摘要：

The synthesis of cetyl palmitate in hexane has been investigated with immobilized lipase Candida sp.99-125 prepared in our laboratory as the catalyst. The kinetics of the reaction were found to be consistent with the Ping-Pong Bi-Bi mechanism, which is characterized by inhibition by both alcohol and acid. The long-chain alcohol was shown to be the primary competitive inhibitor of the esterification. The inhibition effects of both substrates were studied in three different concentration ranges. Appropriate kinetic models for different substrate concentrations are proposed and the apparent kinetic parameters are calculated.
