摘要
用负载型稀土催化剂 ,在无水乙醇介质中 ,用浓硝酸硝化水杨酸 ,使 5 -硝基水杨酸的产率提高到了 80 %以上 ,同时考察了反应温度、反应时间对产率的影响 。
The nitrification of salicylic acid with nitric acid was studied by using supported rare earth as catalysts and ethanol as solvent.The yield of 5\|nitro\|salicylic acid was raised up to 80%.The influences of temperature and reaction time on the yield of the product were investigated,and the optinum condition was acquired.
