Abstract
A novel hydroxyalkyldithiocarbamate borate ester compound is presented according to the formula: where R=alkyl Cto C; R'=H or COR; R″=(CH)OH where m=1 to 8, or alkyl Cto C; n=1 to 8. The borate ester compound is prepared by reacting boric acid with a novel hydroxyalkyldithiocarbamate ester compound according to the formula, and optionally with an alcohol: where R, R′, R″ and n are as above. The hydroxyalkyldithiocarbamate ester is prepared by reacting a hydroxyalkylamine with CS, and an acrylate or maleate compound. A lubricating composition is based on a major amount of lubricating oil and a minor amount of the hydroxyalkyldithiocarbamate borate ester.
