The first part of this work presents experimental density data of aqueous 3-amino-1-propanol (3A1P) solutions at different compositions and temperatures of (293.15 to 353.15) K. It was found that densities decreased with increasing temperatures and were concentration dependent. Excess molar volumes of aqueous 3A1P were also established. Five different methods were compared for correlating density data of unloaded 3A1P solutions. In the second part of this work, densities of CO 2 -loaded solutions were measured at 0.1 and 0.5 mass fractions of 3A1P at increasing temperatures and CO 2 -loadings. Two different models were used to regress these experimental data. The suitability of these methods to represent densities of unloaded and CO 2 -loaded 3A1P solutions is evaluated.

This paper reports new viscosity data for unloaded and CO 2 -loaded aqueous 3-amino-1-propanol (3A1P) solutions. For the unloaded system, experiments were performed over the whole concentration range at temperatures between 298.15 and 373.15 K. In the case of a CO 2 -loaded system, measurements were performed at five different CO 2 -loadings ranging from 0.13 to 0.54 mol of CO 2 /mol of 3A1P at 0.30 and 0.50 3A1P mass fractions. The experimental data were also regressed using available methods from the literature.
