چکیده انگلیسی


• Viscosities of o-xylene, m-xylene, p-xylene and ethylbenzene were measured using a vibrating-wire viscometer.
• The measurements cover a maximum temperature range of (253 to 373) K and pressure range of (0.1 to 35) MPa.
• The experimental data were correlated with the empirical Andrade–Tait equation.
• Comparisons between the present results and literature data were performed.

The compressed liquid viscosities of ortho-xylene, meta-xylene, para-xylene and ethylbenzene were measured using a vibrating-wire viscometer at different temperatures and pressures. The measurements were performed over the temperature ranges of (273 to 373) K for o-xylene and m-xylene, (293 to 373) K for p-xylene and (253 to 373) K for ethylbenzene, at pressures from (0.1 to 30) MPa, except for ethylbenzene for which the pressure range was up to 35 MPa. The combined expanded uncertainty of the reported viscosity is better than 2% with a confidence level of 0.95 (k = 2). The experimental data were correlated with the empirical Andrade–Tait equation which reproduced the results with the average absolute percentage deviations of (0.25, 0.15, 0.16 and 0.23)% for o-xylene, m-xylene, p-xylene and ethylbenzene, respectively. The present results are in good agreement with most of the literature values.
