Abstract (en)
[origin: EP1602709A1] Additives for lubricating oils and for fuel oils which comprise as the main component a disulfide represented by the following general formula (I) or (IV): R<1>OOC-A<1>-Sx-A<2>-COOR<2> (R<1> and R<2> each independently represent a hydrocarbyl group which has 1 to 30 carbon atoms and may have oxygen atom, sulfur atom or nitrogen atom, A<1> and A<2> each independently represent a group represented by CR<3>R<4>, R<3> and R<4> each independently representing hydrogen atom or a hydrocarbyl group having 1 to 20 carbon atoms, and x represents 2.) R<1>OOC-A<3>-Sx-A<4>-COOR<2> (R<1> and R<2> are as defined above, A<3> and A<4> each independently represent a group represented by CR<5>R<6>-CR<7>R<8>, R<5> to R<8> each independently representing hydrogen atom or a hydrocarbyl group having 1 to 20 carbon atoms, and x represents 2.) The additives exhibit excellent functions as the extreme pressure additive and the antiwear agent and the suppressed corrosive property to nonferrous metals and are advantageously used as the sulfur-based extreme pressure additives for lubricating oils and fuel oils.
