Viscosity measurements of ortho-xylene, meta-xylene, para-xylene and ethylbenzene [PDF]
The Journal of Chemical Thermodynamics, 2016 Abstract 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 ...
