Erdmann, E

A process for obtaining paraffin and highly viscous lubricating oils from crude bituminous tar comprises treating the crude bituminous tar in the cold state with acetone to form a solution, filtering off the paraffin which separates off from the solution, dissolving the paraffin in an indifferent solvent, treating the solution thus obtained with concentrated sulphuric acid, removing the acid resins and the sulphuric acid from the solution, and precipitating the paraffin from the solution by means of acetone.
