摘要
In a two-phase system of D-sorbitol in water and decanoic acid the esterification is catalyzed by lipase from Candida rugosa. The initial esterification rate is 3.0 mmole/g.h and is strongly dependent on the water content of the reaction mixture. In a two-phase membrane reactor the initial esterification rate is 6.8 mmole/g.h. After 570 hours this reaction rate is reduced by 15%, which indicates a fairly good stability of lipase in this membrane system. © 1990 Kluwer Academic Publishers.
