摘要:
A reaction product useful as an antiwear or antioxidant additive in lubricants is made by reacting a sulfur-containing carboxylic acid, i.e. 3,3'-thiodipropionic acid and a phosphorodithioate, i.e. butoxylated bis(2-ethylhexyl) phosphorodithioic acid.
摘要:
A lubricant additive having antiwear and antioxidant properties is the reaction product of a sulfur-containing carboxylic acid and an etheramine, preferably 3,3'-thiodipropionic acid and N-isoeicosyloxypropyl-1,3-diaminopropane which is post reacted with an aliphatic alcohol, preferably oleyl alcohol, an aliphatic amine, preferably a tert-C.sub.12 to C.sub.14 amine and/or a trialkyl phosphite, preferably a tributylphosphite. The post-reaction product contains at least one ester, amide and/or phosphonate functional group.
