| Abstract: | Benzylidene-acetone is halogenated by hypochloite sodium,Sodium cinnamylate is acidified after the excess hypochlorite has been removed with the reductive agent Sulfite sodium or hydrosulfite sodium,the yield of cinnamylic acid is 78％. Its purity is 95％. The analytical identification proves that the using of reductive agent impoves the yield and purity of cinnamylic acid. |
