摘 要: 选择了异丙醇羧酸铝催化2-(2-甲基烯丙氧基)苯酚合成呋喃酚;探讨异丙醇羧酸铝用量对合成呋喃酚反应的影响.实验结果表明,异丙醇羧酸铝可高效催化2-(2-甲基烯丙氧基)苯酚合成呋喃酚.当催化剂为异丙醇二乙酸铝,用量为2-(2-甲基烯丙氧基)苯酚的2.50%(物质的量比),呋喃酚的收率达到80.8%,高于目前工业上以异丙醇铝为催化剂的78.3%,具有应用价值. Efficient synthesis of carbofuran phenol from 2-(2-methylallyloxy)phenol was achieved by using (RCO2)nAl(OPr-i)3-n as the catalysts. The effect of molar ratio of catalyst (RCO2)nAl(OPr-i)3-n-(2-methyllallyloxy)phenol on the yield was investigated. By employing (CH3COE)EAlOPr-i as the complex catalyst, the yield of carbofuran phenol was improved to 80.8%, which was higher than that of 78.3% in commercial installation.
