Description

Verfahren zum Konzentrieren von Kautschukmilchsaft. Das Verfahren besteht in einer Konzentrierung von Kautschukmilchsaft (Latex) durch Hinzufügung von Auszügen pflanzlichen oder tierischen Ursprungs, welche die Wirkung haben, die Bildung zweier getrennter Schichten Nerv orzubriiien. -,vobei die eine Schicht gegenüber dein ursprünglichen Latex erheblich an Kautschuksubstanz angereichert wird.Method for concentrating rubber milk juice. The procedure consists in a concentration of rubber milk juice (latex) by adding it of extracts of vegetable or animal origin which have the effect that Formation of two separate layers of nerve failure. -, with the one layer opposite your original latex is significantly enriched in rubber substance.

Es wurde gefunden, daß eine lteilie von Pflanzenschleimen, insbesondere Carragheen-.Moos, Isländisch-Moos u. dgl., schon in sehr geringen 1Iengen in Gestalt ihrer wäßrigen Auszüge dem Latex hinzugefügt, die Wirkung haben, innerhalb einiger Zeit die Bildung einer Trennungsschicht hervorzurufen, wobei die eine, im allgemeinen die untere Schicht nur wenig oder gar keine Kautschuksubstanz enthält, während die andere Schicht die Kautschuksubstanz in konzentrierter Form enthält und bei geeigneter Wahl der hinzugefügten Stoffmengen bis zu dicksahniger Konsistenz gebracht werden kann.It has been found that a portion of plant mucilages, in particular Carragheen moss, Icelandic moss and the like, even in very small lengths their aqueous extracts added to the latex, which have effect within some Time to cause the formation of a release layer, one, in general the lower layer contains little or no rubber substance, while the other layer contains the rubber substance in concentrated form and when suitable Choice of the added amounts of substance can be brought up to a thick-cream consistency can.

Eine Koagulation der Latexteilchen tritt dabei im allgemeinen nicht ein, im Gegensatz zu anderen Konzentrationsverfahren, wie beispielsweise durch Zusatz von Kaliumkarbonat oder sonstiger hygroskopischer Salze oder durch Eindampfen im Vakuum usw. plan vermischt beispielsweise io ccm einer iprozentigen wäßrigen Carragheenmooslüsung bei Zimmertemperatur mit etwa Go bis 70 ccm Latex je nach dessen Konzentration, erwärmt, um eine schnellere vollkommene Schichtenabsonderung zii erzielen, zweckmäßig i bis mehrere Stunden auf 4o bis 6o° und beobachtet dann die Bildung zweier scharf gesonderter Schichten, deren untere nur wenige Prozent, meist weniger als 5 Prozent Kautschuksubstanz enthält, während der Kautschukgehalt der oberen Schicht gegenüber dem gewöhnlichen Latex auf etwa die doppelte Konzentration angereichert wurde.Coagulation of the latex particles does not generally occur, in contrast to other concentration methods, such as, for example, by adding potassium carbonate or other hygroscopic salts or by evaporation in a vacuum, etc., mixed flat, for example 10 ccm of an aqueous carragheen moss solution at room temperature with about Go to 70 ccm of latex, depending on its concentration, warmed up in order to achieve a more rapid and complete separation of the layers, expediently for 1 to several hours at 40 to 60 ° and then observes the formation of two sharply separated layers, the lower of which contains only a few percent, usually less than 5 percent rubber substance , while the rubber content of the upper layer was enriched to about twice the concentration compared to the ordinary latex.

Man kann auch durch andere Substanzen als Pflanzenschleime, wie Leim und Gelatine, derartige Schichtenbildungen erzeugen, ebenso kann man sowohl clie -elatinierten Pflanzenschleime wie auch Leim und Gelatinegele u. dgl. derart benutzen, daß man Latex mit ihnen in Berührung bringt und durch Wasseraufnahme seitens der Gele eine Konzentrierung herbeiführt. 1#erner kann man die genannten Stoffe auch in fester Form dein Latex hinzufügen und dadurch eine Konzentrierung bewirken.You can also use substances other than plant mucilage, such as glue and gelatin to produce such layer formations, one can also use both clie -elatinized plant slimes as well as glue and gelatin gels and the like in such a way that they are used that one brings latex into contact with them and by absorbing water on the part of the Gels cause concentration. You can also use the substances mentioned above add your latex in solid form and thereby cause a concentration.
