Conditions

Temperature: 60 °C

Procedure

A mixture of Novozym® 435 (1 kg), 1-dodecanol (4000 mL), and ethyl lactate (4000 mL) in a 50 L reactor was stirred (˜200 rpm) at 60±5° C. for 28 hours. Upon work-up, 4000 g of lauryl lactate (80% yield) was obtained as a pale yellow liquid. The purity of the product was >97% as assessed by GC.
