摘　　要：以氯乙酸和异辛醇为原料,用Mo+6掺杂制备SO2-4/TiO2/MoO3的固体超强酸催化剂催化合成氯乙酸异辛酯,研究了酯化反应的优化条件。当n(异辛醇):n(氯乙酸)为1.1∶1;催化剂用量为反应物料质量的2.0%时,反应时间90min,氯乙酸异辛酯的收率达到95.5%。2-Ethylhexyl chloroacetate was synthesized by chloroacetic acid and 2-ethylhexyl alcohol by solid superacid catalyst SO^(2-)_4/TiO_2/MoO_3 in Mo^(+6) doping prepared, and reaction conditions have been discussed. The yield of the ester could reach 95.5% under the amount of moler ratio of 2-Ethylhexyl alcohol to chloroacetic acid 1.1∶1. Time of reaction was 90 min. Amount of catalyst was 2.0%.
