Solubility of Sodium Acetate in a Water + Acetonitrile Binary Solvent System and the Mixture Density
This study presents the solubility and density of the binary system sodium acetate (NaOAc)–water and the ternary system NaOAc–water (H2O)–acetonitrile (ACN). The solubility was measured in the temperature range of 298.15–338.15 K, whereas the density was measured in the temperature range of 298.15–328.15 K. The electrolyte nonrandom two liquid (eNRTL) activity coefficient model is applied to model the solubility of NaOAc in water and in H2O–ACN. The model satisfactorily reproduces the solubility of NaOAc in water with two types of polymorphs: NaOAc anhydrous and NaOAc trihydrate. Although the eNRTL model also adequately represents the NaOAc solubility in H2O–ACN, the modeling results in terms of polymorphs need further experimental verification. The Clarke molar volume model is applied to model the solution density of the NaOAc–H2O and NaOAc–H2O–ACN. The model result showed excellent agreement with the data. The average absolute relative deviation between the model result and the data is 0.16% for the NaOAc–H2O system and 1.16% for the NaOAc–H2O–ACN system.
期刊介绍：
The Journal of Chemical & Engineering Data is a monthly journal devoted to the publication of data obtained from both experiment and computation, which are viewed as complementary. It is the only American Chemical Society journal primarily concerned with articles containing data on the phase behavior and the physical, thermodynamic, and transport properties of well-defined materials, including complex mixtures of known compositions. While environmental and biological samples are of interest, their compositions must be known and reproducible. As a result, adsorption on natural product materials does not generally fit within the scope of Journal of Chemical & Engineering Data.
