We extended the oil compatibility model to the dissolution of asphaltenes (Asps) in maltenes from 10 crude oils (COs). As scales for the power of solvents of interest, vide infra, we used solvatochromic parameters, calculated from the UV-vis spectra of solvatochromic compounds (probes), Hildebrand/Hansen solubility parameters, and the colloidal instability index of COs. As the colors of maltenes or asphaltene-free crude oils CO(Asp-free) were too dark to permit recording the absorption spectra of the probes, we formulated models for these fractions (MCO(Asp-free). They were composed of low molar mass hydrocarbons, namely, cis and trans decalines, isooctane, 1-methylnaphthalene and, as model for resins, benzothiazole/n-octyl-l-naphthoate. We based formulations of these MCO(Asp-free) on SARA analysis of the COs and elemental analysis of the corresponding resins. We validated MCO(Asp-free) as models for the corresponding CO(Asp-free) by showing that the correlation between Hildebrand solubility parameter (delta(t)) of (COs) and delta t for MCO(Asp-free) is linear with a slope close to unity. Regarding Asp dissolution, we show that the correlations between log(dissolved Asp, mass %) and each of the following solvent descriptors is linear: empirical polarity of MCOs(Asp-free); delta(t) of COs; colloidal instability index of COs. Furthermore, the multiple correlation between log(dissolved Asp, mass %) and other solvatochromic parameters showed that solvent dipolarity and polarizability are important factors for Asp dissolution, in agreement with our previous results on Asp dissolution in pure solvents. The formulation of a model that successfully mimics maltenes is potentially very useful, e.g., in rationalizing the efficiency of certain classes of additives employed for Asp stabilization.
