Claims (6)

1. Способ получения сложных эфиров карбоновых кислот взаимодействием ди- или поликарбоновых кислот или их ангидридов со спиртами, причем реакционную воду удаляют со спиртом азеотропной дистилляцией, отличающийся тем, что количество жидкости, удаленную азеотропной дистилляцией из реакции, полностью или частично снова заменяют спиртом.1. A method of producing esters of carboxylic acids by the interaction of di- or polycarboxylic acids or their anhydrides with alcohols, the reaction water being removed with alcohol by azeotropic distillation, characterized in that the amount of liquid removed by azeotropic distillation from the reaction is completely or partially replaced again with alcohol. 2.
