Abstract
The solubility of 3,4-bis(3-nitrofurazan-4-yl)furoxan (DNTF) in propanoic acid + water (PA + water) binary mixed solvents was studied. The solubility of DNTF in the temperature range of 293.15 ~ 333.15 K at atmospheric pressure (0.1 MPa) was measured by a laser dynamic method. In order to expand the applicability of solubility, the Apelblat equation, van’t Hoff equation, GCM Model, and Jouyban-Acree Model were used to correlate the solubility, and satisfactory results were obtained. In addition, apparent thermodynamic parameters such as standard dissolution enthalpy, standard dissolution entropy, and standard Gibbs free energy of DNTF in these solvents were calculated. The solubility of DNTF will provide necessary support for industrial production, crystallization and further theoretical research. These findings provide valuable insights for future research on DNTF crystallization.
期刊介绍：
Journal of Solution Chemistry offers a forum for research on the physical chemistry of liquid solutions in such fields as physical chemistry, chemical physics, molecular biology, statistical mechanics, biochemistry, and biophysics. The emphasis is on papers in which the solvent plays a dominant rather than incidental role. Featured topics include experimental investigations of the dielectric, spectroscopic, thermodynamic, transport, or relaxation properties of both electrolytes and nonelectrolytes in liquid solutions.
