<p>The properties of salts of dialkylphosphorodithioic acids are improved by treating said salts or their acid precursors with phosphites, especially triaryl phosphites. This process reduces the tendency of the salts to stain and corrode metal parts, especially copper parts, when incorporated in lubricants and functional fluids. The process may also be used to treat mixed metal salts of dialkylphosphorodithioic and carboxylic acids.</p> |
