Abstract
Dithiocarbamyl carboxylic acids, useful as multifunctional additives for lubricating oils, possess the general formula: ##STR1## wherein R.sup.1 and R.sup.2 each independently is a hydrocarbyl group of from 1 to about 60 carbon atoms and R.sup.3 is a divalent alkylene group of from 1 to about 20 carbon atoms.
Claims14
A lubricating oil composition comprising a lubricating oil and a functional property-improving amount of at least one dithiocarbamyl carboxylic acid of the general formula ##STR4## wherein R.sup.1 and R.sup.2 each independently is a hydrocarbyl group of from 1 to about 60 carbon atoms and R.sup.3 is a divalent alkylene group of from 1 to about 20 carbon atoms.
A method for improving at least one functional property of a lubricating oil which comprises adding to the lubricating oil a functional property-improving amount of at least one dithiocarbamyl carboxylic acid of the general formula ##STR5## wherein R.sup.1 and R.sup.2 each independently is a hydrocarbyl group of from 1 to about 60 carbon atoms and R.sup.3 is a divalent alkylene group of from 1 to about 20 carbon atoms.
