GROUP VI{14 B TRANSITION METAL-AMINO-PHOSPHORODITHIOATES IN LUBRICATING OIL

摘要

Group VI-B transition metal-amino-phosphorodithioates, which are the reaction products of amine salts of Group VI-B oxyacids and phosphorodithioic acids, are disclosed. A process for producing the beforementioned compounds is also disclosed that comprises contacting an acidic aqueous medium containing the Group VI-B metal source with a water-immiscible organic medium containing an alkyl amine and reacting said product with a phosphorodithioic acid and recovering the compounds of this invention. Lubricating compositions containing the compounds of this invention are also disclosed.
