Title:
METHOD FOR PRODUCING BENZYL DERIVATIVES OF 2-BUTENE-1,4 DIOLS
Document Type and Number:
WIPO Patent Application WO2002022537
Kind Code:
A3
Abstract:
A method for producing benzyl derivatives of 2-butene-1,4-diols by reacting 2-butene-1,4-diols with benzyl chloride compounds in the presence of an alkali or alkaline earth metal hydroxide or carbonate to produce benzyl derivatives of 2-butene-1,4-diols and recovering at least a portion of at least one such benzene derivative.
