Abstract

PURPOSE: The titled lubricating oil with excellent traction characteristics, oxidation stability and corrosion resistance, prepd. by using a specified naphthenic hydrocarbon compd.
CONSTITUTION: After separation from a Friedel-Crafts catalyst and an unreacted material, a reaction product obtd. by reacting 1mol of an (alkyl-substd.) biphenyl with 1mol or less of an (alkyl-substd.) benzyl halide in the presence of the Friedel-Crafts catalyst at a temp. above the m.p. of the biphenyl but below 180°C under pressure of 1W50kg/cm2G is hydrogenated with introduction of at least 9mol of hydrogen per mol of the reaction product in the presence of a hydrogenation catalyst at 100W200°C under hydrogen pressure of 10W200kg/cm2G, to obtain a lubricating oil for power transmission means consisting of a naphthenic hydrocarbon compd. of the formula (wherein R1 is 1W3C alkylene; R3W5 are each 1W4C alkyl; l, m and n are each 0W3) having three hydrogenated, six- membered carbon rings.
