, (2008/06/13)
An improved process for the preparation of glycidyl ethers of formula I STR1 wherein Q is an aliphatic, cycloaliphatic or araliphatic radical of a valency m, R is --H or --CH3, and m is an integer from 1 to 10, by reacting an alcohol of formula Q--(OH)m with m mol of an epihalohydrin of formula II STR2 in the presence of a catalyst to the corresponding halohydrin ether, and dehydrohalogenating said halohydrin ether with an alkali metal hydroxide to give a compound of formula I, wherein Q, m and R are as defined above and Hal is halogen, which process comprises using as catalyst a) tin difluoride or b) a divalent tin halide in conjunction with a co-catalyst.
