H-NMR测定氰戊菊酯的立体结构与含量

STUDY ON THE STERIC STRUCTURE AND QUANTITY OF FENVALEMETE WITH 'H-NMR

本文运用核磁共振氢谱法并借助位移试剂Eu(fod)_3测定了氰戊菊酯四种旋光异构体的立体结构及其总含量,并对其R醇与S醇之比进行计算。同时,讨论了对上述结果的影响因素。

The steric structures and the total quatities of four kinds of optical isomers of tenvalerates are determined by 'H Nuclear Magnetic Resonance ('H-NMR) and shift reagent Eu (fod)_3 methods, either their rates of R-alcohol and S — alcohol. Simultaneously, the factors of effect on the results above — mentioned are discussed.
