“…[119] The most useful viscosity estimation methods for complex molecules have been reported based on group contributions (e.g., the Orrick-Erbar method, [120] the Sastry-Rao method, [121] and the UNIFAC-VISCO method [122]), the corresponding states concept (e.g., Przezdziecki and Sridhar, [123] Chatterjee and Vasant, [124] Teja and Rice, [125] and Queimada et al [126]) or the corresponding-states group-contribution (CSGC) method (e.g., Yinghua et al [127]). Group contribution methods for the estimation of liquid viscosity usually employ some variation of temperature dependence proposed by de Guzman, [128] …”
