ABSTRACT:
A method of preparing tris(2-hydroxyethyl)isocyanurate (THEIC) is disclosed. The method comprises the step of heating a mixture of ethylene carbonate and isocyanuric acid in the presence of a catalyst at a temperature between about 160.degree. C. and 170.degree. C. The molar ratio of ethylene carbonate to isocyanuric acid is at least about 3 to 1, and the catalyst has at least one amine functional group. THEIC produced by the disclosed method can be used without purification as a cross-linking agent in polyester-based magnet wire enamels.
