Abstract
A process for the preparation of allyl ethers of the formula EQU R--O--CH.sub.2 --CH.dbd.CH.sub.2).sub.n in which R and n are as defined in claim 1, by reacting hydroxy compounds of the formula EQU R--OH).sub.n with allyl chloride or allyl bromide by phase transfer catalysis, 0.8 to 5 mols of allyl chloride or allyl bromide, 1 to 6 mols of aqueous or solid sodium hydroxide and, as the phase transfer catalyst, 2 to 20 mol % of a quaternary ammonium salt, a quaternary ammonium base or a crown ether being employed per hydroxyl equivalent of the compound of the formula II, and the reaction being carried out in the temperature range from 20.degree. to 100.degree. C.
