Title: METHODS FOR SYNTHESIZING HIGH PURITY EPOXY COMPOUNDS AND PRODUCTS OBTAINED THEREFROM
Abstract:
A process for preparing a diglycidyl ether of formula (1) to (9) with epichlorohydrin and a catalyst, for a time and at a temperature to provide a first reaction mixture comprising a dichlorohydrin of formula (1-d) to (9-d); adding a base to the first reaction mixture to provide a second reaction mixture over a period of 15 minutes to 3 hours; and agitating the second reaction mixture for 2 to 5 hours at 40 to 60°C, to provide an as-synthesized diglycidyl ether of formula (1) to (9) having a purity of 96 to 99% or greater as determined by high performance liquid chromatography is provided. An as-synthesized or isolated diglycidyl ether of formula (1) to (9) made by the provided process is provided. A cured composition comprising the cured product of the provided diglycidyl ether, and an article comprising the same are provided.
