 1827.    KOCH, H., AND HORN, O.  [Comparative Investigation of Motor Behavior of a Synthetic Naphtha (Kogasin I) by Fischer-Tropsch and a Petroleum Naphtha.]  Brennstoff-Chem., vol. 13, 1932, pp. 164-167; Ges. Abhandl. Kenntnis Kohle, vol. 11, 1934, pp. 530-536; Chem. Abs., vol. 26, 1932, p. 3657.

        Various 10° fractions of the 2 naphthas have been examined and compared for density, unsaturated hydrocarbons, I number, C₆H₆ number and octane number.  With increasing boiling point of the fractions, unsaturated hydrocarbons decrease from 46-23% in the synthetic product but increase from 16.5-29% with the petroleum fuel.  Antiknock rating decreases from 85-41.5 octane no. with the synthetic, and from 77-54.5 with the petroleum fuel.
