Fraction boiling below 100° of a Fischer-Tropsch synthetic benzine was separated into paraffins and olefins by means of Hg acetate, and the properties of narrow fractions of each series of hydrocarbons were determined. Some hydrocarbons of high purity were isolated. Various methods of determining the I value of olefins were compared. The Kaufmann and Gross-Getringhaus methods proved satisfactory. Monoolefins were polymerized with AlCl₃. _n-C₇H₁₆ proved a suitable chemically indifferent solvent for this purpose. The viscous oils obtained were compared with those obtained in the same manner from known olefins. The yield, viscosity, and pole height of the lubricating oils (mostly high-grade) depend on the structure of the olefins and particularly on the position of the double linking, for example, tertiary olefins yield oils with poor pole heights. Results are presented in tables and curves.
