ABSTRACT

The solubilities of the energetic material 5,5 -dinitramino-3,3 -bi[1,2,4-triazolate] carbohydrazide salt (CBNT) were measured in eleven pure solvents (deionized water, methanol, ethanol, ethylene glycol, isopropanol, ethyl acetate, 1,2-dichloroethane, acetone, N, N-dimethylformamide (DMF), N-methyl pyrrolidone (NMP), dimethyl sulfoxide (DMSO)) and a binary solvent mixture of (DMSO + water) under atmospheric pressure using a gravimetric method. The solubility data in pure solvents were fitted using the modified Apelblat equation. The results provide a satisfactory correlation. The experimental data of CBNT in binary solvents were correlated by the modified Apelblat equation, the combined nearly ideal binary solvent Redlich-Kister (CNIBS/R-K) model and the Jouyban-Acree model. All equations gave good representations of the experimental data. All the work provides a banausic guidance for further crystallization researches of CBNT.
