    Description / Table of Contents: On the Formation of CaF2 from Gaseous HF and Solid CaCl2The reaction 2{HF}g + {CaCl2}s → 2{HCl}g + {CaF2}s was studied under isothermal conditions in a constant HF atmosphere at 293, 393, and 443 K. Up to a degree of conversion x = ⅔ the rate of reaction is constant, when using powdered CaCl2. In view of the used CaCl2 the order of reaction is zero. This means, that the chemical reaction is limiting the velocity of the reaction in the range 0 ≤ x ≤ ⅔ and that the reaction takes place at a nearly constant surface. The activation energy was detected with 4.978 kJ/mol.
    Notes: Die Reaktion {HF}(g) + {CaCl2}(s) → 2{HCl}(g) + {CaF2}(s) wurde unter isothermen Bedingungen in einer konstanten HF-Atmosphäre bei 293, 393 und 443 K untersucht. Bis zu einem Umsatzgrad x = ⅔ ist die Reaktionsgeschwindigkeit bei Verwendung von CaCl2-Pulver in 1. Näherung konstant. Die Reaktion ist bezüglich des eingesetzten CaCl2 0. Ordnung. Daraus ergibt sich, daß die chem. Reaktion im Bereich 0 ≤ x ≤ ⅔ geschwindigkeitsbestimmend ist und an einer nahezu konstanten Oberfläche abläuft. Die Aktivierungsenergie wurde zu 4,978 kJ/mol bestimmt.
