摘要
以对甲苯磺酸为催化剂,乙醇为带水剂,柠檬酸与乙醇为原料,通过酯化-蒸汽渗透膜脱水耦合法制备高纯度柠檬酸三乙酯。主要考察了膜面积对反应时间、酯化率、纯度的影响,优化出膜面积并进行了中试实验验证。
The triethyl citrate with high purity is prepared from citric acid and ethanol through esterification-vapor permeation coupling method,using p-toluene sulphonic acid as catalyst and ethanol as dehydrating agent. The effects of membrane area on reaction time,esterification rate and purity are investigated. The membrane area is optimized and the pilot experimental results are also verified.
