摘要
在醋酸、相转移催化剂聚乙二醇存在下 ,2 萘酚与硝酸铈铵反应生成 1 硝基 2 萘酚。对反应条件进行了研究 ,结果表明最佳反应条件为 :2 萘酚与硝酸铈铵的物质的量比为 1∶1 2 ,水浴温度 5 0℃ ,反应时间 1 3h。产率达 86 2 %。
In the presence of acetic acid and polyethylene glycol,2 naphthol reacts with ammonium ceric nitrate to form 1 nitro 2 naphthol.The results showed that when the molar ratio of 2 naphthol to ammonium ceric nitrate was 1∶1 2,with acetic acid 2mL and polyethylene glycol 2mL added,reaction temperature 50℃,reaction time 1 3h,the yield of 1 nitro 2 naphthol was 86 2%.
