阳离子交换树脂催化甲基丙烯酸十二醇酯的合成研究

Study on the preparation of methylacrylic dodecyl alcohol esters in the catalysis of cationic exchange resin

介绍了以新型阳离子交换树脂为催化剂,合成甲基丙烯酸十二醇酯的合成工艺过程.实验结果表明,最佳工艺条件是十二醇与甲基丙烯酸的摩尔比为1.25:1;催化剂阳离子交换树脂用量为1.5 g,溶剂二甲苯用量为20 mL.此工艺条件下,酯化收率达到96.6％.

The preparation of methylacrylic dodecyl alcohol esters in the catalysis of cationic exchange resin is introduced. The tests show that when the molar ratio of dodecanol to methylacrylic acid is 1.25:1, the quantity of catalyst is 1.5 g and the volume of dimethylbenzene is 20 mL,the yield of methylacrylic dodecyl alcohol ester was 96.6% .
