3702. ----- [STUDIEN-UND VERWERTUNGS-G. M. B. H.] [Synthetic Antiknock Fuel.] French Patent 792,021, Dec. 21, 1935. Chem. Abs., vol. 30, 1936, p. 4314.

Aliphatic hydrocarbons produced catalytically under ordinary pressure from CO and H₂ are treated to separate constituents b. up to 100°. The Monoolefins in the constituents having a higher b. p. are polymerized, for example, with AlCl₃ to form lubricating oils, and the residue is subjected to cracking to obtain an antiknock fuel.
