Abstract

The first application of WS₂, a well-known graphene analogue, as a solid acid catalyst for carboxylic acid esterification is reported. WS₂ exhibits excellent specific activities and high conversion to methyl esters of (65–90%) for C2–C16 carboxylic acid esterification with methanol under mild conditions, with Turnover Frequencies between 80 and 180 h⁻¹, and outstanding water tolerance even under equimolar water spiking. WS2 also exhibits good stability towards methyl propanoate in the continuous esterification of propanoic acid, and is a promising candidate for biofuels production.
