Crystallization thermodynamics of 2,4(5)-dinitroimidazole in eleven pure solvents
文献摘要：
2,4(5)-Dinitroimidazole(2,4(5)-DNI)is an important energetic material,and it is also an important pre-cursor for the preparation of drugs and energetic materials.In this study,the solubility of 2,4(5)-DNI in eleven pure solvents(chlorobenzene,benzene,1,2-dichloroethane,toluene,water,isopropyl alcohol,ethyl acetate,acetonitrile,methanol,1,4-dioxane and acetone)were measured by using a dynamic test method from 278.15 K to 323.15 K under 101.1 kPa.Four solubility models were used to fit the experi-mental data,which were ideal model,modified Apelblat equation,polynomial empirical equation,and λh equation.Meanwhile,the relative average deviation and root-mean-square deviation between the exper-imental data and the fitted data were also calculated.Furthermore,the three thermodynamic parameters,i.e.,dissolution enthalpy,dissolution entropy and Gibbs energy were obtained based on solubility data.Finally,the crude product of 2,4(5)-DNI was crystallized with acetone as solvent,and the purity of the crystalline product was greater than 99.5％.
