Trinitrobenzoic acid can be prepd by this procedure (see Vol 2, B73-L), but the alcohol and aldehyde are made by other methods, since oxidation cannot usually be stopped at either of these stages, they being more easily oxidized than TNT itself. Trinitrobenzoic acid is easily and quantitatively converted to 1,3,5 trinitro-benzene (TNB — see Vol 2, B48-L), an expl superior in many ways to TNT, but more ex-... 

The thermal decompn of compds related to TNT has also been examined. Trinitrobenzal-dehyde and 4,6-dinitroanthranil, two compds identified as being formed during the decompn of TNT as mentioned above, decompose much more rapidly than TNT (Ref 72). The latter compd is thought to be the autocatalyst in the decompn of TNT (Ref 72). The thermal decompn of trinitro-benzenes containing other alkyl substituents, or NH2, Cl, F, Br, or OH groups (Refs 54 102) has also been studied. In the latter group, the compds containing NH2 and Cl were the most stable... 

A study of second-harmonic generation (SHG) from powders of l,3,5-triamino-2,4,6-trinitro benzene type compounds showed that the parent molecule 6 had an activity of about 3 x urea, whereas N-substituted derivatives were inactive (Ledoux, I. Zyss, J. Lehn, J.-M. Siegel, J. Brienne, M.-J., unpublished data). 

This material is a white solid which exhibits a powder SHG efficiency of 100x quartz. This observation is rather unusual because most molecules designed for the improvement of SHG properties require an extended dipolar structure and consequently have an approximately D2h symmetry, yet 2 has a distorted C3V symmetry. Elsewhere in this symposium, J.-M. Lehn reported that crystals of 1,3,5-triamino-2,5,6-trinitro benzene (TATNB), another molecule of similar symmetry to 2, exhibit a large SHG efficiency. However TATNB can, in principle, distort to a...

The second variable is the nature of the attacking nucleophile and we shall consider first the reactivities of a series of nucleophiles towards a single substrate. Perhaps the most studied compound is 1,3,5-trinitro-benzene and the equilibrium constants for formation of 1 1 adducts with a variety of nucleophiles are given in Table 7. However the stability of a given adduct will vary considerably with change of solvent so that values obtained in different solvents are not comparable. 

Ostromyslensky [90] observed that rubber could be vulcanized in the absence of sulphur or its compounds if small quantities of aromatic nitro compounds, e.g. nitrobenzene, dinitro- or sym- trinitro-benzene, tetranitronaphthalene plus certain oxidizing compounds, such as benzoyl peroxide, were added to it. The resultant vulcanized rubber had mechanical properties not inferior to those of a product vulcanized by sulphur alone, and when free from accelerators it exhibited a greater resistance to ageing. Some metal oxides, such as PbO, CaO, BaO, promoted vulcanization by nitro compounds. Urea played the role of an accelerator of vulcanization. These observations have been confirmed in more recent studies by other workers.

To about 0.54 g. of 9,10-dihydroanthracene in 25 ml. of ethanol, 8 g. of Raney nickel catalyst was added. After refluxing for 2J hours in an atmosphere of nitrogen, the mixture was filtered and the filtrate was concentrated. On cooling, about 0.33 g. of 1,2,3,4-tetrahydroanthracene was obtained. The mother liquor, when treated with 0.3 g. of s-trinitro-benzene, yielded about 0.25 g. of the 1,2,3,4-tetrahydroanthracene-tri-nitrobenzene complex. The total yield was 81% of the theoretical. When about 0.34 g. of anthracene in 50 ml. of ethanol was treated with 10 g. of Raney nickel, a 71 % yield of the same product was obtained.
