Paragraph 0037-0047, (2021/04/14)
The invention relates to a synthesis method of pentaerythritol triallyl ether, wherein the synthesis method comprises the following steps: reacting pentaerythritol with chloropropene in a hydroxide aqueous solution to generate pentaerythritol triallyl ether, and adding 2-15 wt% of an allyl alcohol accelerator into every 100 parts by weight of pentaerythritol; and after the reaction is finished, separating a reaction product to obtain a product containing pentaerythritol triallyl ether. According to the synthesis method, the allyl alcohol compound is added as a reaction promoter to promote the reaction, the reaction can be carried out under normal pressure without pressurization, so that the problems of safety and economy caused by the need of a pressurization device are solved, and the synthesis method has remarkable economic advantages. In addition, the added allyl alcohol compound has an inhibition effect on byproducts which are originally generated in the reaction process. Moreover, the product is convenient to separate, pollution-free, energy-saving, environment-friendly, simple and convenient in technological operation and high in production efficiency, and can be widely used for preparing pentaerythritol allyl ether.
