HIGH-PURITY EPOXY COMPOUND AND METHOD FOR PRODUCING SAME

摘要

Provided are: N,N,N',N'-tetraglycidyl-3,3'-diaminodiphenyl ether; and a method for producing same. N,N,N',N'-tetraglycidyl-3,3'-diaminodiphenyl ether is produced by an addition reaction step wherein 3,3'-diaminodiphenyl ether and epihalohydrin are reacted with each other in a solvent that contains a protic solvent, thereby producing N,N,N',N'-tetrakis(3-halo-2-hydroxypropyl)-3,3'- diaminodiphenyl ether and a cyclization reaction step wherein the N,N,N',N'-tetraglycidyl(3-halo-2-hydroxypropyl)-3,3'- diaminodiphenyl ether is treated with an alkali for dehydrohalogenation.
