MANUFACTURING METHOD OF CYANATE ESTER OF HIGH PURITY

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a cyanate ester for obtaining a cyanate ester of a higher purity in a high yield, while suppressing by-production of a dialkyl cyanamide, imide carbonates or the like. SOLUTION: The manufacturing method of a cyanate ester comprises causing a naphthol compound, a cyanogen halide and a tertiary amine to react under an acidic condition in a two-phase solvent of water and an organic solvent.
