PATENTAMTPATENT OFFICE
Zu den alkalischen Reductionsmitteln, welche, ähnlich wie Trauben- oder Milchzucker, die Umwandlung der Orthonitrophenylpropiolsäure bewirken, gehören nach ferneren Erfahrungen die Sulfide, SuIf hydrate, Polysulfide, sulfocarbonsauren und äthersulfocarbonsauren Salze der Alkalien und alkalischen Erden und insbesondere die alkalischen Xanthogenate.The alkaline reducing agents, which, similar to grape or lactose, the Conversion of the orthonitrophenylpropiolic acid belong to further experiences the sulfides, sulfhydrates, polysulfides, sulfocarboxylic acids and ether sulfocarboxylic acid salts of alkalis and alkaline earths and in particular the alkaline xanthates.
Genannte Reductionsmittel wirken bereits in der Kälte und schneller beim Erwärmen in wässriger oder alkoholischer Lösung. Bei Anwendung der Xanthogenate tritt die Bildung des künstlichen Indigos vornehmlich nach dem Verdunsten des Lösungsmittels ein.These reducing agents already work in the cold and faster when heated in aqueous or alcoholic solution. When the xanthates are used, the formation occurs of the artificial indigo mainly after the solvent has evaporated.
So bewirkt z. B. der Zusatz eines alkalischen Sulfhydrats zu der Lösung eines alkalischen Salzes der Orthonitrophenylpropiolsäure nach kurzer Zeit in der Kälte und sofort beim Erwärmen die Abscheidung eines Niederschlages, der aufser Indigoblau und freiem Schwefel auch noch violette und rothe, in Alkohol lösliche Farbstoffe der Indigogruppe enthält.So z. B. the addition of an alkaline sulfhydrate to the solution of an alkaline The salt of orthonitrophenylpropiolic acid after a short time in the cold and immediately when heated the deposition of a precipitate, apart from indigo blue and free sulfur, too still contains violet and red, alcohol-soluble dyes of the indigo group.
Noch energischer ist der Reactionsverlauf bei der Anwendung eines alkalischen Polysulfids, das in concentrirter Lösung und bis zum bleibenden Ueberschufs, zur concentrirten Lösung eines alkalischen Orthonitrophenylpropiolates gesetzt, sofort die reichliche Abscheidung von künstlichem Indigo bewirkt.The course of the reaction is even more energetic when an alkaline polysulphide is used, that in concentrated solution and up to the permanent excess, to concentrated solution of an alkaline orthonitrophenylpropiolate, immediately the copious deposition of artificial indigo.
Bei Anwendung xanthogensaurer Salze verfahren wir folgendermafsen:When using xanthic acid salts, we proceed as follows:
ι kg Orthonitrophenylpropiolsäure wird in etwa der halben Gewichtsmenge kalten Wassers vertheilt, darauf 0,5 kg kohlensaures Kali zugesetzt und nach erfolgter Neutralisation mit 1,5 kg xanthogensaurem Kali sorgfältig gemischt. Die entstandene Mischung läfst man bei gewöhnlicher Temperatur eintrocknen. Die Farbstoffbildung schreitet schnell vorwärts und ist beendigt, wenn unveränderte Orthonitrophenylpropiolsäure sich nicht mehr nachweisen läfst. Das dunkelblaue Product wird dann mit Wasser gewaschen, filtrirt und getrocknet und kann durch Anwendung geeigneter Lösungsmittel, wie Schwefelkohlenstoff oder Alkohol, weiter gereinigt werden.ι kg of orthonitrophenylpropiolic acid is used in about half the weight of cold water is distributed, then 0.5 kg of carbonate of potash is added and after neutralization, carefully mixed with 1.5 kg of xanthogenic potash. The resulting mixture is left to dry out at normal temperature. The dye formation advances rapidly and is quit when orthonitrophenylpropiolic acid is unchanged can no longer be proven. The dark blue product is then washed with water, filtered and dried, and can by using suitable solvents such as carbon disulfide or alcohol getting cleaned.
Die vorerwähnten Ersatzmittel des Trauben- oder Milchzuckers und vorzugsweise die xanthogensauren Salze gestatten ebenfalls, den künstlichen Indigo direct auf der Faser zu erzeugen.The aforementioned substitutes for grape or milk sugar and preferably the xanthogenic acids Salts also make it possible to produce the artificial indigo directly on the fiber.
Wir nehmen z. B. das wie vorstehend bereitete Gemisch von orthonitrophenylpropiolsaurem Kali und xanthogensaurem Kali, verdünnen dasselbe mit so viel Wasser oder Verdickungsmittel, als dem zu erzielenden Farbenton entspricht, und imprägniren, zeichnen oder bedrucken die Faser mit demselben. Die Mischung mufs baldmöglichst verwendet werden, da sie sich beim längeren Aufbewahren zersetzt. Wir können auch die Faser zuerst mit einem der genannten Salze präpariren und dann mit dem anderen Salz imprägniren, zeichnen oderWe take e.g. B. the mixture of orthonitrophenylpropiolsaurem prepared as above Potash and xanthogenic potash, dilute the same with as much water or thickener as that to be obtained Color tone, and impregnate, draw or print the fiber with the same. the Mixture must be used as soon as possible as it will degrade if stored for a long time. We can also prepare the fiber first with one of the salts mentioned and then with impregnate with the other salt, draw or
bedrucken. In allen Fällen tritt die Farbstoffbildung nach dem Trocknen bereits in der Kälte und schneller in einem Trockenraume ein.to print. In all cases, dye formation occurs after drying already in the Cold and faster in a drying room.
