Solubility data for toluene in various aqueous alkanolamine solutions

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 diglycolamine® (DGA). Modelling of solubility data are achieved using a simple model based on activity coefficients.
