Abstract

Procédé du genre de ceux utilisés pour le traitement ultérieur du tétrachloro-4,4', 7,7' thioindigo qui a été obtenu par les procédés connus. Le produit brut est malaxé avec de l'acide sulfurique, la viscosité étant telle qu'il apparaise encore des efforts de cisaillement, avec éventuellement un auxiliaire de broyage et/ou un hydrocarbure. Le procédé s'applique en particulier aux produits bruts qui contiennent du bioxyde de manganèse.A process of the kind used for the subsequent treatment of 4,4 ', 7,7' tetrachloro-thioindigo which has been obtained by known processes. The crude product is kneaded with sulfuric acid, the viscosity being such that shearing forces still appear, optionally with a grinding aid and / or a hydrocarbon. The process applies in particular to crude products which contain manganese dioxide.
