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1004A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 valeric acid/acetic acid, 1004A 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. Infrared comparison with raw materials to determine whether the epoxidation reaction is successful.
