Description

Verfahren zum Herstellen von niedrigeren Titanhalogeniden durch Reduktion von Titantetrachlorid mit gasförmigen Reduktionsmitteln Es ist bekannt, Titantetrahalogenid mit gasförmigen Reduktionsmitteln zu niedrigeren Titanhalogeniden zu reduzieren. Als solche Reduktionsmittel sind Wasserstoff und Metalldampf bekannt. Diese Verfahren sind bisher nur unter Atmosphärendruck ausgeführt worden.Process for producing lower titanium halides by reduction of titanium tetrachloride with gaseous reducing agents It is known titanium tetrahalide to reduce to lower titanium halides with gaseous reducing agents. As such reducing agents, hydrogen and metal vapor are known. These procedures have so far only been carried out under atmospheric pressure.

Es wurde nun gefunden, daß diese Verfahren zu besseren Ergebnissen, nämlich zu einer vollständigeren Umsetzung, führen, wenn die Reduktion mit gasförmigen Reduktionsmitteln unter höherem Druck durchgeführt wird. Dies hat den weiteren Vorteil, daß bei niedrigeren Temperaturen gearbeitet werden kann.It has now been found that this method leads to better results, namely lead to a more complete conversion, if the reduction with gaseous Reducing agents is carried out under higher pressure. This has the further advantage that you can work at lower temperatures.

Wenn Wasserstoff als Reduktionsmittel verwendet wird, ist es weiterhin aus wirtschaftlichen Gründen zweckmäßig, solchen Wasserstoff zu verwenden, der Kohlenmonoxyd enthält, da die Reduktion mit diesem Gasgemisch in der gleichen Weise durchgeführt werden kann, als wenn reiner Wasserstoff verwendet wird und da dieses Gasgemisch technisch in großen Mengen zur Verfügung steht.When hydrogen is used as a reducing agent, it continues to be For economic reasons it is expedient to use such hydrogen, carbon monoxide contains, since the reduction is carried out in the same way with this gas mixture can be as if pure hydrogen is used and because this gas mixture is technically available in large quantities.

Eine weitere bevorzugte Ausführungsforen der Erfindung liegt darin, bei Temperaturen und Drücken zii arbeiten, bei denen Titantetrachlorid noch nicht kondensiert, beispielsweise bei der Reduktion mit Wasserstoff bei einem Druck von 15 atü und einer Temperatur über 500° C.Another preferred embodiment of the invention is work at temperatures and pressures zii at which titanium tetrachloride is not yet condensed, for example in the reduction with hydrogen at a pressure of 15 atü and a temperature above 500 ° C.
