摘要：
Densities and speeds of sound in the temperature interval (278.15 to 318.15) K and heat capacities per unit volume from (283.15 to 318.15) K were determined for the dodecane + 1-butanol and + 2-butanol systems. Measurements were made over the whole composition range and at atmospheric pressure. From these data, excess molar volumes, excess isentropic compressibilities, and excess isobaric molar heat capacities were calculated. Results were critically compared with literature data of systems containing these butanol isomers. Differences between both systems were ascribed to the different association ability of the two alcohols.
