Abstract:
PROBLEM TO BE SOLVED: To provide a method for readily producing a polyglycidyl ether in which the total chlorine content is reduced. SOLUTION: The method for producing the polyglycidyl ether represented by general formula (II) (wherein, R 1 and R 2 are each independently hydrogen or 1-4C alkyl; and m and n are each independently a number of 1-10) includes reacting a polyhydric alcohol represented by general formula (I) (wherein, R 1 and R 2 are the same as R 1 and R 2 in general formula (II)) with β-methylepichlorohydrin and an alkali. The reaction is carried out in the presence of a phase-transfer catalyst. COPYRIGHT: (C)2011,JPO&INPIT
