Process for esterification |
摘要 |
A method for the rapid esterification of dicarboxylic acids or the transesterification of lower alkyl carboxylic acid diesters with diols is disclosed. The method includes recycling of evaporated unreacted starting materials and can be carried out at elevated pressures. The resulting esterification or transesterification products can then be polymerized into polyesters, for example by a thin film polymerization method.
