Cinnamyl chloride is an organic compound, the molecular formula is C9H7ClO.
Derived from the reaction of sodium cinnamate with oxalyl chloride. Blend oxalyl chloride and benzene into a solution, add the dried sodium cinnamate several times with stirring from time to time, add each time until the reaction releases carbon dioxide and then add the next time. Then reflux for 2h. After a little cold, the produced sodium chloride and a small amount of unreacted sodium cinnamate were filtered off. The filtrate was first distilled off benzene under normal pressure, and then distilled under reduced pressure to collect a 131 ° C (1.47kPa) fraction, and the product was obtained with a yield of 75-90%. When purification is required, it can be recrystallized from carbon tetrachloride. Cinnamic acid is reacted with dichlorosulfoxide to prepare cinnamoyl chloride.
