Partial esters of polyols such as glycerol, polyglycerols and sorbitol are nonionic
surfactants used as emulsifiers in the food, detergents and cosmetics industries.
The commercial large-scale production of these chemicals relies on traditional
homogeneous catalysis processes making use of strong mineral acids or alkalis. This
technology possesses severe drawbacks, related to the generation of large amounts of
by-products, high energy demand, and heterogeneity of the ester mixtures obtained. The
development of new processes based on more selective solid catalyst has therefore a
great economical interest. This contribution reviews the scientific and technical
literature in this field. It is proposed that solid catalysts based on MCM-41 and other
mesostructures could give rise to the development of new, more efficient processes for
the large-scale synthesis of fatty acid esters of polyols.
