  Bleichverfahren. 
 EMI1.1 
 nämlich bei   Gegenwart einer zu reichenden Substanz Sauerstoff   resp. Luft durch eine alkalisch reagierende verdünnte wässrige Lösung, z.   B.   von   Alkalihydroxyd, Erdallkaii-     hydroxyd oder einem Alkali- oder Erdkalisalz (Karbonat, Borat, Silikat usw. ) am besten   bei erhöhter Temperatur unter Druck, so tritt eine Bindung des Sauerstoffes und Widergabe an   das Bleichgut   ein. Auf diese Weise kann män z. B. Baumwolle, die in einer   l%igen auf 2 Atm.   Dampfdruck erhitzten   Ätznatronlösung   suspendiert ist, durch hinein- 
 EMI1.2 
 verstärken, wenn man in der alkalischen Lösung kleine Mengen eines   anderen Metallsalzcs   oder   Metalloxyds auflöst   oder suspendiert.

   Bringt man z. B. die gleiche Baumwolle, wie 
 EMI1.3 
   gesetzt   sind, erhitzt,   auf H Atm.   und presst   Luft in die Ftüssigkcit,   so ist schon nach 12StundenderBleichprozessbeendet.

  Bleaching process.

 namely in the presence of a substance to be reached oxygen respectively. Air through an alkaline reacting dilute aqueous solution, e.g. B. of alkali hydroxide, Erdallkaii- hydroxyd or an alkali or alkaline earth salt (carbonate, borate, silicate, etc.) is best at elevated temperature under pressure, so a bond of the oxygen and reproduction occurs on the bleached material. In this way, man z. B. Cotton, which is in a 1% strength to 2 atm. Steam pressure heated caustic soda solution is suspended by in-

 increase if small amounts of another metal salt or metal oxide are dissolved or suspended in the alkaline solution.

   If you bring z. B. the same cotton as

   are set, heated, to H Atm. and presses air into the liquid, the bleaching process is over after just 12 hours.
