This paper presents a comprehensive study on the effect of citric acid, sodium benzoate, sodium salicylate and urea (hydrotropes) on the solubility and mass transfer coefficient for the extraction of ethyl benzoate in water. The influence of a wide range of hydrotrope concentrations (0-3.0 gmol dm(-3)) and different temperatures (303-333K) on the solubility of ethyl benzoate has been studied. The influence of different hydrotrope concentrations on the mass transfer coefficient for ethyl benzoate-water system has been ascertained. Setschenow constant, K-s, a measure of the effectiveness of hydrotrope has been determined for each case. The solubility of ethyl benzoate increases with the increase in hydrotrope concentration and also with system temperature. Consequent to the increase in the solubility of ethyl benzoate, the mass transfer coefficient was also found to increase with an increase in hydrotrope concentration, A Minimum Hydrotrope Concentration (C-min) was found essential to show a significant increase in the solubility and mass transfer coefficient for ethyl benzoate -water systems. The enhancement factor, which is the ratio of the value in the presence and absence of a hydrotrope is reported for both solubility and mass transfer coefficient.
