Synthesis and characterization of methyl nitramino -2, 4, 6-trinitrobenzenes using bismuth nitrate pentahydrate as an eco friendly nitrating agent

Abstract

208-210This study presents synthesis of 2,4,6-trinitrophenylmethyl- nitramine (3a) 2,4,6-trinitro-1,3-di(methylnitramino) benzene (3b) and 2,4,6-trinitro-1,3,5-tris(methylnitramino) benzene (3c) by nitration of 2,4,6-trinitro-N-methylaniline (2a), 2,4,6-trinitro- 1,3-di(methylamino) benzene (2b) and 2,4,6-trinitro-1,3,5-tris(methylamino) benzene (2c) using bismuth nitrate pentahydrate in tetrahydrofuran adsorbed on silica gel and fly ash as solid supports under microwave irradiation. An eco-friendly nitration approach used in synthesis of target compounds (3a-3c) is of interest for the production of high energy materials
