Abstract

PURPOSE: A lubricating oil composition, usable for an internal combustion engine, having improved detergency, antioxidizing, anticorrosion properties and thermal stability, and comprising a small amount of a movel polyetherboron ashless detergent.
CONSTITUTION: A compound of formula I (R is ≥40C alkyl group, etc; R' is formula III when Z is N, and formula IV when Z is O; R" is formula V, etc.; R"' is 2W3C alkylene group; R4' is H, etc.; m is an integer 5W20; n is an integer 3W8; Y is alkyl group) or a polyalkenylsuccinic anhydride is treated with an N,N,N'-tris (polyoxyalkylene)alkyl-alkylenediamine to form an intermediate, which is treated with boric acid, etc. to give a compound of formula II. A small amount of the resulting compound is added to a base oil to form the objective lubricating oil composition. The compound of formula I is obtained by reacting a secondary alkanolamine with the intermediate product between a polyalkenylsuccinic anhydride and a polyalkylene glycol, and by treating the resulting product with boric acid, etc.
