ABSTRACT:
The corrosion inhibited lubricants according to the present invention are comprised of fluorine-containing alkyl carbonyl, fluorine-containing alkylmethyl, ethylcarbonyl, polyperfluorooxyalkylenefluoropropionyl, polyperfluorooxyalkylene copolymerized with oxyfluoro-alkyl carbonyl chains and the like, and which compounds are reacted with hetero cyclic groups and obtained by amidization with polar groups between the radicals and compounds with typical organic end-groups.
The novel compounds referred to above are lubricants with anti-corrosive properties characterized in that they can be represented by the general formula (1) and that the molecular weight of Rf ranges from 200 to 15,000, preferably from 200 to 10,000.
