摘要：

Densities of the (water + 2-amino-2-methyl-1-propanol, AMP), (water + n-butyldiethanolamine, n-BDEA) and (water + n-propylethanolamine, n-PEA) mixtures have been measured over the full range of compositions at temperatures ranging from 298.15 to 353.15 K (except for pure AMP which is solid at 298.15 K). Results of these measurements have been used in calculating excess molar volumes of each system. The partial molar volumes and their derivatives with respect to temperature provide a basis for extending our understanding of molecular interactions in these (water + alkanolamine) systems.
