 1814.    ---------------.  [KOCH, H.]  [Alkylation of Aliphatic Hydrocarbons, Particularly With Regard to Kogasin.]  Reichsamt Wirtschaftsausbau, Prüf-Nr. 102, 1940, pp. 49-57; PB 52,004; Chem. Abs., vol. 41, 1947, p. 6698.

       By alkylation in the presence of anhydrous HF the products of Kogasin (heavy oil from the Fischer-Tropsch process) synthesis can be converted into high-antiknock fuels similar to isooctane.  The HF catalyst gives few side reactions, has a long life, and when activated by BF₃, also can be used for the conversion of C₂H₄ or ethylenic mixtures.  Fractions of Kogasin not useful elsewhere are either isomerized and split with AlCl₃ or pyrolized, to give an olefin mixture suitable for the alkylation reaction.
