Zusammenfassung

Die gleichzeitige gravimetrische Mikrobestimmung von Kohlenstoff, Wasserstoff und Chlor (oder Brom) wird beschrieben. Als Katalysator dient gekörntes Co3O4 bei 750° C. Das Halogen wird in einem mit Silberschwamm gefüllten Quarzröhrchen quantitativ zurückgehalten. Wasser und Kohlendioxid werden wie üblich in Preglschen Röhrchen absorbiert und gewogen. Die Gesamtdauer der Analyse beträgt 35 Minuten. Die Fehlergrenze liegt innerhalb ± 0,3%.

Simultaneous gravimetric microdetermination of carbon, hydrogen and chlorine (or bromine) in organic substances

Summary

The simultaneous gravimetric microdetermination of carbon, hydrogen and chlorine (or bromine) are described. Granular Co3O4 serves as catalyst at 750° C. The halogen is quantitatively retained in a quartz tube packed with silver sponge. Water and carbon dioxide are absorbed as usual in a small Pregl tube and weighed. The entire analysis consumes 35 minutes. The limit of error lies within ± 0.3%.
