This paper is the second part concerning the study of the solubility of aromatics in aqueous alkanolamine solutions. Vapor pressures over (liquid + liquid) mixtures and toluene solubility data are reported herein for toluene with pure water and aqueous alkanolamine solutions: monoethanolamine (MEA), diethanolamine (DEA), methyldiethanolamine (MDEA), and diglycolamineo (DGA). Modelling of solubility data are achieved using a simple model based on activity coefficients. (c) 2006 Elsevier Ltd. All rights reserved.
