A solution of 1.78 g (0.01 mol) of dipbenylacetylene in 20 mL of glyme is added to a solution of 8.9 g (0.02 mol) of thallium trinitrate in 10 mL of water containing 5 mL of 70% perchloric acid. The mixture is gently refluxed for 3 h. After the mixture has been cooled, thallium mononitrate is filtered off, and the filtrate is diluted with 100 mL of water. The mixture is extracted with two 25-mL portions of chloroform. The chloroform extract is dried with anhydrous sodium...

Current processes for the manufacture of trinitrotoluene (TNT) produce atmospheric and water pollution that is only partly relieved by mechanical clean-up methods. TNT is currently produced from toluene by successive mono-, di-, and trinitrations with mixed aqueous nitric and sulfuric acids in the first two steps and anhydrous mixed acid in the last. Each stage in the current process is conducted at elevated temperatures, and side reactions in the overall process directly produce thousands of pounds of oxides of nitrogen, sulfuric acid aerosols, and volatile nitro organic products (such as tetranitromethane and nitroaro-matics). These pollutants derive from the thermal decomposition of the aqueous nitric acid solutions, from oxidative side reactions that produce as many as 40 by-product compounds, and from formation of unsymmetrlcal "meta" Isomers. Since symmetrical TNT is inevitably accompanied by meta isomers as well as oxidation products, the crude material is treated with sodium sulfite solutions to remove the undesirable Isomers and nitroaromatics by derivatization. The spent sulfite solution, known as "red water, is then disposed of by combustion to an inorganic ash. Itself a disposal problem. 

The lanthanide-nitrate interaction in anhydrous acetonitrile was investigated by means of conductimetry, vibrational spectroscopy, and luminescence measurements which are very sensitive to changes in the first solvation sphere of the metal ion (Bunzli and Choppin 1989). Conductimetiic data on 0.0001-0.01 M solutions of europium or terbium trinitrate in anhydrous acetonitrile indicate that no dissociation occurs. The vibrational spectra show the presence of coordinated acetonitrile and the nitrato group frequencies are consistent with bidentate anions of approximate C2v local symmetry (Bunzli et al. 1978). When the concentration of nitrate is increased, the formation of [R(N03) ] "b species (n>3) is clearly evidenced in the FT-IR spectra (Mabillard 1983). The coordination numbers determined for Nd, Eu, Tb and Er in solutions containing an excess of nitrate are constant (9.9 0.3) and correspond to the formation of pentanitrato [R(N03)5] species, in which the nitrate ions are bonded in a bidentate fashion and which do not contain any coordinated acetonitrile molecule. The strong nitrate/europium interaction is evidenced when water is added to acetonitrile solutions of europium trinitrate. The first two acetonitrile molecules are quantitatively replaced by water molecules, but the replacement of the remaining solvent molecules is difficult to achieve and requires...
