2964. --------. [Lubricating Oils.] Italian Patent 389,688, July 9, 1941, in Germany Sept. 9, 1940. Ocl u. Kohle, vol. 39, 1943, Sch. 193; Chem. Zentralb., 1943, I, p. 591.

Hydrocarbons obtained from water gas by the Fischer-Tropsch process b. above 150º and preferably above 280º are condensed with AlCl₃. It is advantageous to make use of oils that have been obtained by working with Co catalysts with a high content of inert material and with recycling of a synthesis gas with a ratio of fresh gas to recycle gas of 1 : 3 or 1 : 5. The lubricating oil has a very low viscosity pole height, 1.75-1.48, and a very low congealing point, about -30º.
