Abstract
The new process for preparation of trimethylolpropane diallyl ether is developed using solid sodium hydroxide,trihydroxy methyl propane and allyl chloride as raw materials,and butyl ether as reaction medium and azeotropic dehydrating agent.The key factors affecting the product yield and product quality are controlled and the optimum process conditions are determined.The results show that the high yield of trimethylolpropane diallyl ether can be achieved with less than 8% of ME,more than 90% of DE and less than 1% of TE.The total ether content is greater than 99%.The target product with stable and reliable product quality is obtained with all the indicators better than similar products at home and abroad.
