Abstract Allyl pentaerythritol was synthesized with pentaerythritol, sodium hydroxide and allyl chloride as raw materials by Williamson etherification reaction. Response surface methodology (RSM) was used to analyze reaction temperature, concentration of NaOH and amount of catalyst on the yield of allyl pentaerythritol, and a correlation model on the optimized synthesis yield of allyl pentaerythritol was presented. The analysis results showed that the interactions between reaction temperature and amount of catalyst,concentration of NaOH and amount of catalyst affected the response variables significantly. The optimized synthesis conditions of allyl pentaerythritol with the catalyst of tetrabutylammonium bromide were obtained when reaction temperature was 78.0 ℃, concentration of NaOH was 54.9%, amount of catalyst was 11.1%, the optimized yield was 70.2%.
