使用红外光谱分析仪对614羟基化产物进行结构分析，对比判断614羟基化是否成功。取614加入硫代甘油和光催化剂在紫外灯照射下反应24h，分离纯化得到614羟基化产品，取一定量的614和其羟基化产物用乙醇稀释，滴加在溴化钾压成的基片上，烘箱60℃1h，进行红外测试。

The structure of 614 hydroxylation product was analyzed by infrared spectrum analyzer, and the success of hydroxylation of 614 was judged by comparison. 614 was added to thioglycerin and photocatalyst under UV irradiation for 24h, and 614 hydroxylated product was separated and purified. A certain amount of 614 and its hydroxylated product were diluted with ethanol and then added to the substrate pressed by potassium bromide in a oven at 60℃ for 1h for infrared test.
