The solubilities of an 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, N-methyl pyrrolidone,… Click to show full abstract
The solubilities of an 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, N-methyl pyrrolidone, and 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 solubility 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 the fitting processes gave satisfying values of the correlation coefficient (R2) and the root-mean-square-deviation. The measurements and the correlation of CBNT solubility provide fundamental data for its practical application.
