摘要
以固体超强酸树脂为酯化催化剂,合成了己二酸二辛酯。考察了醇酸物质的量比、带水剂用量、反应时间及催化剂用量对酯化反应的影响,确定了合成己二酸二辛酯的最佳反应条件。固定己二酸用量为0.1 mol,在醇酸物质的量比为3:1、催化剂用量(以反应物己二酸质量计)1%、带水剂环己烷9 mL,反应时间140 min的条件下,己二酸二辛酯收率可达99.6%以上。
Dioctyl adipate was synthesized by esterification of adipic acid and octanol catalyzed by solid superacid resin. The effects of molar ratio of reactants, amount of water - carrying agent and catalyst, and reaction time on the yield of dioctyl adipate were investigated. And the optimized reaction conditions were determined. The yield of the product could be more than 99.6% under the reaction conditions as follows： molar ratio of octanol to adipic acid 3 ： 1, amount of water - carrying agent and catalyst 9 mL and 1% respectively, and reaction time 140 minutes based on adipic acid 0.1 mol.
