KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. PATENTSCHRIFTPATENT LETTERING KLASSE 22: Farbstoffe, Firnisse, Lacke.CLASS 22: dyes, varnishes, lacquers. Patentirt im Deutschen Reiche vom 22. September 1886 ab.Patented in the German Empire on September 22, 1886. Erhitzt man die in der Patentschrift Nr. 42 1 1 2 beschriebene neue Naphtolmonosultosäure F mit Ammoniak, so tauscht sich die O //-Gruppe gegen NII,, aus und man erhält eine neue Naphtylaminsulfosäure, welche als Naphtylaminsulfosäure F bezeichnet werden soll.If the new naphthol monosulphonic acid F described in patent specification No. 42 1 1 2 is heated with ammonia, the O // group is exchanged for NII ,, and a new naphthylamine sulphonic acid, which is to be referred to as naphthylamine sulphonic acid F, is obtained. Zur Darstellung derselben wird zweckmäfsig in folgender Weise verfahren:To represent the same, the following procedure is expedient: Man kann entweder z. B. 30 kg F-naphtolsullosaures Natron mit ΐόο kg Ammoniak (20 pCt.) 6 Stunden auf 250° im Autoclaven erhitzen oder, unmittelbar von der a-Naphtalindisulfosäure ausgehend, dieselbe mit NaOH und JVi/, erhitzen.You can either z. B. Heat 30 kg of F-naphthol sulphonic acid with ΐόο kg of ammonia (20 pCt.) 6 hours at 250 ° in the autoclave or, starting directly from the a-naphthalene disulphonic acid, heat the same with NaOH and JVi /. Z. B. 'Vi kg O- - naphtalindisulfosaures Natron werden in einem Autoclaven mit 25 kg Natronlauge von 40 pCt. 10 Stunden auf 200 bis 2io° erhitzt und hierauf 7 kg Chlorammonium oder die äquivalente Menge eines anderen Ammoniaksalzes in 20 1 Wasser gelöst, zugesetzt und die Temperatur weiter 10 Stunden lang auf 200 bis 2500 gehalten.Eg 'Vi kg O- - naphtalindisulfosaures soda are cent in an autoclave with 25 kg of sodium hydroxide solution from 40th Heated for 10 hours at 200 ° to 2io and then dissolved 7 kg of ammonium chloride or the equivalent amount of another salt of ammonia in 20 1 water was added and the temperature was kept further for 10 hours at 200 to 250 0th In beiden Fallen scheidet sich beim Ansäuern der in kochendem Wasser gelösten Reactionsmasse die F-Naphtylaminsulfosäure als weifser krystallinischer Niederschlag aus; derselbe wird nach dem Erkalten abfiltrirt und durch Auswaschen mit Wasser völlig rein erhalten. In both cases, when acidified, the dissolved in boiling water separates Reaction mass the F-naphthylamine sulfonic acid as a white crystalline precipitate; it is filtered off after cooling and is kept completely pure by washing with water. Die Lösungen der Salze der F-Säure fluoresciren rothviolett. Das Natriumsalz ist ziemlich schwer löslich und krystallisirt in Nadeln. Beim Behandeln mit salpetriger Säure löst sich die Säure mit gelblicher Farbe zu der in Wasser sehr leicht löslichen Diazoverbindung. Diese vereinigt sich mit Aminen und Phenolen zu einer Reihe von Farbstoffen, die durch dunkle Töne sich von den analogen, bis jetzt bekannten unterscheiden.The solutions of the salts of the F-acid fluoresce red-violet. The sodium salt is pretty poorly soluble and crystallizes in needles. When treated with nitrous acid dissolves the yellowish acid to the diazo compound, which is very easily soluble in water. This combines with amines and phenols to form a series of dyes, which through dark tones differ from the analog ones known up to now. Die Farbstoffe, welche man durch Einwirkung von Diazoverbindungen auf die F-Säure erhält, zeichnen sich durch Beständigkeit und Klarheit der Nuancen aus.The dyes obtained by the action of diazo compounds on the F-acid are characterized by persistence and clarity of nuances.
