689. ------. [FISCHER, F., AND PICHLER, H.] (Hydrocarbon Synthesis Corp.). Solid Paraffin Products From Carbon Monoxide and Hydrogen. United States Patent 2,206,500, July 2, 1940; appl. filed July 16, 1937, Serial No. 153,924, in Germany Aug. 1, 1936; 6 claims (Cl. 260-449). Chem. Abs., vol. 34, 1940, p. 7295.

Describes apparatus and a process of producing paraffin products solid at ordinary temperature, which comprises treating CO with H₂ at 125º-250º under a pressure above 4 atm. in the presence of a solid catalyst containing Co as the main active ingredient coated with paraffin solid at room temperature, approximately 1 l., measured under atmospheric pressure and at room temperature, of the mixture of CO and H₂, being hourly brought into contact with the quantity of catalyst, which contains 1 gm. Co. and causing all but a thin coating of paraffin to drip off from the catalyst to prevent clogging of the cavities existing between the individual catalyst particles.
