摘要
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.
