Salting-Out of n-Propyl Alcohol with Potassium Nitrate from Aqueous Solutions

Salting-Out of n-Propyl Alcohol with Potassium Nitrate from Aqueous Solutions The solubility of components and critical phenomena in the ternary system constituted by potassium nitrate, water, and n-propyl alcohol were studied by the visual polythermal method in the temperature range 25–80°C. The temperature of formaiton of the critical node of the monotectic equilibrium (critical solution-solid phase) and the solution compositions corresponding to the critical solution points at different temperatures were determined. The isothermal solubility diagrams of the system were constructed and the distribution coefficients of n-propyl alcohol at different temperatures were calculated. A comparative analysis of the salting-out effect exerted by potassium nitrate on aqueous solutions of n-propyl alcohol and isopropyl alcohol was done. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Applied Chemistry Springer Journals

Abstract

The solubility of components and critical phenomena in the ternary system constituted by potassium nitrate, water, and n-propyl alcohol were studied by the visual polythermal method in the temperature range 25–80°C. The temperature of formaiton of the critical node of the monotectic equilibrium (critical solution-solid phase) and the solution compositions corresponding to the critical solution points at different temperatures were determined. The isothermal solubility diagrams of the system were constructed and the distribution coefficients of n-propyl alcohol at different temperatures were calculated. A comparative analysis of the salting-out effect exerted by potassium nitrate on aqueous solutions of n-propyl alcohol and isopropyl alcohol was done.
