Solubility

By testing the determination of the Gilsonite solubility, the pure Gilsonite can be obtained by using certain solvents, in such a way that Gilsonite is dissolved in the solvent, the Gilsonite is dissolved and the impurity remains.
The solvents used for this work, as well as the type of testing they have been listed below:

  1. Carbondisulfide (cs2) by testing ASTM D4.

    2. Carbon tetrachloride (ccl4) by testing ASTM D3467.

    3. Trichloroethylene (TCE) by testing ASTM D2042.
