Monoglycerides are valuable compounds with wide applications as emulsifiers in food, pharmaceutical and cosmetic industries. They can be produced by esterification of glycerols with fatty acids. Traditional homogeneous catalysts are usually used in the reaction for commercial scale productions. The processes utilizing homogeneous catalysts possess some drawbacks due to environmental aspect, such as corrosiveness, hazards of waste catalysts, etc. Because of simplicity in catalysts removal and minimization of the amount of waste formed, the utilization of heterogeneous or solid acid catalysts, as an alternative for this process, is an emerging topic on the aspect of the green–chemical processes. However, diffusion limitation of liquids within porous solids dictates that the use of mesoporous materials with pore diameter ranging from 20oA to 100oA is expected to be successful in liquid-phase reactions. The discovery of a family of ordered mesoporous silicas opens up new possibilities for preparing heterogeneous catalysts for liquid phase reactions. This review highlights on recent developments in the synthesis of mesoporous functionalized acid catalysts, for esterification of glycerols by fatty acids to produce monoglycerides.
