使核磁共振波谱仪，测试1HNMR和13CNMR；并与数据库结构进行对比。在甲苯乙酸的环镜下，将1203A与过氧化氢以一定的比例反应4h，再取一部分的样品继续反应（开环反应），将这两部分的反应后的混合物纯化；将1203A、1203A环氧化和1203A环氧开环分别用氘代氯仿溶解后进行核磁测试。

Make a NMR spectrometer to test 1HNMR and 13CNMR; and compare with the database structure. Under the ring microscope of tolueneacetic acid, 1203A and hydrogen peroxide were reacted in a certain proportion for 4h, and then a part of the sample was taken to continue the reaction (ring-opening reaction), and the mixture after the reaction of these two parts was purified; 1203A, 1203A epoxidation and 1203A epoxy ring opening were dissolved with deuterated chloroform and subjected to nuclear magnetic testing.
