Verfahren zur Gewinnung von Kautschuk oder kautschukähnlichen Massen.
Die Erfindung betrifft ein Verfahren zur Gewinnung von Kautschuk bzw. kautschuk- ähnlichen Produkten aus den dem Milchsaft ähnlichen Ausscheidungen der Apozinazeen, Artokarpazeen, Euphorbiazeen, Sapoteen, Lobeliazeen, Asklepiadeen und dgl.

in geringen Mengen befindet. Diese Mengen sind aber in manchen Fällen derart unzureichend, dass sich die Gewinnung des Kautschuks aus diesen Milchsäften bisher nicht lohnte.
Die Erfindung vermittelt die neue Erkenntnis, dass sich neben den geringen Mengen Kautschuk in den Ausscheidungen der genannten Pflanzen Kohlenwasserstoffe befinden, die sich mittels der iür die Hemiterpeue üblichen Polymerisationsverfahren in Kautschuk bzw. kautschuk- ähnlichen Massen überführen lassen. Es gelingt so, aus diesen Pflanzen in technischem Massstabe Kautschuk zu gewinnen.

eine Substanz zu ; welche geeignet ist, das Polymerisieren zu begünstigen, wie z. B. 5 kg Eisessig.
Man verrührt dieses Gemisch und setzt es auf die Dauer von vier Stunden im Autoklaven einer Temperatur von 140 bis C aus. worat,. f man die Losung durch ein feines Sieb filtriert, um die Beimischungen auszuscheiden.
Wenn die Mischung zu dickflüssig ist, fügt man solange Benzol hinzu, bis die Lösung eine sirupartige Konsistenz aufweist, um das Filtrieren zu erleichtern, t. m die an den Kohlenwasser- stolen durch Polymerisation erhaltene kautschukähnliche Substanz auszuscheiden, giesst man die filtrierte Flüssigkeit in Alkohol, worauf die elastische Masse sich niederschlägt, man sammelt

Process for the production of rubber or rubber-like compounds.
The invention relates to a method for obtaining rubber or rubber-like products from the excretions of the Apozinazeen, Artokarpazeen, Euphorbiazeen, Sapoteen, Lobeliazeen, Asklepiadeen and the like, which are similar to the milk sap.
EMI1.1
located in small quantities. In some cases, however, these quantities are so inadequate that it has not been worthwhile to extract the rubber from these milk juices.
The invention provides the new knowledge that, in addition to the small amounts of rubber, the excretions of the plants mentioned contain hydrocarbons which can be converted into rubber or rubber-like compounds by means of the polymerization processes customary for the hemiterpeue. It is thus possible to obtain rubber from these plants on a technical scale.
EMI1.2
a substance to; which is suitable to promote the polymerisation, such as e.g. B. 5 kg of glacial acetic acid.
This mixture is stirred and exposed to a temperature of 140 ° C. in the autoclave for four hours. worat ,. f the solution is filtered through a fine sieve in order to separate out the admixtures.
If the mixture is too thick, add benzene until the solution has a syrupy consistency to make it easier to filter, t. In order to excrete the rubber-like substance obtained by polymerisation on the hydrocarbons, the filtered liquid is poured into alcohol, whereupon the elastic mass is deposited and collected
