  脂肪酸烷基酯作为酶催化合成甲基丙烯酸烷基酯和聚苯乙烯-甲基丙烯酸烷基酯共聚物的原料，用作柴油燃料的冷流改进剂

  摘要：

  使用南极假丝酵母进行脂肪酸甲酯（FAME）与甲基丙烯酸羟乙酯（HEMA）的酶促酯交换反应脂肪酶B固定在多孔聚甲基丙烯酸酯树脂中。FAME与HEMA进行酯交换反应的酶活性取决于溶剂的极性，在甲苯（非极性）中获得最高收率。1：4（对于月桂酸甲酯：HEMA）和1：2（对于油酸甲酯：HEMA）的摩尔比最有利于酯交换反应的收率。反应条件（在60°C / 24 h时），月桂酸甲酯与HEMA的酶浓度为5％（w / w），油酸甲酯与HEMA的酶浓度为2％（w / w），导致最终收率最高。在这些条件下，月桂酸甲酯与HEMA，油酸甲酯与HEMA进行酯交换的最大收率分别为97±5.4％和91±4.7％。FAME与HEMA进行十批酯交换后，酶活性保持在88±2.6％和76±2.3％的水平，分别与其初始活动进行比较。另外，通过HEMA-LMA（或HEMA-OMA）和苯乙烯的自由基聚合反应合成了甲基丙烯酸烷基酯/苯乙烯共聚物。制备的共聚物的平均分子量为2

  In lithographic inks containing colorant, binder resin and reactive diluent, the diluent comprises oxidatively curable ester prepared by reaction of drying oil fatty acid with hydroxyl-containing, addition polymerizable compounds, such as reaction product of polyol with addition polymerizable acid, hydroxyalkyl ester of such acid, hydroxyalkyl vinyl sulfide or hydroxyalkyl vinyl ether. The curable ester may also be prepared by reaction of addition polymerizable acid with hydroxyl-containing reaction product of polyol with drying oil fatty acid. Transesterifiable esters can be used instead of the acids. Preferred drying oil acids are derived from tung oil, linseed oil, safflower oil, soybean oil or dehydrated castor oil. The curable ester preferably comprises acryloxy alkyl or methacryloxy alkyl drying oil fatty acid ester.
