Synthesis of hexanitrostilbene (HNS) using a kenics static mixer

Previous work on a Shipp-Kaplan type synthesis of hexanitrostilbene (HNS) using a Kenics static mixer (ref1, from Chemineer Ltd., Cranmer Road, West Meadows, Derby DE21 6XT, UK; www.chemineer.com) has been extended by using a larger mixer (9.5 mm vs 4.75 mm OD), enabling the scale to be increased from 2.5 g to 25 g of trinitrotoluene (TNT) for the same mixing time (2SO4 and NaOH solutions, and (iii) pH control using aqueous RNH3Cl and RNH2 solutions. Other parameters that have been varied are the ratio of NaOCl to TNT (0.5-1.2) and the concentration of both reactants. The yields of crude HNS that have been achieved, whilst not outstanding, are an improvement over the conventional batch process. It has been demonstrated that the yield and selectivity of the HNS synthesis can be considerably increased if, during the after-reaction period, the reaction conditions are pH controlled. The yield and selectivity are also significantly enhanced by using more dilute reaction solutions.

Radical ion reactions of carbanions derived from 4-nitro-, 2,4-dinitro-, and 2,4,6-trinitrotoluenes with polynitroalkanes

4-Nitro-and 2,4-dinitrotoluenes react with tetranitro-and halotrinitromethanes in the presence of bases to give the corresponding nitro-substituted 1,2-diphenylethanes and stilbenes. Reactions of 2,4,6-trinitrotoluene with fluorotrinitromethane, N,N-dinitrotnethylamine, and tert-butyl and isopropyl nitrates result in formation of α,2,4,6-tetranitrotoluene; with chlorotrinitromethane, 2,4,6-trinitrobenzyl chloride is formed.
