Resumen:
Glycerol is the main byproduct of biodiesel production. Nowadays, glycerol surplus is becoming a matter of environmental and economic concern. Therefore, new ideas to convert glycerol in more valuable compounds are needed. Monoglyceride (MG) synthesis by glycerol (Gly) transesterification with fatty acid methyl esters (FAME), Figure 1, is an attractive option to transform this biomass-derived compound into fine chemicals. MG´s are used as surfactants in food, cosmetics and pharmaceuticals. Nowadays, this process is promoted by corrosive, non- recyclable liquid mineral bases. Then, the use of a solid base catalyst would present several technological and environmental advantages. In this paper, the solid base-catalyzed transesterification of Gly with oleic acid methyl ester was studied. Optimum operational conditions to avoid diffusional limitations were determined. The effect of the reaction temperature and Gly/FAME ratio on the MG yield was investigated as well as those of catalyst surface properties
