四氧化二氮中相当水含量的分析检测方法

Analysis methods to determine equivalent water content in nitrogen tetroxide

四氧化二氮和加入一定比例一氧化氮的四氧化二氮是非常重要的火箭推进剂,相当水含量是其最重要的一项技术指标。本文对四氧化二氮中相当水含量的分析检测方法包括气相色谱法、近红外光谱法、微波法、核磁共振法等分别进行介绍,并重点介绍核磁共振法的原理及其应用。

Nitrogen tetroxide and nitrogen tetroxide that contained certain proportional nitrogen oxide are the important rocket propellants, and the equivalent water content is one of the most important technique index. The analysis methods to determine the＇equivalent water content in nitrogen tetroxide are introduced in this paper, including gas chromatography method, near-infrared spectra method, microwave method and NMR method. The theory and the application of NMR method is emphasized in the paper.
