Description

Verfahren zur Herstellung von Verbindungen aus Selen und Kohlenstoff Wenn man nach einer bekannten Arbeitsweise feuchten Tetrachlorkohlenstoff auf Phosphorpentaselenid bei Rotglut emnwirken ließ, erhielt man eine geringe Menge einer Flüssigkeit, die höchstens 20/0 Selenkohlenstoff enthielt. Verbindungen des Selens mixt Kohlenstoff wurden in reiner Form bis jetzt nicht hergestellt.Process for the preparation of compounds from selenium and carbon If you use a known method of moist carbon tetrachloride on phosphorus pentaselenide allowed to have an effect in red heat, a small amount of a liquid was obtained which Contained at most 20/0 selenium carbon. Compounds of selenium mixes carbon have not yet been produced in their pure form.

Es wurde nun gefunden, daß man derartige Verbindungen in wesentlich einfacherer Weise und erheblich besserer Ausbeute erhalten kann, wenn man Selenwasserstoff bei Temp.eraturmen zwischen 30o und 700°, zweckmäßig bei etwa 5oo°, auf Halogenide des Kohlenstoffs, beispielsweise Tetrachlorkohlenstoff, einwirken läßt. Man verfährt vorteilhafterweise dabei so, daß man das Kohlenstoffhalogenid in dampfförmigem Zustand zusammen mixt Selenwasserstoff und gegebenenfalls mit einem indifferenten Führungsgas gemischt, durch erhitzte Röhren leitet. Das entstandene Reaktionsprodukt, ein Gemisch aus einem Seelenkohlenstoff, Selenhalogenid und unverändertem Kohlenstoffhalogenid, kann durch Abkühlen kondensiert und in bekannter Weise, z. B. durch Wasserdampfdestillation und Fraktionieren weiter gereinigt werden. Beisspiel Ein mixt Tetrachlorkohlenstoffdampf und ein mit Selenwasserstoffdampf beladener Stickstoffstrom werden in einem solchen Verhältnis gemischt, daß das entstandene Mischgas das Verhältnis C C14 : a H2Se aufweist. Diese Mischung wird durch ein auf 5oo° erhitztes Röhrensystem geleitet und dann in einer Vorlage ,gekühlt. Das auf diese Weise erhaltene Kondensat besteht aus einem Gemisch von unverändertem Tetrachlorkohlenstoff, Selenkohlenstoff und Selenchloriden. Es wird der Wasserdampfdestillation unterworfen und dann bei gewöhnlichem und nachfolgend unter vermindertem Druck fraktioniert. Schließlich erhält man Selenkohlenstoff von der Formel C S-e2, der einen Schmelzpunkt von - 45,5' besitzt und unter 76omm Druck bei 1z4° siedet.It has now been found that such compounds are essential Easier way and considerably better yield can be obtained if you use hydrogen selenide at Temp.eraturmen between 30o and 700 °, expediently at about 500 °, on halides of carbon, for example carbon tetrachloride, can act. One moves advantageously in such a way that the carbon halide is in the vaporous state hydrogen selenide mixes together and optionally with an inert guide gas mixed, passed through heated tubes. The resulting reaction product, a mixture from a soul carbon, selenium halide and unchanged carbon halide, can be condensed by cooling and in a known manner, for. B. by steam distillation and fractionation can be further purified. Example A mixes carbon tetrachloride vapor and a nitrogen stream loaded with hydrogen selenide vapor are contained in such a stream Mixed ratio that the resulting mixed gas has the ratio C C14: a H2Se having. This mixture is passed through a tube system heated to 500 ° and then in a template, chilled. The condensate obtained in this way exists from a mixture of unchanged carbon tetrachloride, carbon selenium and Selenium chlorides. It is subjected to steam distillation and then ordinary and subsequently fractionated under reduced pressure. Finally, one obtains carbon selenium of the formula C S-e2, which has a melting point of -45.5 'and below 76omm Pressure boils at 1z4 °.
