819. GLOSSY, A. R. (The Texas Co.). High-Antiknock Motor-Fuel Hydrocarbons. United States Patent 2,257,074. Sept. 23, 1941: appl. filed July 8, 1939. Serial No. 283,429: 4 claims (Cl. 196-10). Chem. Abs., vol. 36. 1942. p. 647.

Describes arrangement of apparatus and a process that involves catalytically converting a mixture of CO and H₂ to a synthetic hydrocarbon mixture composed mainly of hydrocarbons having from 1 to about 10 C atoms per molecule, composed largely of normal olefins including normal butylenes, and being comparatively free from aromatic and napthenic constituents, separating from this synthetic mixture gasoline hydrocarbons boiling up to about 390º F., having a relatively high content of normal butylenes and a relatively low content of isobutylene, and treating these gasoline hydrocarbons with a paraffin hydrocarbon fraction comprising isobutene in the presence of concentrated H₂SO₄ in the substantial absence of isobutylene and aromatic hydrocarbons, whereby isobutene is alkylated to produce normally liquid saturated hydrocarbons having a high antiknock value and boiling within the range for motor fuel.
