      1037.  HEROLD, P., AND LANGHEINRICH, H.  (I. G. Farbenindustrie A. G.).  Organic Compounds Containing Oxygen by Reduction of Carbon Oxides With Hydrogen.  United States Patent 1,743,214, Jan. 14, 1930; appl. filed Nov. 8, 1927, No. 231,986.  Chem. Abs., vol. 24, 1930, p. 1389.

            Organic compounds containing O are obtained, either alone or in conjunction with hydrocarbons, by reducing oxides of C with H2 under diminished, ordinary, or slightly elevated pressure up to about 20 atm. and at an elevated temperature, if the operation be carried out <300°, the catalyst employed consisting of Fe containing small additions of alkalies or alkaline earths or compounds of the same having an alkaline reaction and being used alone or in conjunction with other substances, carriers or activating substances, for example, Cu.  The resulting products are partly solid and partly liquid and gaseous.  In contrast to the conditions in the production of hydrocarbons alone, less H2O and CO2 are formed, and merely traces of the lower members of the paraffin series of hydrocarbons are produced.  The solid products are yellow to yellowish brown and contain, besides white paraffin, m. about 65°, a brown, viscous resins containing O.  The liquid portions have a yellow-green to yellow-brown color and boil at approximately 40°-200°.  They, too, contain paraffins.  Their sp. gr. is 0.74-0.80 and their Br value about 0.25-0.45.  The H2O of condensation contains alcohol and, in addition to CO2, organic acids volatilizable by steam.  Gives examples.
