BENZOTRIAZOLE-SULFURIZED OLEFIN COMPOSITIONS AND LUBRICANTS AND CONCENTRATES CONTAINING THEM Abstract Compositions comprising (A) at least one benzo-triazole or reaction product thereof with an aliphatic amine and (B) a sulfurization product of at least one aliphatic or alicyclic olefinic compound are useful in lubricants, espe-cially gear lubricants, as additives capable of affording long-lasting extreme pressure properties and antiwear capability and having relative inertness to copper parts. Component A is preferably benzotriazole or tolyltriazole, and component B is preferably the reaction product of a sulfur-hydrogen sulfide mixture with propene, isobutene, or a dimer, trimer or tetramer thereof. |
