1604. JACQUE, L., GIVAUDON, J., SCHMITT, P., AND DELION, R. [Preparation of Pure Paraffin Hydrocarbons by the Superfractionation of Synthetic Gasoline.] Rev. Inst. Franc. Petrol. et Ann. Combust. Liquides, vol. 1, December 1946, pp. 137-140; Chem. Abs., vol. 42, 1948, p. 4325.

By superfractionating a hydrogenated synthetic Fischer gasoline, the authors have prepared fractions of pentane, hexane, heptane, octane, and nonane, which analyze 8-9%, 22-23%, 20-25%, 20-22%, 10-15% of gasoline, respectively. The utilization of hexane for precipitating the asphaltic substances of lubricating oils and that of heptane as standard motor fuel for determining the octane numbers with the Cooperative Fuel Research motor is shown.
