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。在甲苯和酸的环镜下，将表面活性剂与过氧化氢以一定的比例反应4h，反应后的混合物纯化；取少量样品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. Under the ring microscope of toluene and acid, the surfactant and hydrogen peroxide are reacted in a certain ratio for 4h, and the reacted mixture is purified; A small amount of sample 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.
