The current study is a step toward developing an approach with improved extrapolation capability and predictive potential in modeling viscosities. A modified Yarranton-Satyro correlation that relates viscosities to densities was coupled with SAFT + Cubic EoS. Having three adjustable parameters, the proposed method allows nearly precise extrapolations of the light gases viscosities to the extreme pressure conditions (up to 鈭? GPa) in wide temperature range. The predictive potential of the proposed method is remarkable as well. For example, using the parameters fitted to the data of carbon dioxide, it allows robust prediction of the elevated pressure viscosities of halocarbons such as R-134a and hexafluorobenzene. In addition, relying on the exptl. viscosity of just a single n-alkane, it usually yields reliable estimations of the data of not only n-alkane series but also heavy organic compounds, such as 2,6,10,15,19,23-hexamethyltetracosane, bis(2-ethylhexyl) phthalate, diisodecyl phthalate, and 2-ethylhexyl benzoate in a vast range of values (from single mPa路s to thousands of mPa路s). It was demonstrated that using a single set of parameters, the proposed approach can generate accurate predictions of viscosities in a wide pressure range for ionic liquids belonging to similar families, such as [Cxmim][PF6] and [Cxmim][BF4]. Densities of 1-hexyl-3-methylimidazolium hexafluorophosphate ([C6MIM][PF6]), 1-butyl-3-methylimidazolium tetrafluoroborate ([C4MIM][BF4]), and 1-methyl-3-octylimidazolium tetrafluoroborate ([C8MIM][BF4]). Exptl. data,69-71 points. Calculateddata: SAFT + Cubic, solid lines. Viscosities of 1-butyl-3-methylimidazolium hexafluorophosphate ([C4MIM][PF6]), 1-hexyl-3-methylimidazolium hexauorophosphate ([C6MIM][PF6]), and 1-methyl-3-octylimidazolium hexafluorophosphate ([C8MIM][PF6]). Exptl. data,71-73 points.Predicted data: YS, solid lines. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7HPLC of Formula: 5444-75-7).
2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.HPLC of Formula: 5444-75-7
