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。在甲苯和乙酸/壬酸的环镜下，将602A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。乙酸和壬酸环氧化反应的产物进行对比，是否存在开环。

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 acetic acid/nonanoic acid, 602A and hydrogen peroxide were reacted in a certain ratio for 4h, and the reacted mixture was 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. Compare the products of acetic acid and nonanoic acid epoxidation reaction with the presence or absence of ring opening.
