00925njm 22002777a 4500 dc Concepción Rodríguez, Eduardo Iván author Gómez Hernández, Ángel author Martín González, María del Carmen author Segovia Puras, José Juan author 2017 In this paper, density and viscosity measurements at pressures up to 140 MPa are presented in a temperatura range from (293.15 to 393.15) K for diethanolamine (DEA) + water, triethanolamine (TEA) + wáter 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. J. Chem.
