Abstract

Esters of isophthalic acid are made by reacting isophthalic acid with an alkylene oxide in the presence of a quaternary ammonium salt as a catalyst. The reaction may be effected at 70-120 DEG C under autogenous pressure, and the molar ratio of alkylene oxide to isophthalic acid may be from 1:1 to 4:1. An example is given in which isophthalic acid is esterified with 2 mols of propylene oxide in the presence of benzyl trimethyl ammonium chloride. Other suitable catalysts are also specified. Other specified alkylene oxides are ethylene oxide and butylene oxide. The products are useful as intermediates for the manufacture of unsaturated polyester resins.
