Abstract:

The ultrasound was used to promote the resolution of glycidyl butyrate catalyzed by lipase.  The effects of ultrasound source, ultrasonic processing method, power and temperature were also investigated to obtain the optimum reaction conditions. Under the optimum conditions, the enzyme activity of BSL2 in the resolution of glycidyl butyrate was enhanced by about 4.3fold and the enantioselectivity increased by about 5.0fold.
