摘要
苄叉丙酮经次氯酸钠卤化反应为肉桂酸钠,酸化前用还原剂Na_2SO_3或NaHSO_3除去过量的次氯酸钠,产率达78%,纯度达95%,并用分析鉴定结果表明使用还原剂提高产率和纯度的理论依据。
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.
