Abstract:
A method for enhancing reaction efficiency of a terephthalate plasticizer involves using a homogenizer to fine PTA to slurry having a particle size of 80-110 μm, and esterifying the PTA slurry with a C6-C10 alcohol in the presence of a titanium-based catalyst. The reactivity is enhanced by more than 37.5%, and the terephthalate plasticizer so synthetized is low-odor and has a purity of more than 99.5% as well as good physical properties such as acid value, color, and index of refraction.

Claim (Index 3):
The method of  claim 1 , wherein water produced during the esterification and the alcohol used are formed in to an azeotrope under vacuum pressure or atmospheric pressure, and the azeotrope is removed from the reaction mixture.
