摘　　要：以烯丙基氯和CO_(2)为原料、Cu-In复合材料为工作电极、Mg为牺牲阳极,在一室型电解池中常温常压恒电流下电解合成3-丁烯酸。其中,Cu-In复合材料采用电镀方法制备,并利用XRD、SEM和EDX表征。为提高目标产物3-丁烯酸的产率,本文分析了阴极材料电镀时间、溶剂、支持电解质、电流密度、通电量和温度等因素对烯丙基氯电羧化反应的影响。在25℃反应温度、90 min Cu-In复合材料电镀时间、MeCN溶剂、四乙基碘化铵(TEAI)支持盐、3.0 F/mol电解电量、8 mA·cm^(2)电流密度的优化条件下,3-丁烯酸的产率可达56%。此外,在优化条件下还考察了烯丙基溴、肉桂基氯、肉桂基溴、3-氯-2-甲基丙烯等烯丙基卤代物的电羧化反应,结果表明均可得到相应的羧酸,意味着Cu-In双金属电极对催化烯丙基卤代物电羧化反应具一定的普适性。3-butenoic acid was synthesized by constant current electrolysis at room temperature and pressure in a one chamber Electrolytic cell with Allyl chloride and CO_(2) as raw materials,Cu-In composite as working electrode,Mg as anode.Among them,Cu-In composite materials were prepared by electroplating method and characterized by XRD,SEM and EDX.To improve the yield of the target product 3-butenoic acid,the effects of cathodic material electroplating time,solvent,support-ing electrolyte,current density,electricity and temperature on the electrocarboxylation of Allyl chloride were analyzed.The yield of 3-butenoic acid can reach 56%under the optimized conditions of 25℃reaction temperature,90 min Cu-In composite electroplating time,MeCN solvent,Tetraethylammonium iodide(TEAI),3.0 F/mol electrolytic electricity,and 8 mA·cm^(2) cur-rent density.In addition,the electrocarboxylation of Allyl bromide,cinnamyl chloride,cinnamyl bromide,3-chloro-2-methyl-propene and other Allyl group halides was also investigated under the optimized conditions.The results showed that the corre-sponding carboxylic acids could be obtained,which means that the Cu-In bimetallic electrode has a certain universality for the electrocarboxylation of Allyl group halides..
