ABSTRACT
Recently, we have published the solubility data of ethane and propane in aqueous diethanolamine (DEA) and methyldiethanolamine (MDEA) solutions at different concentrations (Mokraoui et al., J. Chem. Eng. Data 2013, 58, 2100 2109). In this work, new measurements are provided for longer aliphatic light hydrocarbons, namely, isobutane, n-butane, n-pentane, and n-hexane. The same concentrations of alkanolamines (wDEA = 0.35, wMDEA = 0.25, and wMDEA = 0.50) have been considered in three phases coexisting conditions. MDEA has shown more affinity than DEA for a given weight-based concentration. Within the temperature window explored in this paper (293 353) K, the solubility increases with the amine concentration but it decreases with an increase in the hydrocarbon molecular size. Furthermore, the higher is the carbon atom number of the hydrocarbon, the smaller is the solubility dependence with temperature.
