        By the end of the war, Germany had a well-developed synthetic-lubricating oil industry, which was rapidly expanding.  On a quantity basis the products obtained from natural petroleum resources predominated, but from a quality standpoint the synthetic production was of more importance.  The total production of lubricants in January 1944 was 70,000 tons per mo., of which about 12% were synthetic oils. The I. G. Farbenindustrie was obtaining 1,250 tons per mo. from the polymerization of C2H4 with AlCl3, while they, together with Rhenania Ossag, were producing 2,100 tons from olefins obtained from the cracking of petroleum and Fischer-Tropsch waxes.  In addition to these developments, Ruhrchemie was producing 1,500 tons from olefins obtained from Fischer-Tropsch gas oils and sweater oil from the manufacture of wax derived from the process.  Rheinpreussen was obtaining 300 tons by a method analogous to that for Paraflow production with chlorinated Kogasin from the Fischer-Tropsch process as the main raw material.  In addition, there were about 3,000 tons of lubricating oils being produced by brown-coal hydrogenation.  A very promising development, which had not come into production, was the use of the esters of fatty acids, particularly sebacic and adipic acids.  Extensive bibliography.
