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 4):
The method of  claim 1 , wherein the esterification catalyst is removed after esterification using steam and active carbon.
