Evendijk, J. E. published the artcileSeparation and identification of explosive powder with two-dimensional thin-layer chromatography, Product Details of C12H9N3O4, the publication is Explosivstoffe (1968), 16(7), 152-4, database is CAplus.
Up to 18 components encountered in explosive powder mixtures can be completely separated and easily identified by thin-layer chromatog. by using 0.3-mm. SiO2 gel HF254 layers on glass plates. From 20 to 230 mg. of a powder mixture is extracted with CH2Cl2 and applied to glass plates by using as a pouring solution a 20:23 mixture of PhCl and ClCH2CH2Cl.
Explosivstoffe published new progress about 1821-27-8. 1821-27-8 belongs to catalysis-chemistry, auxiliary class Nitro Compound,Amine,Benzene, name is Bis(4-nitrophenyl)amine, and the molecular formula is C12H9N3O4, Product Details of C12H9N3O4.
