Production method

It is obtained by the reaction of sodium cinnamate and acetyl chloride. Prepare a solution of diacetyl chloride and benzene, add the dried sodium cinnamate several times under the stirring from time to time, and add it again after the reaction emits carbon dioxide. Then reflow for 2h. After slightly cooling, filter out the produced sodium chloride and trace unreacted sodium cinnamate. The filtrate is first evaporated to remove benzene under normal pressure, and then distilled under reduced pressure to collect 131 ℃ (1.47kPa) fraction to obtain the product with a yield of 75-90%. When purification is required, carbon tetrachloride can be used for recrystallization. Cinnamoyl chloride was prepared by the reaction of cinnamic acid and dichloro sulfoxide.
