ABSTRACT

In this paper, density and viscosity measurements at pressures up to 140 MPa are presented in a temperature range from (293.15 to 393.15) K for diethanolamine (DEA) + water, triethanolamine (TEA) + water and 2-dimethylaminoethanol (DMAE) + water in amine weight concentrations from 10% to 40%. Densities were measured using a vibrating tube densimeter (Anton Paar DMA HPM) with an expanded uncertainty (k = 2) less than +-0.7 kg m 3. Viscosity measurements were obtained using a falling body viscometer which was calibrated with water and dodecane. The viscosity expanded uncertainty (k = 2) ranges from +-2.5% for the highest viscosity to +-3.2% for the lowest.
