Determination and Correlation of Solubility of Benzotrifuroxan in 12 Pure Solvents at Temperatures Ranging from 293.15 to 333.15 K

Le résumé fourni par la source

Benzotrifuroxan (BTF), as a green hydrogen-free explosive, has a critical impact on its application performance due to its purity. However, there is a lack of systematic research on its solubility in the literature. This study used laser dynamics to systematically measure the solubility data of BTF in 12 pure solvents (methanol, ethanol, n-propanol, n-butanol, chloroform, carbon tetrachloride, polar solvents: acetonitrile, acetone, ethyl acetate, formic acid, acetic acid, and propionic acid) within the temperature range of 293.15–333.15 K for the first time. To establish a reliable solubility prediction model, the Apelblat equation, Yaws model, Van’t Hoff equation, NRTL model, and Wilson model were used to fit and analyze the experimental data. The results indicate that the Yaws equation has the highest goodness of fit ( R 2 > 0.99) and can accurately correlate the dependence of BTF solubility on temperature and solvent properties. This study not only fills the gap in the basic physical property data of BTF, but also provides a theoretical basis for solvent screening and process optimization in its industrial refining process, further promoting the application of BTF in the field of energetic materials.
