A process for the preparation of allyl ethers of the formula R-O-CH2-CH=CH2)n in which R and n are as defined in claim 1, by reacting hydroxy compounds of the formula R-OH)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 DEG to 100 DEG C. |
