Abstract

PURPOSE:To prepare the title fluid having high viscosity at a high temperature and a high rolling coefficient of friction, from a low-cost raw material, by treating a specific fraction of a residue oil with an acid catalyst, and hydrogenating the treated oil. CONSTITUTION:A fraction obtained by the thermal cracking of petroleum hydrocarbons at >=700 deg.C, and containing mainly of a component having a boiling point of 150-195 deg.C and also containing a hydrocarbon mixture of unsaturated aromatic hydrocarbons having the above boiling temperature range, is heated at 0-200 deg.C in the liquid phase, in the presence of an acid catalyst, to convert the unsaturated aromatic constituents into heavy constituents. The reaction product thus produced has a boiling temperature range of 275-380 deg.C (reduced to 1atm). It is hydrogenated until the amount of the residual benzene rings becomes below 2mol%, to obtain the desired fluid having a boiling temperature range of 280-375 deg.C.
