Low melting point mixture of di-n-butyl terephthalate and diisobutyl terephthalate

摘要

Mixtures of terephthalate diesters having lowered freezing points and methods of making the terephthalic acid diesters. The method includes contacting a first alcohol, a second different alcohol and dimethyl terephthalate in the presence of a catalyst to thereby form the terephthalate diesters.
