摘要：

Hydrotropic solutions can be used in separation of two isomers as hydrotropes at high concentrations can enhance solubilities of these isomers in aqueous solution differently. Solubility data are determined for o and p chloronitrobenzenes (CNBs) in aqueous solutions of sodium butyl monoglycol sulphate (NaBMGS). o CNB is highly solubilized as compared to p CNB and can be precipitated out selectively on dilution with water at a reasonable recovery. Precipitation kinetics of p CNB determined from a solvent capacity varying batch crystallizer using the method of s plane analysis show that the relative order with respect to linear growth rate in conventional power law relative nucleation correlation is near unity. © 1991, Taylor & Francis Group, LLC.
