چکیده انگلیسی


• Vapor pressure of aqueous methyldiethanolamine (MDEA) mixed with various concentrations of 1-butyl-3-methyl-imidazolium tetrafluoroborate ([bmim][BF4]) and 1-butyl-3-methyl-imidazoliumdicyanamide ([bmim][DCA]) have been measured and compared with conventional solvents.
• A standard response surface methodology (RSM) design, namely central composite design has been applied in this work to investigate the effects of temperature and concentration of Piperazine, [bmim][BF4] and [bmim][DCA] on the vapor pressure of aqueous 4 kmol m−3 MDEA.
• The experimental values of the responses are in good agreement with the values predicted by the models.

Vapor pressure of aqueous methyldiethanolamine (MDEA) mixed with various concentrations of 1-butyl-3-methyl-imidazolium tetrafluoroborate ([bmim][BF4]) and 1-butyl-3-methyl-imidazoliumdicyanamide ([bmim][DCA]) have been measured and compared with conventional solvents.A standard response surface methodology (RSM) design, namely central composite design (CCD) has been applied in this work to investigate the effects of temperature and concentration of Piperazine, [bmim][BF4] and [bmim][DCA] on the vapor pressure of aqueous 4 kmol m−3 MDEA.The vapor pressure data of aqueous 4 kmol m−3 MDEA mixed with ionic liquids ranging from 0 to 2.0 kmol m−3 and temperatures ranging from 30 to 80 °C, showed that the ionic liquids reduced the vapor pressure of solvents with the order of [bmim][DCA] > [bmim][BF4].The experimental values are in good agreement with the values predicted by the models. The model results showed that the quadratic model was suitable and sufficient for predicting the vapor pressure of solutions in the investigated ranges of temperature and concentration.
