1,2-Dimethyl-3,5-dinitrobenzene → HCID 86751870, compound

Participants

Reaction Steps

The first filtrate from the separation of 1,2,6-trinitro-o-xylene was extracted three times with 80 ml portions of methylene chloride. The extracts were combined and the volatiles were evaporated to yield an oily mixture of 3,5-dinitro-o-xylene with both of the trinitro-o-xylene isomers. This oil was crystallized from 12 parts of isopropyl alcohol to afford 27.4 g (91.7% yield) of pure 1,4,6-trinitro-o-xylene having a melting point of 72° C. as given by Crossly et al.
