       Series of chlorination products has been prepared from the olefin-containing gas-oil fraction, Kogasin II, obtained in the benzine synthesis from CO and H₂.  They were condensed with a number of aromatic hydrocarbons by using AlCl₃.  Best yields were obtained with the trichloro and tetrachloro compounds and xylene.  The oils resembled napthene-base oils in properties.  Catalytic hydrogenation gives a water-white oil of low specific gravity, high stability against oxidation, and small carbon residue, which retains its lubrication value at low temperature.  Comparative physical data are given for the various oils prepared.  Bibliography.
