Anstatt die Naphtolsulfosäuren zu trennen und Azofarbstoffe aus den reinen Naphtolsulfosäuren darzustellen, kann man gewisse Azoverbindungen durch die verschiedene Löslichkeit ihrer Thonerde-, Kalk-, Baryt- und Strontiansalze von einander scheiden.Instead of separating the naphthol sulfonic acids and azo dyes from the pure naphthol sulfonic acids one can represent certain azo compounds by the different solubility their alumina, lime, barite and strontian salts separate from each other.
Diese Trennung läfst sich besonders gut anwenden bei Azofarbstoffen, welche dargestellt sind aus einem Gemenge der Alpha- und Betamonosulfosäure des Betanaphtols mit Diazonaphtalinmonosulfosäure und Diazoazobenzolmonosulfosäure (Anspruch L), sowie aus einem Gemenge der Di- und Trisulfosäure des Betanaphtols mit Diazonaphtalinmonosulfosäure, Diazoazobenzol und Diazoazobenzolmonosulfosäure (Anspruch IL).This separation can be used particularly well in the case of azo dyes, which are shown are made from a mixture of alpha and beta monosulphonic acid of betanaphthol with diazonaphthalene monosulphonic acid and diazoazobenzene monosulfonic acid (claim L), as well as from a mixture of the di- and trisulfonic acid of betanaphthol with diazonaphthalene monosulfonic acid, diazoazobenzene and diazoazobenzenesulfonic acid (claim IL).
Beispiel zu Anspruch I.Example for claim I.
50 kg Farbstoff, dargestellt aus Alphadiazonaphtalinmonosulfosäure und den gemischten Alpha- und Betamonosulfosäuren des Betanaphtols, werden in ca. 1000 1 Wasser heifs gelöst; es wird so lange eine Lösung von schwefelsaurer Thonerde und Ammoniak zugegeben, als noch ein Niederschlag beim Erkalten erfolgt. Man läfst nun erkalten und filtrirt von dem Thonerdelack des Farbstoffes der Betasulfosäure des Betanaphtols ab. Im Filtrat fällt man den Farbstoff der Alphasulfosäure des Betanaphtols mit Kochsalz aus.50 kg of dye, prepared from alphadiazonaphthalene monosulfonic acid and the mixed alpha and betamonosulphonic acids of betanaphthol become hot in approx. 1000 liters of water solved; a solution of sulfuric alumina and ammonia is added so long when there is still a precipitate on cooling. It is now allowed to cool and filtered off the alumina varnish of the dye of the beta sulfonic acid of betanaphthol. Falls in the filtrate the pigment of the alpha sulfonic acid of betanaphthol with table salt.
Beispiel zu Anspruch II.Example for claim II.
50 kg Farbstoff, dargestellt aus den ge^ mischten Di- und Trisulfosäuren des Beta-' naphtols (durch Einwirkung von rauchender Schwefelsäure auf Betanaphtol bei 130 bis 1400C.) und Diazoazobenzolmonosulfosäure, werden in ca. 1000 1 Wasser heifs gelöst und so lange mit einer Lösung von schwefelsaurer Thonerde und Ammoniak versetzt, als noch ein Niederschlag beim Erkalten erfolgt. Man läfst erkalten und filtrirt von dem Thonerdelack des Farbstoffes der Betanaphtoldisulfosäure ab. Im Filtrat fällt man den Farbstoff der Betanaphtoltrisulfosäure mit Kochsalz aus.50 kg dye represented from the ge ^ mixed di- and Trisulfosäuren of beta 'naphthol (by exposure to fuming sulfuric acid to Betanaphtol at 130 to 140 0 C.) and Diazoazobenzolmonosulfosäure, are dissolved in 1000 1 of water remains hot, and so long mixed with a solution of sulfuric alumina and ammonia when a precipitate still occurs on cooling. It is allowed to cool and the alumina varnish of the dye of betanaphthol disulphonic acid is filtered off. The dye of betanaphtholtrisulfonic acid is precipitated in the filtrate with common salt.
An Stelle der Thonerdesalze können auch die Kalk-, Baryt- und Strontiansalze angewendet werden.The lime, barite and strontian salts can also be used in place of the clay salts will.
Wendet man z. B. zur Trennung des Farbstoffes (Anspruch L), der aus gemischter Alpha- und Betamonosulfosäure des Betanaphtols und Alphadiazonaphtalinmonosulfosäure gewonnen ist, anstatt Thonerde einen Ueberschufs von Chlorcalcium an, so scheidet sich das Kalksalz des F'arbstoffes der Alphasulfosäure des Betanaphtols beim Erkalten in Krystallen aus.If you apply z. B. to separate the dye (claim L), which consists of mixed alpha and betamonosulfonic acid of betanaphthol and alphadiazonaphthalene monosulfonic acid is obtained, instead of alumina with an excess of calcium chloride, the calcium salt separates out The dye of the alpha sulfonic acid of betanaphthol is removed in crystals when it cools.
