摘要
以邻甲基环己醇和醋酸酐为原料,采用微通道反应器进行快速反应合成了邻甲基环己基醋酸酯。考察了反应温度、物料摩尔比以及停留时间等工艺条件对产物收率的影响,结果表明,微通道合成邻甲基环己基醋酸酯的最佳工艺条件为:反应温度为70℃、邻甲基环己醇与醋酸酐摩尔比为1∶1.2、停留时间为25 min、催化剂质量为邻甲基环己醇质量的0.5‰。
Abstract
o-Methyl cyclohexyl acetate is rapidly synthesized in a microchannel reactor with o-methyl cyclohexanol and acetic anhydride as raw materials.The effects of reaction temperature,the ratio of raw materials and residence time on product yield are investigated.The optimal process conditions for microchannel synthesis of o-methylcyclohexyl acetate are determined as follows:the reaction temperature is 70℃,the molar ratio of o-methylcyclohexanol to acetic anhydride is 1:1.2,the residence time is 25 min,and the dosage of catalyst is 0.5‰ that of o-methylcyclohexanol.
