Qiu, Dan published the artcileSolubility, density and refractive index of formamide/N-methylformamide/N, N-dimethylformamide + Rb2SO4 + H2O ternary systems at 283.2, 298.2 and 313.2 K, Recommanded Product: N-Methylformamide, the main research area is methylformamide sulfuric acid rubidium water ternary system.
In this work, the solid-liquid equilibrium (SLE) of the ternary systems formamide (FA)/N-methylformamide (NMF)/N, N-dimethylformamide (DMF) + Rb2SO4 + H2O was measured at temperatures of 283.2, 298.2, and 313.2 K. The isothermal solubility of Rb2SO4 in mixed solvents, the d. and refractive index of the saturated solutions were determined At a given temperature, with the increase of the amide content in the mixed solvent, the saturated solubility of Rb2SO4 decreased significantly. The d. trend was consistent with the solubility However, the refractive index increased with increasing the content of amide. The solubility increased with increasing the temperature, whereas, the d. curves and refractive index curves at the three temperatures showed a point of intersection. In addition, the influence of the polarity and structure of amide on the solubility of the ternary system was also discussed. Finally, the exptl. data were fitted with empirical equations.
