Effect of Hydrotropes on Solubility and Mass Transfer Coefficient of p-Nitrobenzoic Acid
D. Gnana Prakash, S. Thenesh Kumar and N. Nagendra Gandhi

Abstract:
The effect of various hydrotropes such as sodium benzoate, sodium salicylate and nicotinamide on the solubility and mass transfer coefficient of p-nitrobenzoic acid was investigated. The solubility studies were carried out under a wide range of hydrotrope concentrations 0 to 3.0 kmol m-3 and different system temperatures (303-333 K). It has been observed that the solubility and mass transfer coefficient of p-nitrobenzoic acid increases with increase in hydrotorpe concentration and also with system temperature. The maximum enhancement factor, which is the ratio of the value in the presence and absence of a hydrotrope, has been determined for all sets of experimentations. The effectiveness of hydrotropes was measured in terms of Setschenow constant Ks and reported for all hydrotropes used in this study.
