通过红外表征测试其官能团，通过分析官能团的增加和减少来证明反应发生。取少量718A用乙醇稀释后滴到以溴化钾压成的基片上，放置烘箱60℃，1h，而后进行红外光谱测试。与原料的红外对比，判断环氧化反应是否成功。

Its functional groups are tested by infrared characterization, and the reaction occurs by analyzing the increase and decrease of functional groups. A small amount of 718A was diluted with ethanol and dropped onto a substrate pressed with potassium bromide, placed in an oven at 60 °C for 1h, and then subjected to infrared spectroscopy testing. Infrared comparison with raw materials to determine whether the epoxidation reaction is successful.
