1069. ------ [HODGES, L. P.] (Standard Oil Development Co.). Separation of Oxygenated Organic Compounds From Synthetic Naphtha. United States Patent 2,584,269, Feb. 5, 1952; appl. filed Oct. 25, 1948, Serial No. 56,448; 4 claims (Cl. 260-45).

Crude naphtha containing approximately 20 wt. % oxygenated organic compounds, including ketones, aldehydes, carboxylic acids, and esters, and obtained from the synthesis of CO and H₂ over an Fe catalyst is freed from these compounds by mixing the hydrocarbon fraction thereof with about 5-30 vol. % of a treating reagent comprising solvent extract of a lubricating-oil fraction, an alkali metal naphthenate, and an alkali metal hydroxide. The reagent may consist of 90-99% by weight of a hydrocarbon fraction b. above 600° F., 1-10% of Na naphthenate, and 10-50% of NaOH. The mixture thus prepared is distilled and a fraction obtained boiling in the range of gasoline substantially free of oxygenated organic compounds.
