✦ Synopsis

Four different approaches for the synthesis of monolaurylglycerol (MLG) by non specific Pseudomonas cepacia lipase in a crude and purified form have been studied: a. The direct esterification of glycerol by lauric acid in bis-(2-ethylhexyl)sulfosuccinate sodium salt (AOT)/isooctane microemulsion systems; b. the transesterification of glycerol by vinyl laurate in the presence or not of any solvent; c. solid-phase glycerolysis of trilaurin; and, d. transesterification of protected glycerol, 1,2-O-isopropylidene glycerol, by vinyl laurate, in the presence or not of any solvent. It was found that in the two latter cases (d and c) the formation of pure MLG was occurred, while in the first two cases (a and b) apart of MLG the formation of DLG was also observed.
