摘要:
Tolyltriazole derived esters of tri, tetra, and poly carboxylic acids or an acid generating compound have been found to be effective lubricity additives for lube oils, greases, or distillate fuels.
摘要:
A lubricant of fuel composition contains a multifunctional antioxidant/metal deactivating and thermal stabilizing amount of a tolyltriazole-derived Mannich base made from a tolyltriazole, an aliphatic amine, such as diisobutylamine or bis(2-ethylhexyl)amine, a cyclic amine, such as 1,4-diaminocyclohexane or ether amines exemplified by C.sub.6 to C.sub.13 alkoxypropylamines and polyether primary amines such as those derived from nonylphenol ethyoxylates and formaldehyde. The reaction products are, optionally, treated with epoxide.
摘要:
A lubricant or fuel composition contains a multifunctional antioxidant and antiwear amount of an O,O-diorgano-S-(2-hydroxyalkyl) phosphorodithioate derived hydrogen phosphonate which can be made by reacting a diorganophosphorodithioic acid with an epoxide and a dialkyl phosphite, such as dimethyl phosphite.
