A process for producing a bismuth dithiocarbamate or dithiophosphorate by the reaction of a bismuth hydroxide, bismuth oxide or bismuth oxynitrate with a dithiocarbamate or a dithiophosphoric acid. The bismuth dithiocarbamates and dithiophosphorates exhibit very good EP and antiwear properties and are useful in lubricant formulations.
La présente invention concerne un procédé de production de dithiocarbamates et dithiophosphorates de bismuth par réaction d'un hydroxide de bismuth ou d'un oxynitrate de bismuth avec un dithiocarbamate ou un acide dithiophosphorique. Les dithiocarbamates et dithiophosphorates de bismuth, qui font preuve de très bonnes propriétés extrême-pression et anti-usure, conviennent particulièrement pour les formulations de lubrifiants.
