高固含量聚丙烯酸乳液的合成与应用陈华,闵峰(巴克曼实验室化工(上海)有限公司,上海201707)摘要:探索合成固含量在50%以上的丙烯酸酯乳液,以甲基丙烯酸甲酯、丙烯酸乙酯、丙烯酸、苯乙烯、丙烯腈,丙烯酸丁酯、丙烯酸异辛酯等为混合单体,以K 12和S-90作为复合乳化剂,以过硫酸铵为引发剂制取聚丙烯酸酯乳液。
通过改变预乳化的水量及控制条件、引发剂的用量、固含量的高低等条件进行多组实验,以探索各影响因素对乳液性能的影响,并筛选其最佳合成条件。
实验还通过在乳液聚合完成之后,通过加入氧化还原体系引发剂,来处理乳液中的残留单体,筛选出各体系下氧化剂和还原剂的最佳用量比。
实验发现采用还原剂FF6M 和70%叔丁基过氧化氢氧化还原体系,当FF6M 占乳液质量的比值约为0.2%,70%叔丁基过氧化氢占乳液质量的比值约为0.2%时,效果最佳。

Triton X-100 产品说明书

TRITON X-100Product Number X-100, T9284, T8787, T8532 Storage Temperature 25°CCAS #: 9002-93-1Synonyms: X-100; TRITON X-1001; Octylphenol ethylene oxide condensate 1Product DescriptionAppearance: Liquid, clear to slightly hazy, colorless to light yellowSpecific gravity: 1.065 at 25°C (approx. 1.07 g/mL)1 Approximate Molecular Weight: 6251;effective molarity =1.7 M for the neat liquid.1UV absorption: λmax = 275 nm (E 1% = 23.9) and 283 nm (E 1% = 19.4) in methanol 2Typical values:Viscosity (Brookfield): 240 cps at 25°C 1Cloud point (1% aqueous solution): 63-69°C 1 Pour point: 7°C 1pH (5% aqueous solution): 6.0 to 8.01 Calculated HLB value: 13.51Critical micelle concentration (CMC): 0.22 to 0.24 mM 3,4The structure of Triton X-100 is very similar to that of Igepal CA-630 (Sigma I3021) and of Nonidet P-40 (no longer commercially available); the names aresometimes reported as synonyms.5 However, Triton X-100 is slightly more hydrophilic than Igepal CA-630. The two are not considered to be functionally interchangeable in most applications.Triton X-100 is a nonionic detergent, 100% active ingredient, which is often used in biochemicalapplications to solubilize proteins. Triton X-100 has no antimicrobial properties.1 It is considered acomparatively mild non-denaturing detergent and isreported in numerous references. It does absorb in the ultraviolet region of the spectrum, so it can interfere with protein quantitation by absorption at A 280nm . A number of polymeric resins have been used to remove X-100 from solution, including Amberlite hydrophobic XAD resins 6 and Rezorian A161 cartridges.3The "Triton X" series of detergents are produced from octylphenol polymerized with ethylene oxide. Thenumber ("-100") relates only indirectly to the number of ethylene oxide units in the structure. X-100 has an"average of 9.5" ethylene oxide units per molecule, with an average molecular weight of 625.1,3 In addition, lower and higher mole adducts will be present in lesser amounts, varying slightly within supplier's standard manufacturing conditions. A by-product formed during the reaction is polyethylene glycol, a homopolymer of ethylene oxide. Acid is also added to the product to neutralize the product after the base catalyzed reaction is completed. No antioxidants are added by Sigma or the manufacturer, but commercial preparations of Triton X-100 have been found to contain peroxides up to 0.22% hydrogen peroxide (H 2O 2) equivalents,7 which may interfere with biological reactions. Sigma offers X-100-PC and X-100R-PC as alternatives. TritonX-100 absorbs in the UV spectrum at approximately the same wavelength as proteins (280 nm). Sigma offers two "reduced", i.e., hydrogenated forms, X-100-RS and X-100R-PC that have significantly lower absorbance in this region.4For lysing cells, typically about 0.1% X-100 solution in water will be sufficient, and even up to 0.5%concentrations will usually not harm most enzymes being isolated.3 Many enzymes remain active in the presence of X-100; for example, Proteinase K, remains active in 1% (w/w) solutions of X-100.8Triton X-100 can be detected in the parts per million range by spectrophotometric measurement of theconcentration of a Triton-ammonium-cobalt-thiocyanate complex.9 Interfering substances in this assay have been discussed.15(OCH 2CH 2)x OHCCH 2C H 3C CH 3CH 3CH 3CH 3x = 9-10For a given application, the choice of a suitable surfactant depends on a number of variables, from its solubility, polarity and micelle size to the mechanism of its action with the target solute. The literature contains numerous articles:10-13!Choice of detergent for solubilization of(erythrocyte) membranes10!Effect of hydrophile-lipophile balance on(cytochrome) membrane solubilization11!Mode of interaction of polyoxyethylene glycol detergents with membrane protein12!General background on surfactants and use in protein purification13Preparation InstructionsTriton X-100 is soluble in all proportions at 25°C in water, benzene, toluene, xylene, trichloroethylene, ethylene glycol, ethyl ether, ethanol, isopropanol, and ethylene dichloride.1 At 10% (v/v) in water, it gives a clear to slightly hazy solution, from clear to slightly yellow in appearance.3Solutions are stable to autoclaving. At certain concentrations the solutions may be cloudy but dispersible above the cloud point; they should clear with stirring upon cooling.14Storage/StabilityTriton X-100 is considered stable for years if stored sealed at room temperature. For special applications, storage under argon or nitrogen at 2-8°C may be preferred. References1. Supplier data (Triton X-100 is a product of UnionCarbide.)2. Wexler, A.S., Anal.

Triton X-100的性质及使用注意事项

Triton X-100的性质及使用注意事项Triton X-100是一种非离子型去垢剂分子式:C14H22O(C2H4O)n用途:Triton X-100是一种比较温和的去垢剂(表面活性剂或称界面活性剂),常作为添加剂使蛋白保持稳定,尤其是膜蛋白。
性质:1. Triton X-100对细菌等微生物没有杀伤作用。
2. Triton X-100在紫外波段下有光吸收(lambda max = 275 nm and 283 nm in methanol),因此,当缓冲液中存在Triton X-100时不能通过测定280nm光吸收来进行蛋白定量。
3. Triton X-100常与CHAPS等zwitterionic 去垢剂一起使用来纯化膜蛋白,使膜蛋白保持其天然构象。
4.Triton X-100可以提高真核细胞细胞膜的通透性,因此在Immunostaining时常使用含0.1%-0.5%Triton X-100的PBS或TBS。
5. Triton X-100非常稳定,密封避光+2 to +8℃条件下可以长期保存。
6.Triton X-100是透明,略显粘稠,稍微发黄的液体。
7. Triton X-100的密度为1.07 g/ml,pH6.0-8.0(5%的溶液)。
8. Triton X-100可以高压灭菌。
9. 用Triton X-100来裂解细胞时,0.1% Triton X-100就足够了,不过,达到0.5%时也没问题。
10. 蛋白酶K在含1% Triton X-100的溶液中依然保持活性。
11. 可以使用Amberlite hydrophobic XAD resins and Rezorian A161 cartridges 来去除Triton X-100 。
