Description

Verfahren zum Bleichen von Fettstoffen pflanzlicher oder tierischer Herkunft Gegenstand des Hauptpatents 5a6 419 ist ein Verfahren zum Bleichen von Fettstoffen pflanzlicher oder tierischer Herkunft mit Oxydationsmitteln und anschließender Behandlung mit Reduktionsmitteln, welches dadurch gekennzeichnet ist, daß als Reduktionsmittel der als Bleichmittel an sich bekannte, aus wäßrigen Säuren erzeugte, naszierende Wasserstoff verwendet wird. Unter der Behandlung mit Oxydationsmitteln werden dabei die bekannten oxydierenden Bleichverfahren verstanden, bei denen z. B. Chlorat und Säure oder Bichromat und Schwefelsäure u. dgl. als Oxydationsmittel angewendet werden.Process for bleaching fatty substances of vegetable or animal origin Origin The subject of the main patent 5a6 419 is a process for bleaching Fatty substances of vegetable or animal origin with oxidizing agents and then Treatment with reducing agents, which is characterized in that as a reducing agent the nascent one which is known per se as a bleaching agent and is produced from aqueous acids Hydrogen is used. Under the treatment with oxidizing agents are thereby understood the known oxidizing bleaching process in which z. B. Chlorate and Acid or bichromate and sulfuric acid and the like can be used as oxidizing agents.

In weiterer Ausarbeitung der Erfindung ist nun gefunden worden, daß man stets gute, in manchen Fällen auch schnellere und bessere Wirkungen erzielt, wenn statt der genannten einfachen Oxydationsmittel in bekannter Weise Gemische von solchen zur Anwendung bringt, bei welchen nicht in allen Fällen die saure Reaktion Voraussetzung für die Wirkung ist. Man kann Gemische von zwei oder mehreren verschiedenen Oxydationsmitteln, wie Hypochlorit und Permanganat, Hypochlorit und Chlorat, Persulfat und Permanganat, Chlorat mit Permanganat und Bichromat usw., verwenden. Die Geeignetheit der einen oder anderen Mischung ist nicht an bestimmte Regeln gebunden, sondern muß angesichts der außerordentlichen Verschiedenheit der zu behandelnden Ausgangsstoffe, die selbst bei gleicher Art noch Unterschiede je nach Herkunft, Alter usw. aufweisen, von Fall zu Fall durch Vorversuche im kleinen festgestellt werden.In further elaboration of the invention it has now been found that you always achieve good, in some cases faster and better effects, if, instead of the simple oxidizing agents mentioned, mixtures are used in a known manner of those used in which the acidic reaction does not occur in all cases A prerequisite for the effect is. One can use mixtures of two or more different Oxidizing agents such as hypochlorite and permanganate, hypochlorite and chlorate, persulfate and permanganate, chlorate with permanganate and bichromate, etc. The suitability one or the other mixture is not tied to certain rules, but rather must in view of the extraordinary diversity of the starting materials to be treated, which, even if they are the same species, still show differences depending on their origin, age, etc., can be determined from case to case by preliminary tests on a small scale.
