Claims12
A traction fluid composition which is the product obtained by hydrogenation of a hydrocarbon composition containing at least 40 weight percent diphenylalkanes said diphenylalkanes being represented by the formula ##STR2## wherein x, y and z are integers in the range of 0 to 14, with the sum of x, y and z being in the range of 6 to 18, said diphenylalkanes being characterized further in that x and z are 0 in at least 5 weight percent thereof, the remaining hydrocarbons in said composition having a boiling range similar to the diphenylalkanes, said hydrocarbon composition having a boiling range of about 300.degree. to 450.degree. C. at atmospheric pressure.
A method of operating a tractive device wherein torque is transmitted between relatively rotatable members having tractive surfaces in a torque transmitting relationship and having a tractant disposed on said tractive surfaces, said method being characterized in that said tractant comprises the product obtained by hydrogenation of a hydrocarbon composition containing at least 40 weight percent diphenylalkanes, said diphenylalkanes being represented by the formula ##STR3## wherein x, y and z are integers in the range of 0 to 14, with the sum of x, y and z being in the range of 6 to 18, said diphenylalkanes being characterized further in that x and z are 0 in at least 5 weight percent thereof, the remaining hydrocarbons in said composition having a boiling range similar to the diphenylalkanes, said hydrocarbon composition having a boiling range of about 300.degree. to about 450.degree. C. at atmospheric pressure.
