 1983.    KREULEN, D. J. W.  [Physical and Chemical Constants of Two Completely Hydrogenated Oils Prepared by the Fischer-Tropsch Gasoline Synthesis.]  Chem. Weekblad, vol. 35, 1938, pp. 410-411; Chem. Abs., vol. 32, 1938, pp. 7252.

        These lubricating oils differ markedly from natural petroleum products in that the aliphatic side chains are very much branched.  The molecular weights (774 and 457, d. 0.8580 and 0.8453) are different, but the molecular constitutions are parallel; in both cases the viscosity poleheights are identical, although the viscosity time indexes are different.  The Ubbelohde law that oils of the same origin have the same pole height is confirmed.
