original pycnometers for volatile liquid density over wide ranges of temperature and pressure practical example
Metrologia, 2014Co-Authors: Salvatore Lorefice, Raffaella Romeo, Marco Santiano, Andrea CapelliAbstract:A novel kind of pycnometer was designed for liquid density measurements suitable to be used over wide ranges of temperature and pressure. Two similar pycnometers have been manufactured and tested with n-Nonane 99.7 mol% in the temperature range from 233 K to 313 K at pressure lower than 10 MPa. To validate the procedure, the experimental values of density of an n-Nonane sample have been compared with the density values given in the literature by means of the En number. The density uncertainty of n-Nonane is found to be 0.16 kg m−3 (0.02%) in the temperature range from 253 K to 313 K and lower than 0.07% between 233 K and 243 K over the whole pressure range tested.

Isobaric Vapor-Liquid Equilibria of the Ternary System 1-Pentanol + Nonane + Anisole
Journal of Chemical & Engineering Data, 2008Co-Authors: Helle Kirss, M. Kuus, Enn SiimerAbstract:Isobaric vapor–liquid equilibria (VLE) were measured for the ternary system 1-pentanol + Nonane + anisole and for two constituent binaries, Nonane + anisole and 1-pentanol + anisole, at the pressur...

Excess enthalpies of pentyl ethanoate—1-hexanol, pentyl ethanoate—n-Nonane and pentyl ethanoate—1-hexanol—n-Nonane at 298.15 K
Thermochimica Acta, 1994Co-Authors: L. Kudryavtseva, M. Kuus, Enn SiimerAbstract:Abstract Excess enthalpies for pentyl ethanoate—1-hexanol, pentyl ethanoate— n -Nonane and pentyl ethanoate—1-hexanol— n -Nonane mixtures at 298.15 K have been determined with a Calvet-type microcalorimeter. The unifac group contribution model fitted to binary H E data and several modified Redlich—Kister equations have been applied to predicting ternary excess enthalpies. The predicted results agree satisfactorily with the experimental values.

Excess enthalpies of 1-nonene−n-Nonane, 1-hexanol−2-hexyn-1-ol, 1-nonene−2-hexyn-1-ol−n-Nonane, and 1-hexanol−2-hexyn-1-ol−n-Nonane at 298.15 K
Thermochimica Acta, 1994Co-Authors: L. Kudryavtseva, Enn SiimerAbstract:Abstract Excess enthalpies for the two binary systems, 1-nonene- n -Nonane and 1-hexanol-2-hexyn-1-ol, and the two ternary systems, n -Nonane-1-hexanol-n-Nonane and 1-hexanol-2-hexyn-1-ol- n -Nonane, at 298.15 K have been determined with a Calvet-type microcalorimeter. The experimental results of the binary systems have been fitted to Redlich-Kister equations. Some modified Redlich-Kister equations and the unifac group contribution model have been applied in predicting ternary excess enthalpies.

Isobaric Vapor−Liquid Equilibria of the Ternary System Methylbutyl Ketone + 1-Pentanol + Nonane
Journal of Chemical & Engineering Data, 2006Co-Authors: Helle Kirss, And Enn Siimer, M. KuusAbstract:Isobaric vapor−liquid equilibria (VLE) were determined for the ternary system methylbutyl ketone + 1-pentanol + Nonane and for the binaries methylbutyl ketone + 1-pentanol and 1-pentanol + Nonane. Measurements were made in a semi-microebulliometer at the pressures of (26.66, 53.33, and 79.99) kPa. A minimum boiling azeotrope was observed in the 1-pentanol + Nonane system. The Wilson and modified Wilson models were used to correlate the binary VLE data. The VLE data of the ternary system were predicted by the modified Wilson model.
