Process for the glycidylation of alcohols

Process for the glycidylation of alcohols

A process for the production of glycidyl ether of an aliphatic, cycloaliphatic or araliphatic primary or secondary alcohol, comprising: A) reacting epichlorohydrin with a molar excess of the alcohol in the presence of a Lewis acid catalyst; optionally B) dehydrochlorinating the product so obtained;...

Zusammenfassung:A process for the production of glycidyl ether of an aliphatic, cycloaliphatic or araliphatic primary or secondary alcohol, comprising: A) reacting epichlorohydrin with a molar excess of the alcohol in the presence of a Lewis acid catalyst; optionally B) dehydrochlorinating the product so obtained; and C) reacting the product from step A) or B) with a molar excess of epichlorohydrin in the presence of alkali and a phase transfer catalyst, and then isolating the glycidyl ether product so obtained.
