This paper is continuation of the study concerning the solubility of aromatics in aqueous alkanolamine solutions. Vapour pressures of ethylbenzene and xylene over aqueous (liquid + liquid) mixtures are reported herein. Solubility data of ethylbenzene and xylene in pure water and solubility data of ethylbenzene in aqueous alkanolamine solutions {methyldiethanolamine (MDEA) + diglycolamine ® (DGA)} are also reported herein. Modelling of solubility data is achieved using a simple model based on activity coefficients.
