 1883.    ---------------.  [TSUNEOKA, S., MURATA, Y., AND MAKINO, S.]  Synthesis of Benzine From Carbon Monoxide and Hydrogen at Ordinary Pressure.  XLVII.  Composition of Starting Gases With New Iron Catalyst.  Jour. Soc. Chem. Ind. (Japan), vol. 42, suppl., 1939, pp. 107-112.  Sci. Papers Inst. Phys. Chem. Research (Tokyo), vol. 35, 1939, pp. 337-347; Chem. Abs., vol. 33, 1939, p. 4761.

        Tabular results are given for experiments with CO and H₂ in the following ratios: 4:1, 3:1, 2:1, 1:1 and 1:2.  With a catalyst consisting of Fe+25% Cu (by weight of Fe)+125% kieselguhr+3% K₂CO₃, highest gasoline yields resulted from an initial gas mixture ratio of CO:H₂=1:1-1:2.  An initial gas ratio of 1:2 was found most conducive to high yields with a catalyst comprising: Fe+5%Ni+25% Cu+125% kieselguhr+3% K₂CO₃.  The larger the CO content of the gas the greater the degree of unsaturation of the gasoline.  Excess H₂ produces no deleterious effects on the synthesis.  The gasoline resulting from the synthesis employing the new Fe catalysts is colorless and clear.  Water hinders the progress of the reaction. Volatility and degree of unsaturation increase with higher reaction temperatures.  H₂ reduction increases the activity of the catalysts.
