✦ Synopsis


A method is described for the determination of carbon in non-conducting synthetic catalysts. Carbon is oxidized in a high frequency induction furnace and the evolved carbon dioxide is absorbed in a solution of barium hydroxide. The change in conductivity of this solution is directly proportional to the carbon burned. The method is rapid and reasonably precise at the 0.05% carbon level. Rt~SUM]~ Une mdthode est d6crite pour le dosage rapide du carbone dans des catalyseurs. On proc6de par combustion darts un four k induction, k haute fr6quence. L'anhydride carbonique obtenu est ab-sorb6 darts une solution d'hydroxyde de baryum. La variation de conductibilit6 de cette solution est proportionnelle ~. la quantit6 de carbone brfll6e. La m(thode est rapide et d'une pr6cision satisfaisante au niveau de 0.o5% de carbone. ZUSAMMENFASSUNG Beschreibung einer Schnell-methode zur Bestimmung des Kohlenstoffs in Katalysatoren durch Verbrennung in einem Hochfrequenz-Induktionsofen. Das gebildete Kohlendioxyd wird in Barytlauge absorbiert und die Anderung der Leitf~higkeit gemessen; diese ist dem Kohlenstoffgehalt direkt proportional. Die Exaktheit der Methode ist bei o.o 5 % Kohlenstoffgehalt zufriedenstellend.
