Abstract
Boron and/or metal-boron derivatives having extreme pressure anti-wear and friction reducing properties and lubricating compositions containing the same are disclosed. The lubricating compositions comprise a major amount of a lubricating oil and a minor amount of an extreme pressure, anti-wear and friction reducing additive comprising a boramid or metal containing boramid compound.
Claims16
An extreme pressure, anti-wear lubricating composition comprising a major amount of a lubricating oil and a minor amount of an extreme pressure, anti-wear additive of the formula:
- ##STR3## wherein R is hydrogen, alkyl, cyclic, alicyclic, aryl, alkylaryl or arylalkyl radical having from about 1 to about 24 carbon atoms, R' and R" are either straight or branched carbon chain, cyclic or alicyclic radicals having from 2 to about 20 carbon atoms, y is an integer of 1 to 4, and X is either hydrogen or a metal selected from a transition metal having an atomic number between 21 and 30 or a Group IVA metal and mixtures thereof.
An extreme pressure, anti-wear lubricating composition comprising a major amount of a lubricating oil and a minor amount of an extreme pressure, anti-wear additive selected from, ethylaminodiethylate hydrogen borate, propylaminodiethylate hydrogen borate, butylaminodiethylate hydrogen borate, octadecylaminodiethylate hydrogen borate, dodecylaminodiethylate hydrogen borate, cyclohexylaminodiethylate hydrogen borate, phenylaminodiethylate hydrogen borate, oleylaminodiethylate hydrogen borate, cocoaminodiethylate hydrogen borate, or tallowaminodiethylate hydrogen borate and mixtures thereof.
An extreme pressure, anti-wear lubricating composition comprising a lubricating oil and from about 0.1 to about 15 weight percent of an extreme pressure, anti-wear additive selected from methylaminodiethylate hydrogen borate, phenylaminodiethylate hydrogen borate, octadecylaminodiethylate hydrogen borate, cocoaminodiethylate hydrogen borate and tallowaminodiethylate hydrogen borate and mixtures thereof.
An extreme pressure, anti-wear lubricating composition comprising a major amount of a lubricating oil and a minor amount of an extreme pressure, anti-wear additive of the formula:
- ##STR4## wherein R is hydrogen, alkyl, cyclic, alicyclic, aryl, alkylary or arylalkyl radical having from about 1 to about 10 carbon atoms, R' and R" are either straight or branched carbon chains having from 2 to about 20 carbon atoms, y is an integer of 1 to 4, and X is either hydrogen or a metal selected from a transition metal having an atomic number between 21 and 30 or a Group IV metal and mixtures thereof.
An extreme pressure, anti-wear lubricating composition comprising a major amount of a lubricating oil and a minor amount of an extreme pressure, anti-wear additive of the formula:
- ##STR5## wherein R is hydrogen alkyl, cyclic, alicyclic, aryl, alkylaryl or arylalkyl radical having from about 1 to about 24 carbon atoms, R' and R" are straight or branched alkyl carbon chains having from 2 to about 10 carbon atoms, y is an integer of 1 to 4, and X is either hydrogen or a metal selected from a transition metal having an atomic number between 21 and 30 or a Group IV metal and mixtures thereof.
