报道了WS 2作为固体酸催化剂在羧酸酯化反应中的首次应用。WS 2在温和条件下对C2-C16羧酸与甲醇的酯化反应表现出优异的比活性和高的甲酯转化率（65-90%），转化率在80 - 180 h（-1）之间，并且即使在等摩尔水掺加下也具有出色的耐水性。WS 2在丙酸连续酯化反应中对丙酸甲酯也表现出良好的稳定性，是生物燃料生产的有希望的候选者。(C)2016爱思唯尔B. V.保留所有权利。
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. (C) 2016 Elsevier B.V.
