本文采用苯甲叉基丙二腈作为中间体,与间苯二酚在无水ZnCl2和HCl气体的催化作用下制得亚胺盐,再水解,脱羧,分离得到产物,通过液相色谱、紫外、红外等手段对中间产物和最终产物进行分析鉴定,确定最终产物是7-羟基二氢黄酮。 In this paper, benzylidene malononitrile was used as an intermediate to produce imide salt with resorcinol under the catalysis of anhydrous ZnCl2 and HCl gas, and then hydrolyzed and decarboxylated to obtain the product. The product was isolated by liquid chromatography, UV , Infrared and other means of intermediate products and final product analysis and identification to determine the final product is 7-hydroxy-flavone.
