Abstract[German]
Die Erfindung betrifft ein Verfahren zur Herstellung von Phosphor-Chlor-Verbindungen dadurch gekennzeichnet, dass man i. ein Phosphor-Sauerstoffverbindungs-haltiges Material in Gegenwart von Tetrachlorethen bei einer Temperatur von 500 bis 1000°C umsetzt und ii. die gebildeten Phosphor-Chlor-Verbindungen, insbesondere Phosphoroxychlorid im Abgasstrom ableitet und isoliert.[English]
The invention relates to a process for producing phosphorus-chlorine compounds, characterized by the steps of i. reacting a phosphorus-oxygen compound-containing material in the presence of tetrachloroethene at a temperature of 500 to 1000°C and ii. removing and isolating the formed phosphorus-chlorine compounds, in particular phosphorus oxychloride, in the off-gas stream.[French]
L'invention concerne un procédé de production de composés de phosphore-chlore, caractérisé en ce que i) l'on fait réagir une matière contenant un composé oxygéné de phosphore en présence de tétrachloroéthène à une température comprise entre 500 et 1000 °C et ii) l’on dérive et isole les composés de phosphore-chlore formés, en particulier l'oxychlorure de phosphore dans le flux de gaz résiduaires.
