Currently, esterification production of isopropyl myristate (IPM) or isopropyl palmitate (IPP) uses a homogeneous or heterogeneous acid substance as a catalyst and is conducted at high temperatures and pressures. Utilization of this type of catalyst requires an additional postproduction process (neutralization and purification), which burdens the production cost. Microwave enzymatic esterification is a simple and fast method. The results showed that reaction time, ratio molar of fatty acids to isopropyl alcohol, catalyst weight, and microwave power have a significant effect on the IPM or IPP conversion. Further, the energy consumption of this process is less than other enzymatic esterification and is certainly more energy efficient, which could save 99 and 29% of processing time.
目前，肉豆蔻酸异丙酯（IPM）或棕榈酸异丙酯（IPP）的酯化生产使用均相或多相酸性物质作为催化剂，并在高温高压下进行。使用这类催化剂需要额外的后处理过程（中和与纯化），这增加了生产成本。微波酶促酯化是一种简单快速的方法。结果表明，反应时间、脂肪酸与异丙醇的摩尔比、催化剂用量和微波功率对IPM或IPP的转化率有显著影响。此外，该过程的能耗低于其他酶促酯化过程，且能源效率更高，可节省99%和29%的处理时间。
