ABSTRACT:
A novel hydroxyalkyldithiocarbamate borate ester compound is presented according to the formula:where R=alkyl C1to C25; R′=H or CO2R; R″=(CH2)mOH where m=1 to 8, or alkyl C1to C25; 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 CS2, 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.
