Automated measuring device of (p, ρ, T) data: Application to the 1- hexanol+n -hexane system

Abstract

An entirely automated measuring device for (p, ρ, T) data based on the vibrating tube principle is detailed. The reliability of whole configuration is checked through measurement and later comparison with recommended literature data for the 1-hexanol+n-hexane binary system within the temperature and pressure ranges (278.15-333.15K) and (1-40MPa), respectively. Pressure and temperature dependencies of excess volumes and excess isothermal compressibilities obtained from primary data were analysed and qualitatively explained in terms of well-known microscopic effects. © 2003 Elsevier Science B.V.
