Measurement and correlation of the solubility of sodium acetate in eight pure and binary solvents
文献摘要：
The knowledge of solubility of a salt in either the pure solvent or blend solvent is of great importance for studying or operating the crystallization,extraction,and distillation processes.The solubility of sodium acetate(NaAc)in four pure solvents(water,ethanol,acetic acid and 2,2,2-trifluoroethanol)and four bin-ary solvents(water-ethanol,water-acetic acid,acetic acid-ethanol,and acetic acid-ethyl acetate)were measured by using the laser dynamic method at temperatures from 288.15 K to 338.15 K at 0.1 MPa.The results showed that the solubility of NaAc was influenced by either the solution temperature or sol-vent composition.The aqueous sodium acetate solution possessed the maximal solubility under the experimental conditions.The solubility of NaAc in 2,2,2-trifluoroethanol was found to be decreased with the increase of the solution temperature.While,the solubilities of NaAc in other seven solvents increased as the solution temperature was elevated.Besides,five correlation models,including the van't Hoff model,modified Apelblat model,Yaws model,λh model,and modified Apelblat-Jouyban-Acree model were used to correlate the solubility data of those sodium acetate solutions with acceptable deviation,respectively.Finally,van't Hoff analysis method was selected to analyze the change law of thermody-namic properties of a salt during the dissolution process.
