Sun, Lihua published the artcileSolubility, density and refractive index of formamide/N-methylformamide/N, N-dimethylformamide + rubidium bromide/cesium bromide + water ternary systems, Recommanded Product: N-Methylformamide, the main research area is formamide DMF rubidium bromide water ternary system refractive index.
The Solubility, d. and refractive index of the formamide(FA)/N-methylformamide(NMF)/N,N-dimethylformamide(DMF) + rubidim bromide/cesium bromide+ water ternary systems were determined at (283.15, 298.15 and 313.15) K. The solubility of the RbBr and CsBr decrease significantly when adding amides into the aqueous solution The variation trend of d. is consistent with solubility, and the change of the refractive index is different. The isothermal exptl. solubility was correlated by the NRTL model and the UNIQUAC model. The isothermal solubility, d. and refractive index of the ternary systems were fitted by the four parameter equation. Moreover, the mean activity coefficients of the FA/NMF/DMF + RbBr/CsBr + H2O systems at exptl. temperatures were obtained through the UNIQUAC model. Besides, to investigate the temperature effect on the solid-liquid equilibrium, the multiple temperatures solubility was fitted by the modified Apelbl at equation and the λh equation.
