Vapor pressure measurements of aqueous N-methyldiethanolamine solutions

Abstract Xu, S., Qing, S., Zhen, Z., Zhang, C. and Carroll, J.J., 1991. Vapour pressure measurements of aqueous N -methyldiethanolamine solutions. Fluid Phase Equilibria , 67: 197-201. The vapor pressures of aqueous N -methyldiethanolamine (MDEA) solutions were measured using a modified ebulliometer. The concentration of MDEA ranged from 10 wt.% to 70 wt.% and temperatures from about 55°C to 108°C. The measured vapor pressures were compared with those predicted by Raoult's law. The maximum deviation between the predicted values and experiment is only 5.3 kPa.
