ABSTRACT
2-Butanol is an alcohol which can be from renewable origin, and it is clasiffied as second-generation biofuels. Before the implementation of some biofuels, thermophysical and thermodynamic properties are required. To fulfil this objective, dynamic viscosities of (2-butanol + 2,2,4-trimethylpentane) and (2-butanol + 1,2,4-trimethylbenzene) mixtures are reported at four temperatures (293.15, 313.15, 333.15, 353.15) K, pressures up to 140 MPa and mole fractions of 2-butanol x = (0.3, 0.5, 0.8, 1). The measurements were carried out using an accurate vibrating-wire viscometer with a relative expanded uncertainty of 1.5% for a coverage factor k = 2. Experimental data were fitted to a modified VFT model obtaining good results in agreement with the uncertainty.
