A method of obtaining vanadyl porphyrins by acetone treatment of asphaltite was proposed. A 1 gram asphaltite sample and 200 ml of acetone were placed in a flask and refluxed by 1 hour. After cooling, the solution was filtered and the content of vanadyl porphyrins in the acetone extract was determined by a spectrophotometer. The product was obtained in crystalline form after the solvent was driven off. Tests show that use of acetone resulted in a more complete extraction of the porphyrins than can be obtained by ordinary alcohol-acetone or alcohol extraction methods.
