Transport properties of nonelectrolyte liquid mixtures?V. Viscosity coefficients for binary mixtures of benzene plus alkanes at saturation pressure from 283 to 393 K

(p,ρ,T,x) and viscosity measurements of {x1n-heptane+(1−x1)n-octane} mixtures at high temperatures and high pressures

“…Dymond and Young [45,46] and Zeberg-Mikkelsen et al [47] successfully used this equation to describe the experimental viscosity data for hydrocarbon mixtures. In the present work, we applied equation (8) to the viscosity data for the {x 1 n-heptane + (1 À x 1 )n-octane} mixtures.…”

“…As figure 9 demonstrates, the Grunberg-Nissan constant is negative and monotonically decreases with increasing temperature. For mixtures with n-alkane n < 12 where n is the carbon number, the values of G are negative [45,46]. For the ideal mixtures, the values of the Grunberg-Nissan constant are zero (G = 0).…”

Reference Correlation of the Viscosity of Cyclohexane from the Triple Point to 700 K and up to 110 MPa

“…Based on these criteria, 15 datasets were considered primary data. Table 1 summarizes the primary data 81,84,88,[113][114][115][116]129,131,138,152,156,159,161,193 detailing the temperature and pressure ranges, the authors' claimed uncertainty and purity of the sample, and the technique employed to perform the measurements. Some of the authors have only quoted the precision of their data, rather than uncertainty, in which case we left the relevant entry in Table 1 blank.…”

“…Finally, the primary data set was supplemented with six sets of viscosity measurements 116,129,156,159,161,193 of liquid cyclohexane at atmospheric pressure covering the temperature range (283-348) K and one set of measurements 84 along the liquid saturation line covering the temperature range (283-393) K. In summary, 495 data points covering the temperature range (283-673) K and pressures up to 110 MPa measured in 14 different viscometers were used as the primary data for the development of the residual viscosity contribution.…”

Correlation and Prediction of Dense Fluid Transport Coefficients. VIII. Mixtures of Alkyl Benzenes with Other Hydrocarbons

“…In Table 1, the experimental measurements [12][13][14][15], T. Makita, Personal communication (1985), [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] used to compute the aforementioned equations for the parameters a i , b i , and C and the experimental temperature ranges and maximum pressures considered are shown. It should be noted that the maximum pressure shown in the table refers to the point above which deviations started to increase considerably, i.e., the correlation is valid up to the maximum pressure quoted in the table.…”
