摘要：

The preparation of monoglycerides from fatty methyl esters and glycerol can be carried out in the presence of acid or basic catalysts. Moreover, the use of porous and basic solid catalysts could induce a shape selectivity modifying the monoglyceride selectivity. Lauric (C 12), myristic (C 14) and stearic (C 18) acid methyl esters were used in the reaction with several MCM-41 magnesium-containing catalysts. Over an Mg-MCM-41 catalyst (interreticular distance d(100) of 3.4 nm), glycerol monolaurate was obtained with selectivity and yield of about 80%. (C) 2004 Academie des sciences.
