        Attempt to produce lubricating oil by polymerizing unsaturated hydrocarbons in Kogasin (I) by applying pressure.  A (I) fraction (b. 50°-250°) in a Pb- or Zn-plated Pb tube was compressed to 5,000 kg. per cm.² and 11,700 kg. per cm.² for 1-5 hr., and the change in n was noted.  Inconclusive results were obtained.  Experiments using the Pt tubes are suggested as likely to yield more precise data.
