Aah. Padua et al., DENSITY AND VISCOSITY MEASUREMENTS OF 2,2,4-TRIMETHYLPENTANE (ISOOCTANE) FROM 198 K TO 348 K AND UP TO 100 MPA, Journal of chemical and engineering data, 41(6), 1996, pp. 1488-1494
New density and viscosity results for 2,2,4-trimethylpentane at temper
atures from 198 K to 348 K and pressures up to 100 MPa are reported. T
he measurements of both properties were performed simultaneously using
a vibrating-wire instrument operated in the forced mode of oscillatio
n. The present set of measurements extends those found in the literatu
re to the high-pressure and low-temperature region. Correlations for b
oth the density and the viscosity are presented, and comparisons are e
stablished with various sets of results from the literature. The estim
ated uncertainties of the results are +/-0.05% for the density and +/-
2.5% for the viscosity.
