Zusatz zum Patente 235047 vom 15. Oktober 1908.Addendum to patent 235047 from October 15, 1908.
Patentiert im Deutschen Reiche vom 23. März 1909 ab. Längste Dauer: W.Oktober 1923.Patented in the German Empire on March 23, 1909. Longest duration: October 1923.
Nach dem Verfahren des Patentes 235047 erhält man haltbare, für dauernde Küpenführung geeignete Präparate aus Indigoleukofarbstoffen, wenn man diese mit Melasse, Sirup, Glycerin oder anderen nicht eintrocknenden Substanzen und anorganischen Reduktionsmitteln mischt.According to the method of patent 235047 one obtains durable, for permanent vat guidance suitable preparations from indigoleuco dyes, if these are mixed with molasses, syrup, Glycerine or other non-drying substances and inorganic reducing agents mixes.
Es wurde nun gefunden, daß diese Präparate auch unter Zusatz von Alkali oder alkalisch wirkenden Substanzen hergestellt werden können, ohne daß die Haltbarkeit beeinträchtigt wird. Der alkalische Zusatz verleiht den Präparaten eine geschmeidige, sirupöse Konsistenz, wodurch deren Verwendung in der Färberei erleichtert wird. Wie sich überraschenderweise gezeigt hat, genügen hierfür häufig schon ganz geringe Mengen von Alkalien, welche bei weitem nicht zur Überführung der Indigoleukofarbstoffe in die Salze ausreichen.It has now been found that these preparations can also be made with the addition of alkali or alkaline active substances can be produced without affecting the shelf life will. The alkaline addition gives the preparations a smooth, syrupy consistency, which facilitates their use in dyeing. How surprisingly has shown that very small amounts of alkalis are often sufficient for this purpose, and these are by no means for the conversion of the indigoleuco dyes in the salts are sufficient.
Man knetet 714 kg 70 prozentigen Indigweißpreßkuchen mit 210 kg Glycerin und kg Pottaschelösung (50 prozentig) oder Natronlauge (40 °) an und setzt alsdann allmählich 56 kg Zinkstaub zu. Das homogene Gemenge stellt eine Paste von sirupähnlicher Konsistenz dar.714 kg of 70 percent indigo white press cake are kneaded with 210 kg glycerine and kg potash solution (50 percent) or caustic soda (40 °) and then gradually adds 56 kg of zinc dust. The homogeneous mixture represents a paste of syrup-like Consistency.
