  摘要：

  AbstractThe esterifications of glycerol with cinnamic acid, 2‐methoxy cinnamic acid, and 4‐methoxy cinnamic acid were investigated in batch reactions. Conversions of over 50% were achieved for cinnamic acid and 4‐methoxy cinnamic acid within 8 h. After 24 h, conversions of over 80% were obtained for cinnamic acid and 4‐methoxy cinnamic acid. Conversions of 33 and 40% were observed for 2‐methoxy cinnamic acid after 8 and 24 h, respectively. These reactions were modeled by a system of sequential first‐order rate expressions. Kinetic parameters were estimated from experimental data fit to the model equations.

  4-Methoxy cinnamoyl glycerol (4MCG) is a very promising UV filters material in personal care products. In order to effectively improve the yield of 4MCG, a systematic study on ultrasonic pretreatment enzymatic esterification for 4MCG products was carried out. An ultrasonic frequency of 35 kHz, ultrasonic power of 150 W and ultrasound irradiation time of 1.5 h was determined to guarantee satisfactory

  4-甲氧基肉桂酰甘油（4MCG）是个人护理产品中非常有前途的紫外线过滤材料。为了有效提高4MCG的收率，对4MCG产品进行超声波预处理酶促酯化进行了系统的研究。确定超声频率为35 kHz，超声功率为150 W，超声辐照时间为1.5 h，以确保令人满意的酯化度和脂肪酶活性。在65°C的有机溶剂体系中以4MCA与甘油的摩尔比为1：5，酶的量为15 mg / mL达到最佳产量，在48 h和24 h后单酯收率分别达到66％和55％以上超声波预处理的反应分别。研究了实验动力学数据。反应是通过顺序的一阶速率表达式系统建模的，动力学参数是根据与模型方程拟合的实验数据估算的。结果表明，在超声预处理过程（24 h）中，单酯收率是机械搅拌过程中单酯收率的1.5倍以上，而对脂酶活性没有实质性损害。在转化率和单酯收率方面，超声预处理的酶法明显优于酶法和化学法的机械搅拌。这些结果对应用超声预处理方法制备4MCG具有
