Abstract
Experimental values of the density and viscosity for aqueous solutions of three alkanolamines composed of 32.5 mass % N-methyldiethanolamine (MDEA) and 12.5 mass % diethanolamine (DEA) with 2, 4, 6, 8, and 10 mass % 2-amino-2-methyl-1-propanol (AMP) have been determined in the temperature range of (303.15 to 343.15) K. The experimental results of the density and viscosity are given as a function of both temperature and AMP concentration. In the range of temperature studied, the experimental density values of the aqueous blends of alkanolamines decrease as the AMP concentration increases while the viscosity values increase as the AMP concentration increases. Correlation equations were obtained to allow the calculation of density and viscosity for aqueous solutions of MDEA and DEA as a function of AMP concentration and temperature.
