碱金属硝酸盐在1,2-丙二醇—水混合溶剂中15℃和45℃的溶解行为研究
Dissolving behaviors of alkali metal nitrates in the mixed solvents of CH3CHOHCH2OH-H2O at 15 ℃ and 45 ℃
摘要
Abstract
The equilibrium solubilities of alkali metal nitrates in the mixed solvents of CH3CHOHCH2OH/H2O (0～1) at 15 ℃ and 45 ℃,respectively,were studied by the of density-refractive index method on a self-made microdevice.The density and refractive index of the saturated solutions were also determined using DMA4500 densimeter and RXA170 refractive index detector at 15 ℃ and 45 ℃,respectively.The solubility and density for the saturated solutions were found to decrease with an increase concentration of 1,2-propylene glycol,while the refractive index trended to increase.The solubility data,density and refractive index of the saturated solutions have been equated for their relationship using four parameters empirical equation.The salting-out effect indicated that the alkaline metal salts were salted out by 1,2-propylene glycol,where the higher the temperature,the slightly bigger the salting-out rate.关键词
