PURPOSE:The titled additive excellent in lubricity between solid faces and corrosion resistance, and giving ability to coat the surface of matter with a hydrophilic group, which comprises a specified org. titanium compd. CONSTITUTION:Titanium alkoxide is reacted with an 8-24C fatty acid to obtain an additive for lube oil comprising an org. titanium compd. of the formula I {wherein COOR is an 8-24C fatty acid residue; A is at least one group selected from among hydrolyzable groups of the formulas R<1>O, II and III [wherein R<1> is (non)substd. 1-24C alkyl; R<2-3> is -CH2- or a group of the formula IV; Y is CH3- or R<4>O- (wherein R<4> is 1-4C alkyl)]; n=1-3 provided that n+m=4}. Then 0.01-5pts.wt. said additive is added to 100pts.wt. lube oil. |
