“…The authors reported the high activity of this catalyst compared to other solids, attributed to the high dispersion of the heteropolyacid on the support. Furthermore, they concluded that PMVP confers a hydrophobic environment, which prevents the deactivation of PTA by the presence of water [149].…”

Biomass allows us to obtain energy and high-value-added compounds through the use of different physical and chemical processes. The glycerol obtained as a by-product in the synthesis of biodiesel is considered a biomass compound that has the potential to be used as a raw material to obtain different chemical products for industry. The development and growth of the biodiesel industry allows for the projection of glycerol biorefineries around these plants that efficiently and sustainably integrate the biodiesel production process together with the glycerol transformation processes. This work presents a review of the ketalization and esterification of glycerol to obtain solketal and acetylglycerols, which are considered products of high added value for the chemical and fuel industry. First, the general aspects and mechanisms of both reactions are presented, as well as the related chemical equilibrium concepts. Subsequently, the catalysts employed are described, classifying them according to their catalytic nature (zeolites, carbons, exchange resins, etc.). The reaction conditions used are also described, and the best results for each catalytic system are presented. In addition, stability studies and the main deactivation mechanisms are discussed. Finally, the work presents the kinetic models that have been formulated to date for some of these systems. It is expected that this review work will serve as a tool for the advancement of studies on the ketalization and esterification reactions that allow for the projection of biorefineries based on glycerol as a raw material.

The extensive use of biodiesel leads to the excess of glycerol as a by‐product. But as a carbon resource, it has been increasingly used in organic synthesis of high value‐added derivatives in recent years. Among them, solketal is one of the most important derivatives of glycerol, which is generated by the reaction of glycerol and acetone. Based on a large number of relevant literatures, this paper systematically summarized the relevant researches in recent ten years. We systematically summary the latest research progress on the synthesis of solketal by glycerol and acetone. We have focused on a systematic study of four different reaction mechanisms for the ketonation reaction of glycerol and acetone. And the types of catalysts were classified into two categories, homogeneous catalysts and non‐homogeneous catalysts, and the non‐homogeneous catalysts were further classified in more details for the study. This review provides a more comprehensive reference for the ketal reaction of glycerol and acetone, and develops some new ideas for the transformation.
