962. HEINRICH, R. L. (Standard Oil Development Co.). Olefin Polymerization Feed Stock. United States Patent 2,570,032, Oct. 2, 1951; appl. June 23, 1948, Serial No. 34,832; 6 claims (Cl. 260-683.15). Chem. Abs., vol. 46, 1952, p. 1748.

Mixtures of olefins, hydrocarbons, and oxygenated organic compounds, such as the reaction products from a Fischer-Tropsch synthesis, are treated with H₂S, which contains a small amount of gaseous HCl as catalyst at 5º-120º for 1 min.-6 hr. The oxygenated compounds form high-boiling compounds which are readily separated from the olefins and other hydrocarbons. The olefin-containing fraction is suitable for polymerization with a Friedel-Krafts catalyst.
