  公开（公告）日：2011-10-13

  The invention relates to a method for producing carboxylic esters by converting a carboxylic acid or a carboxylic acid anhydride or a mixture thereof with an alcohol in a reaction system comprising one or more reactors, wherein reaction water is distilled as alcohol-water-azeotrope with the vapors, the vapors are at least partially condensed, the condensate is separated into an aqueous phase and an organic phase and said organic phase is supplied at least partially back into said reaction system. Components boiling lower than the alcohol are at least partially removed from said returned organic phase such as wherein components boiling lower than alcohol are evaporated and/or distilled off. An enrichment in the reaction system of by-products boiling lower than alcohol is avoided. Alcohol losses can be minimized by discharge currents.

  本发明涉及一种通过将羧酸或羧酸酐或两者混合物与醇在一个或多个反应器中反应以产生羧酸酯的方法，其中反应水与蒸汽一起以醇-水共沸物的形式蒸馏，蒸汽至少部分冷凝，冷凝液分为水相和有机相，并且该有机相至少部分地重新供回到反应系统中。从返回的有机相中至少部分去除沸点低于醇的组分，例如蒸发和/或蒸馏沸点低于醇的组分。避免在反应系统中富集沸点低于醇的副产物。通过排放流可以使醇的损失最小化。
