Description
Verfahren zur Herstellung von Titandichlorid Titandichlorid wird im allgemeinen durch Reduktion von Titantebrachloridhergestellt; als Reduktionsmittel sind sowohl Metalle einschließlich des Titans selbst als auch Wasserstoff empfohlen worden. Da zur Gewinnung von Titanmetall durch Disproportionierung des Dichlorids Titan als Reduktionsmittel selbstverständlich ausscheidet, andere Metalle aber zu Titandichloridgemischen mit fremdem Chlorid führen, bietet die Reduktion des Tetrachlorids mit Wasserstoff entscheidende Vorteile, sobald ein genügend leistungsfähiges Verfahren dafür zur Verfügung steht. Bisher sind aber zur Durchführung dieser Reaktion nur Vorschläge bekanntgeworden, die für eine Anwendung im gewerblichen Ausmaß und Dauerbetrieb nicht geeignet sind. Es wurde danach das Reaktionsgemisch in einem Quarzrohr erhitzt oder elektrisch aktiviert in der sogenannten stillen elektrischen Entladung oder - elektrodenlos - im hochfrequenten elektromagnetischen Wechselfeld.Process for the production of titanium dichloride Titanium dichloride is used in generally made by the reduction of titanium brachloride; as a reducing agent Both metals, including titanium itself, and hydrogen are recommended been. As for the extraction of titanium metal by disproportionation of the dichloride Of course, titanium is eliminated as a reducing agent, but other metals do Titanium dichloride mixtures with foreign chloride lead to the reduction of the tetrachloride decisive advantages with hydrogen, as soon as a sufficiently efficient process is available for this. So far, however, are only used to carry out this reaction Proposals have become known for an application on a commercial scale and continuous operation are not suitable. The reaction mixture was then heated in a quartz tube or electrically activated in the so-called silent electrical discharge or - electrodeless - in a high-frequency electromagnetic alternating field.
Ein demgegenüber sehr einfacher Weg zur Herstellung reinen Titandichlorids wurde nun darin gefunden, daß man, von gewöhnlicher Temperatur ausgehend, in einem Gemisch von Titantetrachlorid und Wasserstoff, dessen Anteil in dem Gasgemisch um ein geringes, in der Regel etwa um 10%, größer gewählt wird, als er sich stöchiometrisch im Verhältnis zum Titantetrachlorid errechnet, damit die Bildung von Titantrichlorid unterbleibt, unter einem Gesamtdruck zwischen 2 und 30 Torr, vorzugsweise zwischen 6 und 15 Torr, eine elektrische Büschelentladung erzeugt, wobei man zweckmäßigerweise das Gas stetig den Entladungsraum durchströmen läßt. Als elektrisches Gerät benötigt man dazu lediglich einen Transformator, der bei einem Spannungsverhältnis von etwa 1:100 an ein gewöhnliches Wechselstromnetz angeschlossen werden kann. Die Reinheit des Produktes wird dabei trotz Anwendung von Innenelektroden nicht gemindert, wenn man diese aus Titanmetall oder ersatzweise aus einem sehr inerten Metall, z. B. Platin, herstellt. Die Unempfindlichkeit der elektrischen Ausrüstung gewährleistet störungsfreien Dauerbetrieb, der Größe der technischen Anlage sind bei diesem Verfahren keine Grenzen gesetzt, und die Werkstoffwahl für die Gefäßwände bereitet infolge der niedrigen Temperatur des Reaktionsraumes keine Schwierigkeiten.In contrast, a very simple way of producing pure titanium dichloride has now been found in the fact that, starting from ordinary temperature, in a Mixture of titanium tetrachloride and hydrogen, the proportion of which in the gas mixture is around a small one, usually around 10%, is chosen to be larger than it is stoichiometric calculated in relation to the titanium tetrachloride, thus the formation of titanium trichloride omitted, under a total pressure between 2 and 30 torr, preferably between 6 and 15 Torr, an electric brush discharge is generated, which is expediently lets the gas flow steadily through the discharge space. Required as an electrical device all you have to do is use a transformer that works at a voltage ratio of about 1: 100 can be connected to a normal alternating current network. The purity of the product is not reduced despite the use of internal electrodes if they can be made from titanium metal or, alternatively, from a very inert metal, e.g. B. Platinum. The insensitivity of the electrical equipment is guaranteed Trouble-free continuous operation, the size of the technical system are in this process No limits are set, and the choice of material for the vessel walls prepares as a result the low temperature of the reaction chamber poses no problems.
