3169. SHERWOOD, P. W. Aldehydes From Hydrocarbons. Petrol. Processing, vol. 4, No. 7, 1949, pp. 794-800. Describes 2 processes for the manufacture of aldehydes directly from hydrocarbons. Partial oxidation of hydrocarbons can be made on the basis of formaldehyde and acetaldehyde production. The more recent Oxo process for the synthesis of aldehydes by the catalytic reaction of olefins with water gas, shows interesting potentialities for the manufacture of propionaldehyde, butyraldehyde, and valeraldehyde. At present, however, it s used only as a 1st step in the production of isooctyl and nonyl alcohols and other derivatives. By indirection, it can be used for the synthesis of an unlimited variety of aldehydes. Technical details of the oxidation and Oxo processes are described, and their possibilities and limitations are discussed briefly. German experience on the oxoation of olefins is summarized in describing the Italian Bambrini plant, which was designed by the I. G. Farbenindustrie but not constructed as planned. the economic prospects of the manufacture of aldehydes by the Oxo process are, at the present time, wholly a matter of speculation. |
