以对氯苯甲酸、甲醇、水合肼、呋喃甲醛、苯甲醛、乙醛为原料，设计合成了呋喃甲醛对氯苯甲酰腙、苯甲醛对氯苯甲酰腙及乙醛对氯苯甲酰腙3种酰腙席夫碱化合物。目标化合物的结构通过核磁共振氢谱、元素分析和红外光谱进行了表征，并试验了目标化合物的杀虫活性。结果表明，呋喃甲醛对氯苯甲酰腙对菜粉蝶幼虫的胃毒活性最强，处理24、48 h后EC50分别为103.61、78.96 mg/L。
以對氯苯甲痠、甲醇、水閤肼、呋喃甲醛、苯甲醛、乙醛為原料，設計閤成瞭呋喃甲醛對氯苯甲酰腙、苯甲醛對氯苯甲酰腙及乙醛對氯苯甲酰腙3種酰腙席伕堿化閤物。目標化閤物的結構通過覈磁共振氫譜、元素分析和紅外光譜進行瞭錶徵，併試驗瞭目標化閤物的殺蟲活性。結果錶明，呋喃甲醛對氯苯甲酰腙對菜粉蝶幼蟲的胃毒活性最彊，處理24、48 h後EC50分彆為103.61、78.96 mg/L。

Taking p-chlorobenzoic acid, methanol, hydrazine hydrate, furfural, benzaldehyde and acetaldehyde as materials, three acylhydrazone schiff base compounds, namely furfural p-chlorobenzoyl hydrazone, benzaldehyde p-chlorobenzoyl hydra-zone and acetaldehyde p-chl-orobenzoyl hydrazone were designed and synthesized. Their structures were confirmed by H-NMR, elemental analysis and the infrared spectrum. The insecticidal activities of target com-pounds were tested against Pieris rapae larvae in lab. The results showed that furfural p-chl-orobenzoyl hydrazone had the strongest stomach toxicity and the EC50 of stomach toxicity 24, 48 h after treatment were 103.61, 78.96 mg/L respectively.
