Trinitrotoluene solubility

Content of 2,4-dinitrotoluene in mixtures with a- trinitrotoluene Solubility of the mixtures (in %) in sulphuric acid of different concentration ... 

Several nitro compounds are soluble in chlorine trifluoride, but the solutions are extremely shock-sensitive. These include trinitrotoluene, hexanitrobiphenyl, hexanitrodiphenyl-amine, -sulfide or -ether. Highly chlorinated compounds behave similarly. 

During the solution of the trinitrobenzoic acid, the temperature should not be below 35°, owing to the slight solubility of trinitrobenzoic acid in cold water. The heat of neutralization raises the temperature to 45-55°, but the latter temperature should not be exceeded, since any trinitrobenzene formed at this point would later be removed with the unreacted trinitrotoluene. 

Cyanuric triazide is insoluble in water, sparingly soluble in cold alcohol and readily soluble in hot alcohol, acetone, benzene, chloroform, ether, and molten trinitrotoluene, It is slightly hygroscopic and slightly volatile. It irritates the skin causing dermatitis. Its heat of formation — AHf is 219kcal/mole (H. Muraour [162]). 

Ref 6) and Clift Fedoroff (Ref 7) described prepn of MeTetryl from beta- and gamma-Trinitrotoluene isomers always present as impurities on the surface of crysts of etude aipha-TNT. The jS and y isomers can be removed by washing the crysts of crude a TNT with 8% aqueous Na sulfite soln (called Sellite). This converts the isomers into water-soluble dinitrotoluene sulfonates. Then, on their treatment with me thy famine the following reaction takes place ... 

Trinitrotoluene (TNT)-based aromatic diamines are used for the preparation of substituted polyimides. Interest in substituted polyimides is very understandable due to the known poor tractability of unsubstimted aromatic polyimides [1—4], As is known, the introduction of methoxy substituents to macromolecules of polyimides enhances their solubility in organic solvents [5]. One of the simplest TNT derivatives, 3,5-diaminoanisole, is used for the preparation of methoxy-substituted polyimides [6]. 

The variety of ways in which chloral and trinitrotoluene (TNT) derivatives can be used to prepare novel polyimides and polymeric materials is very promising. The use of chloral and TNT derivatives allows for the synthesis of a large number of monomers which, in turn, can impart a variety of useful properties to their respective polymers. The possibility of preparing, from available raw materials, high-molecular-weight compounds with increased heat and thermal resistance in combination with improved solubility and, consequently, easiness of processing is especially attractive and may provide impetus for further work in this field.

Solubility, a- Trinitrotoluene is rather insoluble in water. It dissolves in concentrated sulphuric or nitric acids and is precipitated from the solutions on adding water. 

The solubility data for a- trinitrotoluene in sulphuric acid of various concentrations are tabulated in Table 62 (Belenkii [39]). 

Solubility data for a- trinitrotoluene in various mixtures at 20°, 50° said 70°C are shown in Table 63. 

The solubility of a- trinitrotoluene in nitric acid is high even when the acid is relatively dilute (Table 64). This property is sometimes used in industry to crystallize TNT.
