1052. HIBSHMAN, H. J.AND DOLPH, R. N. (Standard Oil Development Co.). Process for Segregating Oxygenated Hydrocarbons. United States Patent 2,542,521, Feb. 20, 1951; appl. filed Aug. 6, 1948, Serial No. 42,818; 5 claims (Cl. 260-450). Chem. Abs., vol. 45, 1951, p. 4431.

Process consists of contacting a mixture of hydrocarbons with silica gel at the top of a vertical tower, so that the oxygenated compounds will be adsorbed onto the gel and the mass will move downward into the lower part of the tower where it comes into contact with a C₁-C₄ alcohol, which acts as a desorbent for most of the oxygenated compounds except the acidic one. The desorbed oxygenated compounds are removed as a side stream from the tower, the acidic oxygenated compounds form the bottom, and the fraction of hydrocarbons, which have not been adsorbed, from the top of the tower. 1 literature ref. and 3 United States patens cited.
