Rapid separation of reduction products of 2,4,6-trinitrotoluene using TLC

Silica gel TLC methods were developed for the separation of 2,4,6-trinitrotoluene (TNT) in mixtures with possible reduction products. The methods employed repeated elutions with simple binary or ternary solvent systems in either one or two dimensional modes. The resolved analytes include TNT, selected amino derivatives (2-amino-4,6-di-nitrotoluene, 4-amino-2,6-dinitrotoluene, 2,4-diamino-6-nitrotoluene) and known hydroxylamino derivatives (2-hydroxyl-amino-4,6-dinitrotoluene, 4-hydroxylamino-2,6-dinitrotoluene and 2,4-dihydroxylamino-6-nitrotoluene).
