| 摘 要： | 采用改进的Skraup法,以丙烯醛代替甘油,以邻氨基苯酚、邻硝基苯酚、丙烯醛为原料在盐酸、醋酸存在的条件下合成了8-羟基喹啉.通过正交实验探讨了丙烯醛滴加时间、醋酸用量、丙烯醛用量、邻硝基苯酚用量、反应时间对产率的影响.确定最佳反应条件为:邻氨基苯酚用量为21.8 g(0.20 mol)、邻硝基苯酚用量为14.6 g(0.11 mol)、丙烯醛用量为20.2 g(0.36 mol)、醋酸用量为22.0 g(0.37 mol)、盐酸200 mL、丙烯醛滴加时间为3 h、加热反应时间为1.0 h.此时,8-羟基喹啉的产率达72%.

| Abstract: | By improved Skraup method with acrolein replacing glycerine,8-hydroxyquinoline is synthesized from o-aminophenol,o-nitrophenol,acrolein in the presence of acetic acid and hydrochloric acid.By orthogonal experiment,the effects of different reaction conditions on the yield have been discussed.The optimum reaction conditions are determined as follows: o-aminophenol amount is 21.8 g(0.20 mol),o-nitrophenol amount is 14.6 g(0.11 mol),acrolein amount is 20.2 g(0.36 mol),acetic acid amount is 22.0 g(0.37 mol),hydr... |
