KAISERLICHESIMPERIAL
PATENTAMT,PATENT OFFICE,
Im Patent 287787 ist ein Verfahren zur Darstellung von kautschukartigen Substanzen beschrieben, welches darin besteht, daß Butadien und seine Homologen mit Metallen, wie Natrium, bei Gegenwart von Kohlensäure behandelt werden.In patent 287787 is a method for the preparation of rubbery substances described, which consists in the fact that butadiene and its homologues with metals such as Sodium, to be treated in the presence of carbonic acid.
Es hat sich nun gezeigt, daß es unter Umständen vorteilhaft sein kann, Gemische oder Legierungen von Alkalimetallen unter sich oder mit anderen Metallen zu verwenden. Die Polymerisation kann in diesen Fällen rascher verlaufen als bei Verwendung von einzelnen Alkalimetallen. It has now been shown that it can be advantageous under certain circumstances, mixtures or To use alloys of alkali metals among themselves or with other metals. The polymerization can run faster in these cases than when using individual alkali metals.
. Beispiel 1.. Example 1.
100 Teile 2 · 3-Dimethyl-i · 3-butadien werden mit 5 Teilen feinem Natriumdraht und 5 Teilen Eisenfeilspänen in einem mit Kohlensäure gefüllten Gefäß etwa 3 bis 4 Tage geschüttelt, bis die ganze Masse in ein schwarzes voluminöses Produkt übergeführt ist; dieses wird durch Eintragen in Wasser, Alkohol o. dgl. von Alkalimetall und zugleich mechanisch von einem Teil des Eisens befreit; der Rest des letzteren kann durch Nachbehandeln mit Salzsäure entfernt werden.100 parts of 2 · 3-dimethyl-i · 3-butadiene will be with 5 parts of fine sodium wire and 5 parts of iron filings in a carbonated one Vessel shaken for about 3 to 4 days, until the whole mass turns into a black voluminous Product is transferred; this is done by adding it to water, alcohol or the like. from alkali metal and at the same time mechanically freed from some of the iron; the rest of the the latter can be removed by treating with hydrochloric acid.
Wendet man andere Metalle an, wie z. B. Zink, Zinn, Blei, Nickel usw., so kann man im wesentlichen in gleicher Weise arbeiten, ebenso wenn ein anderer Kohlenwasserstoff der Butadienreihe verwendet wird.If you use other metals, such as. B. zinc, tin, lead, nickel, etc., so you can work essentially in the same way, even if a different hydrocarbon the butadiene series is used.
Beispiel 2. ■ - . . tExample 2. ■ -. . t
100 Teile 2 · 3-Dimethyl-i · 3-butadien werden mit so viel flüssigem oder festem feingepulverten Natriumamalgam, als etwa 2 Teilen Natrium entspricht, in einer Kohlensäureatmosphäre einige Tage geschüttelt, bis die Masse schwarz und fest geworden ist. Nach dem Eintragen in Wasser usw. kann das weiß gewordene Produkt von dem noch anhaftenden Quecksilber durch Zentrifugieren befreit werden. Analog kann man bei Benutzung anderer Butadiene sowie anderer Natriumlegierungen, beispielsweise Bleinatrium, verfahren. .-■-..100 parts of 2 · 3-dimethyl-i · 3-butadiene are finely powdered with as much liquid or solid Sodium amalgam, equal to about 2 parts sodium, in a carbonic acid atmosphere Shaken for a few days until the mass has turned black and solid. After this The product which has become whitened can be removed from the still adhering product when it is added to water, etc. Mercury can be freed by centrifugation. Similarly, when using other butadienes and other sodium alloys, for example lead sodium, proceed. .- ■ - ..
Die nach vorliegendem Verfahren gewonnenen Produkte lassen sich ebenso wie diejenigen des Hauptpatents entsprechend dem Zusatzpatent 294816 zur Polymerisation weiterer Mengen von Butadienen benutzen.The products obtained by the present process can be just like those of the main patent corresponding to the additional patent 294816 for the polymerization of others Use amounts of butadienes.
