Abstract

PURPOSE: A batch-wise process for the direct esterification in the presence of a Ti catalyst, characterized in counducting the reaction maintaining the esterification conversion at a level of 85W98% by the control of supply of a mixture consisting of a dicarboxylic acid (e.g. terephthalic acid) and a glycol (e.g. ethylene glycol).
