Volumetric measurements of the liquid fluorinated ethers CHF2OCH2CF3and CHF2OCHFCF3at temperatures from 278.15 K to 338.13 K and pressures from 0.1 MPa to 380 MPa

PVT Property Measurements for Liquid 1,2-Dichloro-1,2,2-trifluoroethane from 278 to 338 K

“…This work is part of an experimental program to determine the contributions of the various substituents to the volumetric properties of substituted ethanes. The overall aim is to explore the limitations of a simple scheme for predicting the volumetric properties of a series of related compounds (Malhotra and Woolf, 1995). The present results complement the earlier data (Malhotra and Woolf, 1993a) for 2,2-dichloro-1,1,1-trifluoroethane (R123), for which the normal boiling point of 300.7 K is 2 K lower than that of R123a (Kubota et al, 1989).…”

Volumetric measurements of liquid pentan-2-one, hexan-2-one, and 4-methylpentan-2-one at temperatures from 278.15 K to 338.13 K and pressures in the range from 0.1 MPa to 386 MPa

“…The reproducibility in the densities was within 20.002 kg·m −3 , and their accuracy was estimated to be within 20.02 kg·m −3 . The volume ratios were measured using a bellows volumometer (described in detail elsewhere (5) and with essential features summarized recently (6) ). Measurements were made at the ITS-90 temperatures (278.15, 288.15, 298.14, 313.14, 323.14, and 338.13) K for the pressure range from 2.5 MPa to the lower of either 386 MPa or below the estimated freezing pressure at the temperature of measurement.…”
