type B (CAL-B) as suitable biocatalyst. Special attention has been paid to the role that the solvent plays in the production of ethyl cinnamate. Therefore, volatile organic solvents and deep eutectic mixtures were employed in order to find optimal reaction conditions. Once that hexane was selected as the solvent of choice, other parameters that affect the enzyme activity were investigated in order to
使用乙醇作为亲核试剂和南极假丝酵母深入研究了肉桂酸的酯化反应B型脂肪酶(CAL-B)作为合适的生物催化剂。特别注意了溶剂在肉桂酸乙酯生产中的作用。因此,为了找到最佳反应条件,使用了挥发性有机溶剂和深共熔混合物。一旦选择了己烷作为选择的溶剂,便会研究影响酶活性的其他参数,以便以优异的产率生产肉桂酸乙酯。CAL-B的负载量,亲核试剂的当量,温度和反应时间已被确定为酶效率的关键参数,并且脂肪酶催化的酯化反应的潜力最终被开发出来,以产生一系列在芳族化合物上具有不同模式取代的乙酯戒指。
