saturated liquid molar volumes. Rackett equation

Isobaric VLE at 0.6MPa for binary systems Isobutyl Acetate+Ethanol, +1-Propanol or +2-Propanol

“…For this reason, the calculation programs used to verify the point-to-point test were prepared considering the Fortran program of Fredenslund et al [2], that [16] procedure and a modification [22,23] of the Rackett equation [24] (HR), and also the procedure of Tsonopoulos [21] (with k ij = 0.05 as mixing parameter) and the routines of Yen-Woods [17] (TY) or Rackket modified [22][23][24] (TR). The mentioned calculation programs have been previously applied in different systems [12][13][14], and no significant differences have been found between them, irrespective of the different operating pressures.…”

Standardization of chemical shifts of TMS and solvent signals in NMR solvents

“…25 A 1% error in density and hence susceptibility would lead to a 0.03 ppm error at temperatures far from the standard 25°C. However, for compounds that are not highly polar (such as acetone, chloroform, DMSO and tetrahydrofuran (THF)) the average error is 0.2 26 to 0.3%, 27 which would lead to a chemical shift error of 0.006 to 0.009 ppm at extreme temperatures. For D 2 O, the Kell equation 11 was used instead of the Rackett equation 10 to improve accuracy.…”

Technical equation of state models for heat transfer fluids made of biphenyl and diphenyl ether and their mixtures

“…This deficiency was already stated by Poling et al [12] for substances with a compressibility factor Z c < 0.22, but it is observed also for biphenyl (Z c = 0.261) and for diphenyl ether (Z c = 0.255). As the critical densities for both biphenyl and diphenyl ether are available with a reasonable accuracy, better accuracy for the estimation of the saturated liquid densities can be attained by using the modified Racket equation of Yamada and Gunn [52], as recommended in Ref. [12].…”
