摘要：

Alkaline- and lipase-catalyzed hydrolysis of 4-nitrophenyldecanoate have been performed in a Winsor I type microemulsion. The reaction occurred in the lower-phase oil-in-water microemulsion. After the reaction was complete a Winsor I-->III transition was induced by a rise in temperature. The products formed, 4-nitrophenol and decanoic acid, partitioned into the upper oil phase and could easily be obtained by separation of this phase and evaporation of the solvent. The surfactant and the enzyme (in the case of the lipase-catalyzed reaction) resided in the middle-phase microemulsion and could be reused. (C) 1997 Elsevier Science B.V.
