Separation of Nitration By-Products in Commercial-Grade Trinitro-Toluene by High Performance Liquid Chromatography.

摘要

Mixtures of several isomeric mononitro-, dinitro- and trinitro-toluenes were made up in toluene and analysed by HPLC techniques using reverse-phase, silica and amine columns and a variety of eluting solvents. A separation achieved on the silica column using dichloromethane/n-heptane as eluent under optimum conditions indicated that it could be used as a basis for further work in the analysis of production grade trinitrotoluence (TNT).
