用CMR谱测定长链烷基胺类的—N—CH_2—,—N—CH_3以及季铵盐氮原子上甲基(—N+—CH_3)和亚甲基(—N+—CH_2R)的化学位移并进行定性或定量。本文对十五个化合物进行了~13C谱测定,获得了初步规律性。
The chemical shifts of long chain alkylamines -N-CH 2 -, -N-CH 3 and methyl (-N + -CH 3) and methylene (-N + -CH 2 R) on quaternary ammonium nitrogen atoms were determined by CMR Qualitative or quantitative. In this paper, ~ 13 C spectra of fifteen compounds were measured and the preliminary regularity was obtained.
