A Study on Hydrotropy--Petroleum and Petrochemical Products

摘要

A comprehensive investigation of the solubility and mass transfer coefficient enhancement of benzene through hydrotropy has been undertaken. The solubility and mass transfer coefficient studies were carried out using hydrotropes such as citric acid, urea, nicotinamide, and sodium salicylate under a wide range of hydrotrope concentrations (0 to 3.0 mol/L) and different system temperatures (303 to 333 K). The effectiveness of hydrotropes was measured in terms of Setschenow constant KS and reported for all hydrotropes used in this study.
