Abstract
A borated oxazoline monoester, made by reacting a boron compound with the product of reaction between tris(hydroxymethyl)aminomethane and carboxylic acid is a new composition of matter. It is useful in a lubricating oil for reducing friction, and, therefore, fuel consumption in an internal combustion engine.
Claims12
A compound of the formula:
- ##STR4## wherein R is the same or different hydrocarbyl having 9 to 49 carbon atoms, m is 1 to 3, n is 0 to 2 and M is H or R', R' being an alkyl containing 1 to 6 carbon atoms.
A lubricant composition comprising a major proportion of a lubricant and a friction reducing amount of a compound of the formula:
- ##STR5## wherein R is the same or different hydrocarbyl having 9 to 49 carbon atoms, m is 1 to 3, n is 0 to 2 and M is H or R', R' being an alkyl containing 1 to 6 carbon atoms.
A method of reducing fuel consumption in an internal combustion engine comprising lubricating said engine with a lubricant composition comprising a lubricating oil and a fuel consumption reducing amount of a compound of the formula ##STR6## wherein R is the same or different hydrocarbyl having 9 to 49 carbon atoms, m is 1 to 3, n is 0 to 2 and M is H or R', R' being an alkyl containing 1 to 6 carbon atoms.
