A process for increasing mobility of heavy oil includes: disposing a solvating composition comprising a paraffinic solvent and a multifunctional solvent in a heavy oil environment including a heavy oil, the heavy oil comprising asphaltene; contacting the heavy oil with the solvating composition; and stabilizing asphaltene in the heavy oil with the solvating composition to increase mobility of the heavy oil and to form a stabilized heavy oil which includes the heavy oil and solvating composition. A method for making stabilized heavy oil includes separating resin from an oil; combining the resin and a paraffinic solvent to form a solvating composition; disposing the solvating composition in a heavy oil environment which includes heavy oil comprising asphaltene; and contacting the asphaltene with the solvating composition to make stabilized heavy oil, wherein the stabilized heavy oil comprises the solvating composition and heavy oil.

The first examples of Room Temperature Ionic Liquids (RTIL) containing fused polycyclic N-alkylisoquinolinium cations ([Cnisoq]+) in combination with the bis(perfluoroethylsulfonyl)imide anion ([BETI]â) have been synthesized, characterized, and utilized in liquidâliquid partitioning from water; these salts have unexpectedly low melting points and give high distribution ratios for aromatic solutes, especially chlorobenzenes, between the RTIL and water.
