Abstract
(EN)
Provided is a process whereby an aqueous dispersion of oxidized carbon black particles which is excellent in terms of dispersibility and storage stability is easily produced in the case where the aqueous dispersion of oxidized carbon black particles is produced by oxidizing carbon black particles in a liquid phase using a persulfuric acid salt. The process is for producing an aqueous dispersion of oxidized carbon black particles by contacting at least one persulfuric acid salt with carbon black particles to oxidize the carbon black particles in a liquid phase, and is characterized in that the persulfuric acid salt and the carbon black particles are contacted with each other in water in the presence of an inorganic alkali in an amount which is not smaller than a theoretical amount necessary for neutralizing an acidic reaction product to be generated by the liquid-phase oxidation, and that the liquid-phase oxidation is conducted with heating.

L'invention concerne un procédé grâce auquel une dispersion aqueuse de particules de noir de carbone oxydé qui est excellente en termes de dispersibilité et de stabilité au stockage est facilement produite dans le cas où la dispersion aqueuse de particules de noir de carbone oxydé est produite par oxydation de particules de noir de carbone dans une phase liquide à l'aide d'un sel d'acide persulfurique. Le procédé est destiné à la production d'une dispersion aqueuse de particules de noir de carbone oxydé par la mise en contact d'au moins un sel d'acide persulfurique avec des particules de noir de carbone pour oxyder les particules de noir de carbone dans une phase liquide, et est caractérisé en ce que le sel d'acide persulfurique et les particules de noir de carbone sont mis en contact les uns avec les autres dans de l'eau en présence d'un alcali inorganique dans une quantité qui n'est pas inférieure à une quantité théorique nécessaire pour neutraliser un produit de réaction acide généré par l'oxydation en phase liquide, et en ce que l'oxydation en phase liquide est effectuée sous chauffage.
