HYDROXYALKYLDITHIOCARBAMATE ESTERS AND BORATE ESTERS

摘要

A novel hydroxyalkyldithiocarbamate borate ester compound is presented according to the formula I: (I) where R=alkyl C₁ to C₂₅;_{R'=H or CO2 R; R"= (CH2)m,OH where m=1 to 8, or alkyl C1 to 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 [formula II: (II)] 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.}
