Abstract：Using pentaerythritol, allyl chloride and sodium hydroxide as main raw materials, under the action of the phase transfer catalyst, pentaerythritol allyl ether is obtained by Willamson reaction. The effects of the dosage of phase transfer catalysts, molar ratio of reactants, reaction temperature and reaction time on the synthesis reaction were studied respectively. The synthetic process of pentaerythritol allyl ether was optimized, and the total yield under the optimized conditions was 83.1% with a triether selectivity of 82.9%. This synthetic route has simple operation, mild experimental conditions, and low cost of raw material equipment, and is suitable for industrial production.

Key words：pentaerythritol allyl ether; phase transfer catalyst; selectivity; polyether
