Neue Farbstoffe, welche Baumwolle direct anfärben, erhält man, wenn man auf die Nitro-, Amido- und Sulfoderivate des Nitro-m-kresols (OH: CH3: NO2- 1:3:6; Schwefel und Schwefelalkalien oder dem Schwefel' und Schwefelalkali ähnlich wirkende Producte bei höherer Temperatur einwirken läfst.New dyes that directly dye cotton are obtained by using the nitro, amido and sulfo derivatives of nitro-m-cresol (OH: CH 3 : NO 2 - 1: 3: 6; sulfur and alkaline sulfur or sulfur ' and allows alkali-sulfur products to act at a higher temperature.
Beispiel 1.Example 1.
20 kg Trinitro-m-kresol werden, nachdem eine Lösung von 100 kg krystallisirtem Schwefelnatrium in ca. 50 1 Wasser auf ioo° angewärmt ist, allmählich in kleinen Portionen eingetragen. Wenn die sehr lebhafte Reaction vorüber ist und die Schmelze zähflüssiger zu werden beginnt, giebt man 20 kg Schwefel hinzu und steigert alsdann unter gutem Umrühren die Temperatur zunächst auf i6o° und dann über 2000.20 kg of trinitro-m-cresol are gradually added in small portions after a solution of 100 kg of crystallized sodium sulphide in about 50 liters of water has been warmed to 100 °. If the very lively reaction is over and the melt starts to become more viscous, it gives Add 20 kg of sulfur and the temperature initially increases then stirring well to I6O ° and then 200 0th
Die Masse kann direct zum Färben verwendet werden und liefert auf Baumwolle graubraune bis olive Färbungen, welche durch Nachbehandeln mit Chromkali oder Kupfervitriol wenig verändert werden.The mass can be used directly for dyeing and delivers on cotton gray-brown to olive colorations, which are caused by post-treatment with chromium potassium or copper vitriol to be changed little.
63 kg Aetznatron und 45 kg Schwefel werden in ungefähr 60 1 heifsem Wasser gelöst und in die auf 1200 erhitzte Lösung allmählich unter stetigem Umrühren 42 kg mononitro-m-kresolsulfosaures Kali eingetragen. Nach Beendigung der wenig lebhaften Reaction wird die Temperatur zunächst bis zum Festwerden der Schmelzmasse auf i6o° gesteigert und endlich noch mehrere Stunden auf 2300 erhitzt. Die Masse kann dann direct zum Färben von Baumwolle verwendet werden, welche sie tief braun anfärbt.63 kg of caustic soda and 45 kg of sulfur is dissolved in about 60 1 hot water, and gradually added to the heated solution to 120 0 with constant stirring, 42 kg mono nitro-m-kresolsulfosaures potash. After completion of the bit lively reaction, the temperature is first increased to the solidification of the melt on I6O ° and finally heated for several hours to 230 0th The mass can then be used directly for dyeing cotton, which dyes it deep brown.
Ganz ähnliche Nuancen erhält man bei Anwendung von Dinitroamido-m-kresol und von Dinitro-m-kresolsulfosäure.Very similar nuances are obtained when applied of dinitroamido-m-cresol and of dinitro-m-cresolsulfonic acid.

Mono- und Dinitrokresolsulfosäure sind aus siilfonirtem m-Kresol durch mehr oder weniger starkes Nitriren herstellbar. Die Alkalisalze bilden gelbe Krystallmassen und lassen sich aus heifsem Wasser umkrystallisiren.Mono- and dinitro-cresol sulfonic acid are more or less made of siliconized m-cresol strong nitriding can be produced. The alkali salts form yellow crystalline masses and can be recrystallize from hot water.
