Physicochemical Properties of Phosphate Extracts and Mutual Solubility of Phases in the Extraction System with Monofunctional Aliphatic Alcohols

摘要

The main physicochemical properties of the extracts, such as density, viscosity, and conductivity, as well as the mutual solubility of the phases in the ROH-H_2O and ROH-H_2O-H_3PO_4 extraction systems, where ROH (R = C_5-C_(10)) stands for higher monofunctional aliphatic alcohols with a different length and structure of the hydrocarbon radical, have been studied in water and aqueous solutions containing phosphoric acid. The properties correlate with the length and structure of the hydrocarbon chain in the aliphatic alcohols, as well as with the concentration of mineral acid in the extracts.
