l'ATENT. ANSPRUCH : Weitere Ausbildung des durch das Stammpatcnt Nr. 38353 und dessen Zusatzpatent Nr. 38490 geschützten Verfahrens zur Darstellung von schwefelhaltigen Küpenfarbstoffen der Anthrazenreihe, darin bestehend, dass man zwecks Gewinnung von orange färbenden EMI2.1 anthrachinon mit Schwefel bei unter 3000 liegenden Temperaturen erhältlichen Rohfarbstoffe vor der Hypochloritbehandlung der Einwirkung von konzentrierter Schwefelsäure unterworfen werden. latent. CLAIM : Further development of the process for the preparation of sulfur-containing vat dyes of the anthracene series, which is protected by the parent patent no. 38353 and its additional patent no. 38490, consists in the fact that for the purpose of obtaining orange coloring EMI2.1 anthraquinone with sulfur at temperatures below 3000 available raw dyes are subjected to the action of concentrated sulfuric acid before the hypochlorite treatment.
