       Relation of viscosity to temperature of lubricants prepared from chlorinated Kogasin condensed with xylene has been improved by increasing the paraffin content.  Lubricants possessing properties of paraffin-base oils were obtained in the treatment of Kogasin of Cl content averaging 1-2 atoms with activated Al without the addition of aromatic hydrocarbons.  Olefin hydrocarbons in synthetic benzine were polymerized to lubricants by H₂O-free AlCl₃, their viscosity depending on the boiling point of the original material.  The synthetic lubricants correspond with the best petroleum products in stability toward oxidation, coking residue, and behavior at low temperatures.
