Versuchsvorschrift

A mixture of Novozym® 435 (2.43 g), molecular sieves (20.17 g), 1-octadecanol (4.04 g), and ethyl lactate (8.86 g) in a 150 mL beaker was maintained at 60° C. in a convection oven for 28 hours. Upon work-up, 2.0 g of cetyl lactate (40% yield) was obtained as a waxy white solid. The purity of the product was >98% as assessed by HPLC-RI.
