Lc. Wilson et al., CRITICAL-POINT MEASUREMENTS BY A NEW FLOW METHOD TRADITIONAL STATIC METHOD, Journal of chemical and engineering data, 40(4), 1995, pp. 765-768
A new flow method and a traditional static method have been employed t
o obtain the critical temperatures and pressures for 11 compounds: 1,1
-dimethylpropyl methyl ether, 1,1-dimethylethyl ethyl ether, toluene,
ethylbenzene, (1-methylethyl)benzene, 1-methylethyl ethanoate, 2-penta
none, 2-hexanone, 2-heptanone, hexafluoroethane, and propene. Accurate
critical densities were also obtained using a static method. The crit
ical properties of stable compounds appear to be accurately determined
by both methods. The flow method allows the determination of accurate
critical properties for more reactive or thermally unstable compounds
