1020.    ---------------.  [Some Properties of the Synthetic Petroleum Hydrocarbons Prepared From Carbon Monoxide at Ordinary Pressure.]  Ber. Deut. Chem. Gesell., vol. 59B, 1926, pp. 923-925; Chem. Abs., vol. 20, 1926, p. 2815.

        The gas-oil fraction contains C₂H₆, C₃H₈, and C₄H₁₀; the corresponding olefins are present in only very subordinate amounts.  The benzine, isolated by adsorption with active charcoal and distillation with steam, is H₂O-clear, stable to light, has a pleasant odor, does not turn yellow or resinify on standing for months, d.₄¹⁵ 0.6718, upper heat value 11,360 cal. per gm., ignition temperature in O₂ 335°, b. p. 2.4 vol. % up to 40°, 96.4% up to 180°, d₄²⁰ from 0.6367 for the 20°-55° fraction to 0.7264 for the 120°-180° fraction, C and H₂ for the same fractions 84.23, 16.50, and 83.35, 14.96%, respectively, upper heat value of the 75°-120° fraction 11.495 cal. per gm.  The petroleum fraction, d₄²⁰ 0.7804, b. p. 4.4 vol. % 170°-180°, 83.2% up to 330°, d₄²⁰, C and H₂ for the 170°-270° fraction (58.4 wt. % of the total) 0.7646, 85.04%, 14.94% (heat value 11.225 cal. per gm.), for the 270°-330° fraction (24.1%) 0.7972, 85.36, 14.41.  The paraffin fraction freed from adhering paraffin oil with Me₂CO is colorless, odorless, solidifies at 61°, and has a C content of 84.57% and H of 14.57%.  The synthetics differ from the natural products in that they require no refining and are wholly free of S compounds.
