2062. LINN, N. F. (Standard Oil Development Co.). Method of Producing Toluene. United States Patent 2,405,660, Aug. 13, 1946; appl. filed Oct. 17, 1942.

A hydrocarbon product from the hydrogenation of CO is fractionated into a naphtha fraction and a gas-oil fraction. The latter is cracked at 825°-925° F. in the presence of a catalyst. A fraction b. 210°-250° F. is recovered and combined with the naphtha fraction. The combined fractions are reformed at 850°-1,000° F. under 100-400 p. s. i. pressure in the presence of H₂ and of a catalyst containing an oxide of a group VI metal. A fraction b. 210°-250° F. is recovered, and the aromatics are separated by solvent extraction, followed by treatment of the extract with a paraffinic hydrocarbon such as C₅H₁₂.
