Title
Gibbs energy additivity approaches to QSPR in modeling of high pressure dynamic viscosity of FAME and biodiesel
Abstract
© 2016 Elsevier B.V. Viscosity is directly affected by both temperature and pressure. Accordingly, model which correlates dynamic viscosity of fatty acid methyl ester (FAME) and biodiesel to number of carbon atoms and number of double bonds of fatty acid is proposed. The model is derived from the law of Gibbs energy additivity and it is used for estimation of dynamic viscosities of FAME and biodiesel at different temperatures and pressures from its carbon numbers and number of double bonds. All the estimated viscosities agree well with the reported experimental values. The average absolute deviation (AAD) and Bias were 1.78% and 0.52%, respectively.
