To produce 1,3,5 - trinitrobenzene by the direct oxidation of the 2,4,6 - trinitrotoluene a nitric acid

摘要

The invention relates to the direct oxidation of the 2,4,6 - trinitrotoluene to the nitric acid for the production of the symmetrical trinitrobenzene. & br / is at a temperature greater than 150°C. and at a pressure greater than 15 bar the 2,4,6 - trinitrotoluene, alone or mixed with of the isomers trinitrés and of the 2,4 - dinitrotoluene, with an excess of concentrated nitric acid. & br / the 1,3,5 - trinitrobenzene can be used as an explosive and the raw material for the production of 1,3,5 - trihydroxybenzene (or phloroglucin) and its derivatives.
