溶劑精製-利用溶劑作為于段(利用溶劑方式? ) ,有選擇性地萃取不需要的組份,進而提高基礎油質量的一種精製工藝。A novel aqueous two - phase system can be formed by the mixtures of a polymer and cationicanionic surfactants. such a system can be used as a partitioning system of proteins. in this work, we investigated the formation, phase behavior and protein partitioning in aqueous two - phase systems formed by dodecyltriethylammonium bromide / sodium dodecylsulfate / peg and dodecyltriethylammonium bromide / sodium dodecylsulfate / dextran. the ligands with affinity were attached to the polymers and the affinity partitioning of proteins was investigated. it was shown that the surfactants and polymers are enriched in different phases of aqueous two - phase systems. phase separation are promoted by increasing temperature and adding inorganic salts. different proteins are partitioned in different phases. the selectivity of protein partitioning is increased by adding ligands with affinity
報道了由正負離子表面活性劑與高聚物混合溶液形成的一種可用於蛋白質的分離及分析的新型雙水相萃取體系.研究了正負離子表面活性劑(溴化十二烷基三乙銨/十二烷基硫酸鈉)分別與葡聚糖和聚乙二醇混合雙水相體系的形成規律、相行為及牛血清蛋白和溶菌酶在雙水相體系中的分配.通過在高聚物分子中接上親和配基,研究蛋白質在雙水相體系中的親和分配.結果表明,在該體系中,表面活性劑與高聚物分別富集於不同相中.升高溫度及加入無機鹽均可促進雙水相體系的形成,不同蛋白質可分配于不同的相中.親和配基的引入極大地增強了蛋白質分配的選擇性Water quality - physical, chemical and biochemical methods - determination of selected phenoxyalkanoic herbicides, including bentazones and hydroxybenzonitriles by gas chromatography and mass spectrometry after solid phase extraction and derivitization
水質.物理化學和生物化學法.固相萃取和衍生化作用后氣相色譜質譜法測定包括苯達松和羥基苯甲晴在內的選擇性苯氧烷類鋤草劑The experimental data are correlated by using uniquac and nrtl models, and the model parameters of this system have been obtained respectively, and the selectivity coefficients of the extracted solvent to solutes were calculated
實驗數據用uniquac和nrtl模型進行關聯,分別得到了三元體系的模型參數,並求得了萃取溶劑對溶質的選擇性系數。In addition, the extractive distillation process with mixed solvents have a better performance and a wider use compared with that with single solvent in the same condition, and it can not only overcome conflict of single solvent ' s selectivity and solubility, but also not increase the complexity of original technology
另外,混合溶劑萃取精餾過程與簡單溶劑萃取精餾過程相比,克服了簡單萃取劑自身選擇性與溶解性之間的矛盾,提升了萃取精餾工藝的分離效果及使用范圍,並且沒有增加原有工藝過程的復雜性。分享友人
