A process for the preparation of a dialkyl arylate includes reacting an aromatic acid, anhydride, or di(C1-3alkyl)ester thereof with a C5-13 alcohol in the presence of an acid catalyst to provide a reaction mixture comprising the dialkyl arylate. The acid catalyst can include sulfuric acid, a sulfonic acid, or a combination including at least one of the foregoing, and can be present in an amount of 0.1 to 0.5 mole percent, based on the moles of the aromatic acid, anhydride, or di(C1-3alkyl)ester thereof. The aromatic acid, anhydride, or di(C1-3alky l)ester thereof and the C5-13 alcohol are present in a molar ratio of at least 1:2.2.
一种制备双烷基芳酸酯的方法,包括在酸催化剂的存在下将芳香族酸、酐或二(C1-3烷基)酯与C5-13醇反应,以提供包含双烷基芳酸酯的反应混合物。酸催化剂可以包括
硫酸、
磺酸或至少包括其中一种的组合物,并且可以按照芳香族酸、酐或二(C1-3烷基)酯的摩尔数的0.1至0.5摩尔百分比存在。芳香族酸、酐或二(C1-3烷基)酯和C5-13醇的摩尔比至少为1:2.2。
