Pate nt-An s PRU ch:Pate nt-An s PRU ch:Verfahren zur Herstellung von Sulfosäuren aromatischer Aminoazoverbindungen,
welche den Rest eines primären aromatischen Monamins der Benzolreihe enthalten, darin bestehend, daß man die Diazoverbindungen
aromatischer Sulfosäuren auf Arylsulfanilide einwirken läßt und aus
dem so erhaltenen Arylsulfaminoazokörper den Arylsulforest abspaltet.Process for the preparation of sulfonic acids of aromatic aminoazo compounds,
which contain the remainder of a primary aromatic monamine of the benzene series, consisting in that one the diazo compounds
aromatic sulfonic acids can act on aryl sulfanilides and off
the aryl sulfaminoazo body obtained in this way cleaves the aryl sulfo radical.
