In der Patentschrift 147162 ist ein Verfahren zur Darstellung von trockenem, bei Berührung mit Wasser in feinen Teig zerfallendem Indigo in Stücken beschrieben, welches darin besteht, daß man Indigopaste mit Stärke, eventuell unter gleichzeitigem Zusatz von indifferenten Füllmitteln, wie Kieselguhr, Tripolith, Magnesia, Ton, Kreide, Speckstein oder dergl., mischt, filtriert, preßt undIn patent specification 147162 there is a method for the representation of dry dough that disintegrates in contact with water Indigo described in pieces, which consists in making indigo paste with starch, possibly with the addition of it at the same time of indifferent fillers such as kieselguhr, tripolite, magnesia, clay, chalk, soapstone Or the like. Mixes, filters, presses and

Es hat sich nun gezeigt, daß es bei der Verwendung von Laminariapulver an Stelle von Stärke (vergl. Patentschrift 149460) nicht erforderlich ist, von einer Indigopaste auszugehen, sondern daß man in diesem Falle das gleiche Resultat erreicht, wenn man ein Gemisch von feinem Indigopulver mit Laminariapulver trocken preßt. Man gelangt auf diese Weise ebenfalls zu Indigo in Stücken, welcher ohne vorherige Mahlung bei der Berührung mit Wasser sehr rasch in feine Teigform zerfällt, so daß er direkt zum Färben in der Küpe Verwendung finden kann. Die übrigen, in der Hauptpatentschrift genannten Substanzen können ebenfalls als Verdünnungsmittel gleichzeitig mit LaminariaIt has now been shown that when using laminaria powder in place of starch (see patent specification 149460) is not required, of an indigo paste but that in this case the same result can be achieved if one Mixture of fine indigo powder with laminaria powder. One arrives at this way also to indigo in pieces, which without prior grinding to the touch very quickly disintegrates into a fine dough shape with water, so that it can be used directly Dyeing can be used in the vat. The others mentioned in the main patent specification Substances can also be used as diluents at the same time as Laminaria

Reiner Indigo, welcher in trockenem Zustande einer starken Pressung ausgesetzt wurde, besitzt zwar schon die Eigenschaft, sich leicht mit Wasser zu benetzen und zu zerfallen, doch wird diese Fähigkeit durch den oben beschriebenen Zusatz von Laminariapulver wesentlich erhöht, so daß erst hierdurch der Zweck des Verfahrens des Hauptpatents, die Gewinnung eines ohne Naßmahlung für die Küpe direkt verwendbaren Produkts, erreicht wird.Pure indigo, which is exposed to strong pressure when dry has the property of being easily wetted with water and closed disintegrate, but this ability is enhanced by the addition of laminaria powder described above significantly increased, so that only hereby the purpose of the process of the main patent, the recovery of a product which can be used directly for the vat without wet grinding is achieved.
Das Verfahren wird durch folgende Beispiele erläutert:The procedure is illustrated by the following examples:
95 kg Indigo in Pulver werden mit 5 kg Laminariapulver gemischt und in Stücke gepreßt. 95 kg of indigo in powder are mixed with 5 kg of laminaria powder and pressed into pieces.
90 kg Indigo in Pulver werden mit 5 kg Stärke und 5 kg Laminariapulver vermischt und gepreßt. -90 kg of indigo in powder are mixed with 5 kg of starch and 5 kg of laminaria powder and pressed. -
