Abstract

This study focused on the synthesis and characterization of tin-exchanged heteropolytungstate (Sn_xTPA) catalysts, which were tested for their efficacy in acetylation of glycerol with acetic acid. The Sn_xTPA catalysts showed significantly enhanced activity compared to the original TPA catalyst, especially for glycerol acetin synthesis. The catalytic performance was strongly correlated with the degree of tin exchange with heteropolytungstate protons. Partially exchanged Sn₁TPA catalyst showed the highest activity owing to variations in acidity. Surface and structural properties of Sn_xTPA catalysts were found to influence their catalytic activities.

Graphical Abstract

Acetylation of glycerol to biofuel additives is achieved using heteropoly tungstate exchange on tin solid catalyst. The role of catalysts and both Bronsted and Lewis acidity on glycerol acetylation was demonstrated.

期刊介绍： Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
