Patentirt im Deutschen Reiche vom 16. August 1901 ab.Patented in the German Empire on August 16, 1901.
J. Riban (Compt. rend. 95, S. 1161 ff.) hat gefunden, dafs man aus Tricalciumphosphat durch Mischen mit Kohle und Ueberleiten von Chlor und Kohlenoxyd in der Wärme Phosphoroxychlorid darstellen kann. Aus der Thatsache, dafs weder durch Kohle noch durch Kohlenoxyd, jedes für sich allein als Reductionsmittel angewendet, beim Behandeln mit Chlor aus TricalciumphosphatPhosphoroxychlorid erhalten wird, sondern nur Phosphor, Phosphortrichlorid oder Phosphorpentachlorid je nach Stärke des Chlorstroms, schliefst Riban, dafs ein Zusammenwirken der Kohle und des Kohlenoxyds in der Weise stattfindet, dafs die erstere als Ueberträger der reducirenden Wirkung des letzteren dient. Er giebt dieser Meinung auch durch die von ihm aufgestellten Formeln Ausdruck, in denen nur das Kohlenoxyd als Reductionsmittel erscheint:J. Riban (Compt. Rend. 95, pp. 1161 ff.) found that tricalcium phosphate can be obtained by mixing with charcoal and passing over Chlorine and carbon monoxide can represent phosphorus oxychloride in the heat. From the fact that neither by coal nor by carbon monoxide, each of them alone as a reducing agent applied, obtained when treating with chlorine from tricalcium phosphate phosphorus oxychloride but only phosphorus, phosphorus trichloride or phosphorus pentachloride depending on the strength of the Stream of chlorine, Riban concludes that there is a co-operation of coal and carbon dioxide takes place in such a way that the former as a carrier of the reducing effect of the the latter serves. He also expresses this opinion through the formulas he has drawn up, in which only the carbon dioxide appears as a reducing agent:
ι. P2 O5 (Ca O)3 + 2 C O + 4 Cl =ι. P 2 O 5 (Ca O) 3 + 2 CO + 4 Cl =
P2OsCaO + 2 COs + 2Ca ch-P 2 OsCaO + 2 COs + 2Ca c h-
2. P2O5CaO + 4 C O + 8 C/ = 2. P 2 O 5 CaO + 4 C O + 8 C / =
2 PO Cl3 -f- Ca CL2 + 4 C O2. 2 PO Cl 3 -f- Ca CL 2 + 4 CO 2 .
Demgegenüber wurde nun gefunden, dafs man in der Phase, die durch die zweite Formel ausgedrückt wird, das Kohlenoxyd durch Kohle ersetzen kann, dafs man also durch Kohle allein Phosphoroxychlorid erhalten kann, sobald man von einem Metaphosphat direct ausgeht. On the other hand, it has now been found that in the phase represented by the second formula is expressed that carbon oxide can be replaced by charcoal, that is to say by charcoal only phosphorus oxychloride can be obtained as soon as one starts directly from a metaphosphate.
Man bereitet sich z. B. in der bei der Darstellung von Phosphor üblichen Weise (Behandeln von Tricalciumphosphat mit Schwefelsäure, Versetzen der vom Gips abgesaugten Lösung des primären Calciumphosphats mit Kohle, Eindampfen und schwaches Glühen) eine Kohle enthaltende Schmelze von Calciummetaphosphat. Dieselbe wird zerkleinert und in einem geeigneten Apparat, welcher mit Kühler und Vorlage versehen ist, schwach geglüht. Gleichzeitig wird ein Strom trockenen Chlors eingeleitet. Alsbald sammelt sich in der Vorlage ein Flüssigkeit an, welche nach nochmaligem Destilliren reines Phosphoroxychlorid darstellt.One prepares z. B. in the usual way in the representation of phosphorus (treat of tricalcium phosphate with sulfuric acid, addition of the primary calcium phosphate solution extracted from the gypsum Coal, evaporation and faint glow) a coal-containing melt of calcium metaphosphate. The same is crushed and lightly calcined in a suitable apparatus which is provided with a cooler and receiver. At the same time a stream of dry chlorine is introduced. Immediately collects in the Submission of a liquid which, after further distillation, is pure phosphorus oxychloride represents.
Die technischen Vortheile vorliegender Erfindung bestehen darin, dafs einmal die Apparatur eine einfachere sein kann, indem nur ein Gas eingeführt zu werden braucht. Durch das Fortfallen des brennbaren und giftigen Kohlenoxyds wird auch eine gröfsere Betriebssicherheit herbeigeführt. Ferner tritt eine bedeutende Ersparnifs an Chlor ein, indem gegenüber dem Triphosphat zwei Drittel Calcium weniger in Chlorcalcium überzuführen sind. Die zu erhitzenden, die Kohlephosphatmischung enthaltenden Gefäfse können relativ kleiner sein bezw. gestatten eine bessere Ausnutzung, weil das Metaphosphat mehr Phosphor enthält wie das Triphosphat.The technical advantages of the present invention consist in the fact that, on the one hand, the apparatus a simpler one, in that only one gas needs to be introduced. By the Elimination of the flammable and poisonous carbon monoxide also increases operational safety brought about. Furthermore, there is a considerable saving in chlorine, in that compared with the Triphosphate two thirds of calcium less need to be converted into calcium chloride. The ones to be heated the vessels containing the carbon phosphate mixture can be relatively smaller or. allow better utilization because the metaphosphate contains more phosphorus than the triphosphate.
