。 1. JACS和ANGEW CHEM比较 许多人可能都知道,JACS (IF=是纯化学期刊中的老大(CNS除外).虽然影响因子(IF)没有ANGEW CHEM (IF=12)高,但由于ANGEW CHEM只有通讯无全文(一般通讯的引用次数会比全文的期刊高:如ORG LETT比JOC高; ANGEW CHEM比其全文的CHEM. EUR. J.高,等等 ),还有ANGEW CHEM有REVIEW ARTICL (REVIEW的引用次数一般都很高,如CHEM. REVIEW, ACC. CHEM. RES., CHEM. SOC. REV. ), 还有ANGEW CHEM有德文版本(会有双重引用). 可能很多人认为JACS比ANGEW CHEM难中.但我不完全这么认为.毕竟文章能否接收和很多因素有关.虽然的确有一些JACS拒掉的文章改投ANGEW CHEM却接受了(我见过4篇左右).但我也有见过很多投JACS没有中的,投ANGEW CHEM也没有中.而一些投ANGEW CHEM没有中的,改投JACS却反而被接收了(我见过的3篇).但总体来说,可能ANGEW CHEM中的发表的有机化学的文章比例比JACS中的比例高,所以可能ANGEW CHEM接收可能还是会比JACS简单一点. 2. JACS很难投中 JACS很难投中,他对工作的新颖性要求很高.最近几年由于JACS偏重材料和生物化学,所以有机的想发JACS, 难度就更大了. 现在JACS每年收到的稿件太多,且逐年增长,所以他们肯定会尽量来拒你的稿子,拒稿率高于80%.很多很优秀的有机合成工作最后只能在ORG LETT, CHEM COMMUN, CHEM EUR J, JOC, ADV. SYNTH. CATAL.等杂志上发表. 我有一个朋友,他是负责HIGHLIGHT化学期刊上的优秀的研究工作的.有一次他就说:ORG LETT上有些工作很好,但由于有些审稿人员太STUPID,所以JACS被拒了,最后只能无奈改投并发表在ORG LETT. 一般我们看到发在JACS上的有机合成工作,大部分都集中于不对称催化和过渡金属催化的有机反应两个领域. 所有如果能向这两个方向靠的话,JACS可能会容易发一些.

有机化学小论文

装修材料中的有毒有机化合物 姓名:XXX 班级:XXX 学号:XXX 摘要: 有很多悲剧是在人们认为十分安全的地方——新装修的家中发生了。究其原因是因为装修的材料里有许多有毒的有机化合物,它们从材料中挥发出来,散入空气,不知不觉中对人体造成了危害。因此,正确地认识这些有机化合物,并做好预防措施对于避免更多的悲剧的发生有着极为重要的意义。本文就装修材料中常见的有毒有机化合物进行了总结和讨论。 关键词: 装修材料有毒有机化合物措施 正文: 引言: 我对于装修材料中有毒有机化合物的危害最初了解始于我一个老师,她举例曾有一个孩子因为在搬进新房后脑受了影响,失去了正常的智力。这给了我极大的震撼。高中时我们在课本上学习了一些相关的有毒有机化合物,然而并不深入。为了更好的了解它们,我查阅了相关资料,对这些化合物有了更深层次的认识。一、装修材料中的有毒有机化合物分类 有毒装修材料中的有害物质可以分为四大类:刺激性物质、过敏性物质、致癌性物质、生殖毒性物质 1、刺激性物质:对于呼吸道、眼睛、手、皮肤等具有刺激性,会引起呼吸困难,眼睛刺痛,皮肤出现红斑等症状。 2、过敏性物质:会刺激机体产生过敏反应。如最常用的家具漆是聚氨酯漆主要含2-异氢酸甲醛酯,具有典型的致敏作用,会引起支气管炎或哮喘。 3、致癌性物质:有些装修材料会释放致癌物质或放射性物质,对于长期接触的人会诱发癌变。如接触甲醛达到一定量后,有可能引起鼻腔癌、咽喉癌、肺癌等。 4、生殖毒性物质:对生殖功能产生影响,可令男性精子数量递减,精子存活率和活力降低,使怀孕妇女产下畸胎儿。 以上四类有机化合物造成人体功能的紊乱,免疫力下降,从而给人们的健康造成危害。 二、装修材料中几种主要的有毒有机化合物 1、甲醛 毒源:家具和橱柜中的胶合板、密度纤维板、刨花板等在遇热、潮湿时甲醛就会释放出来。另外,不合格的涂料和乳胶漆、粘合剂、织物、地毯等等 都是甲醛释放的来源。 主要危害:甲醛和苯是导致白血病的两大重要污染物。长期接触低剂量甲醛可引起慢性呼吸道疾病、女性呼吸道紊乱、妊娠综合症,引起新生儿体质 降低、染色体异常,甚至引起鼻咽癌。高浓度甲醛对神经系统、免疫 系统、肝脏都有毒害。甲醛还有致畸、致癌作用。长期接触甲醛的人, 可能引起鼻腔、口腔、鼻咽、咽喉皮肤和消化道的癌症。 甲醛是一种原生毒物,在空气中能对眼、鼻、喉、皮肤产生明显的 刺激作用,空气中甲醛低于0.2mg/m3时,刺激作用微轻;超过3.6mg/m3 时,刺激增强;4.8mg/m3-6mg/m3接触30分钟,引起流泪和不适;

自由Cu点击化学 在19世纪后期,Michael 第一个发现了叠氮化合物和炔烃的环加成反应生成三唑化合物,在20世纪中期,Hulsgen花了大量的时间分析环加成反应的机理,产生了物理有机化学科目分支,可以把这个反应转变成正交反应。与斯陶丁格连接反应一样的是,环加成反应最大的不足之处,用传统未活化的炔烃反应,反应的动力学很弱,需要很高的温度和压力, Hulsgen反应确实需要高温高压,但是这远远超过了生物系统所承受的极限。 在21世纪初期,Sharpless and Meldal注意到了Huisgen环加成反应可以作为一种得到一对选择性高功能分子,他们独立发表了通过Cu作为催化剂可以大大提高末端炔烃的反应速率。今天,这个反应被作为Cu点击化学一个典型反应,已经被使用在很多的领域,包括生物化学,它也是正交反应,主要不好的是Cu 具有生物毒性。已经有几个实验室致力于减少Cu的毒性,或者经过配基优化增加催化剂的相关性,最近已经成功实现了叠氮化合物与末端炔烃的反应在活生物体中反应。 我们一直追求避免使用金属催化剂,希望通过采矿业的经典机械理论发现一种对生物友好的叠氮化合物与炔烃的反应。在1961年Wittig and Krebs报道了环辛炔是一种最不稳定的炔烃,和苯基叠氮化合物反应像爆炸一样。我们可以推断出在环辛炔与环加成反应中有18cal/mol的热量释放。 通过一个假定的Cu自由点击化学,我们可以合成一些可以作为生物探针功能的环辛炔,在图8A中的OCT化合物可以与生物素连接进行生物标记的研究。

线性炔烃本质上不会与叠氮化合物反应在生理温度的条件下。但是,OCT-biotion 能很容易与标记了多糖的叠氮化合物反应在细胞的溶解产物中。在图8B C中,化合物没有表现出明显的毒性,与Cu作为催化剂完全相反,然而,在模型反应中的二阶速率常数0.0024/ms,OCT没有比斯陶丁格反应更快,并且化合物水溶性也有限。 我们着手通过分子改造加快反应速率和提高物理性能为了应用于活体成像。“aryl-lessoctyne” 13 (ALO)有很好的水溶性,但是反应动力学性能与OCT差不多。通过在丙炔位置加入吸电子的F原子得到一氟化环辛炔MOFO(14)反应速
