Solubility of 1,1-Diamino-2,2-dinitroethylene in <i>N</i>,<i>N</i>-Dimethylformamide, Dimethyl Sulfoxide, and <i>N</i>-Methyl-2-pyrrolidone

Abstract

The solubility of 1,1-diamino-2,2-dinitroethylene in dimethyl sulfoxide, N,N-dimethyl formamide, and N-methyl-2-pyrrolidone was measured by a polythermal method in the temperature range of (293.15 to 363.15) K. The solubility data were correlated against temperature with an exponential equation. The enthalpy of dissolution in each solvent was calculated from the temperature dependence.
