Acta Chromatographica No. 7, 159-171 (1997). TLC of 9 nitrophenones, including isomers and closely related compounds, and reduced derivatives and corresponding alcohols on silica, alumina, and Florisil, with mixtures of ethyl acetate or 2-propanol and heptane. Detection under UV 254 nm. Study of the effect of reduction on the separation of the investigated compounds and on the selectivity of the separation of both groups of substances on various polar sorbents.

J. High Resol. Chromatogr. 7, 520-524 (1984). TLC of 1-nitropyrene after pre-chromatographic reduction as 1-aminopyrene on silica, impregnated with a mixture of 2,6-di-tert.butyl-4-methylphenol and Faublin H-Vac. with hexane - anisole 7:3. Quantitative scanning by fluorescence. Fluorometry.

J. Planar Chromatogr. 12, 394-397 (1999). HPTLC of trinitrotoluene (TNT), cyclonite (RDX), Tetryl, PETN, Ng-Nc on silica gel in a tank previously saturated with mobile phase for ca. 45 min; first development with trichloroethylene - acetone 4:1 and then with petroleum ether - acetone 17:3. Detection by spraying with ethanolic KOH resulting in a reddish-orange spot for TNT. The plate was then heated at 120°C for 10 min, cooled, and sprayed with sulfanilic acid and a-naphthylamine reagent. Observation of other explosives.

J. Chromatogr. 295, 299-303 (1984). TLC of nitrohydroxyacylphenones on silanized silica C18 with chloroform - hexane 1:9 or methanol - water 65:35. Detection by UV at 254 nm.

J. Planar Chromatogr. 15, 349-353 (2002). HPTLC of the dansyl derivatives of N-nitrosodimethylamine, N-nitrosodiethylamine, and N-nitrosodibutylamine on silica gel with hexane - ether - dichloromethane 10:3:2. Quantitation at 317 nm and 521 nm with a fiber-optic based fluorescence instrument for in-situ scanning. The presence of polyoxyethylene-10-lauryl ether (dipping of the plates in a mixture of the surfactant and a volatile organic solvent) enhances both the fluorescence intensity and the signal-to-noise ratio. Detection limits, which ranged between 0.47 and 0.89 ng, were five times lower than those obtained in the absence of the surfactant.

J. Chromatogr. 357, 440-444 (1986). Two-dimensional TLC of aliphatic and heterocyclic nitro derivatives on silica with petrol ether - dichloromethane, petrol ether - acetone, petrol ether - ethyl acetate, chloroform - acetone or petrol ether - benzene - acetone in various combinations. Detection by spraying with 1 % diphenylamine in ethanol - acetone 1:1.

J. Planar Chromatogr. 15, 349-353 (2002). HPTLC of the dansyl derivatives of N-nitrosodimethylamine, N-nitrosodiethylamine, and N-nitrosodibutylamine on silica gel, protected from light, with hexane - ether - dichloromethane 10:3:2. A fiber-optic-based fluorescence instrument for in-situ scanning was used for quantitative measurements at 317 and 521 nm. Dipping the plates in a mixture of the surfactant polyoxyethylene-10-lauryl ether enhanced both the fluorescence intensity and the signal-to-noise ratio of the dansyl derivatives. The detection limits ranging between 0.47 and 0.89 ng were five times lower than those obtained in the absence of the surfactant.

J. Chromatogr. 368, 472-475 (1986). TLC on silica with toluene - ethyl acetate 1:1. Detection by spraying with 0.1 % sodiummetaperiodate and 0.5 % potassium permanganate in 4 % solution of sodium hydroxide and heating at 100 °C for 1-5 min. The reported procedure is also useful for the isolation of other related organic nitrate esters including erythrityl tetranitrate, pentaerythritol tetranitrate and mannitol hexanitrate. Isosorbide dinitrate, nitroglycerin.
