Abstract

DTA analysis of carrier-CuCl2, KCl catalysts with total active salt contents of from 17.68 to 33.27%, and with Cu∶K molar ratios of from 0.691 to 0.922, revealed a number of endothermic processes within the temperature range 293–773 K. The extents of these processes depended on the total salt content and the Cu∶K molar ratio. The influence of the carrier on the active phase constitution was observed. >

Zusammenfassung

Die DTA-Anlyse von Trägerkatalysatoren mit CuCl2KCl mit einem Aktivsalzgesamtgehalt von 17.68 bis 33.27% und einem molaren Verhältnis (Cu zu K) von 0.691 bis 0.922 zeigte, daß beim Erhitzen der Katalysatoren im Temperaturbereich von 293–773 K eine Reihe endothermer Vorgänge ablaufen. Die Größe dieser endothermen Effekte ist abhängig vom Aktivsalzgesamtgehalt und vom molaren Verhältnis Cu∶K. Der Einfluß des Trägermateriales auf die Konstitution der aktiven Phase wurde untersucht.
