SULFUR-CONTAINING ORGANOPHOSPHORUS COMPOUNDS |
摘要 |
New sulfur-containing organophosphorus compounds of general formulae (I) and (II) and processes for producing the same; additives for lubricating oils, which contain the sulfur-containing organophosphorus compounds; and lubricating oil compositions satisfying requirements of extreme-pressure lubrication and abrasion resistance under severe conditions of high loads imposed, on automatic or continuously variable transmissions or the like. In said formulae, R1 is a hydrocarbon group having 6 to 20 carbon atoms; R2 is a divalent hydrocarbon group having 1 to 6 carbon atoms; n is an integer of 1 to 3; p is an integer of 0 to 2; and q is an integer of 0 or 1, with the proviso that p and q cannot be 0 at the same time.
