H. Adkins' Catalyst (I) Relationship between the Decomposition Temperatures of Copper Ammonium Chromate and the Activity of Copper-Chromium Oxide Catalyst

Abstract

The decomposition of copper ammonium chromate in the air under atmospheric pressure is completed at 280°. The decomposition temperature is independent of the addition of barium chromate or Kieselguhr and of the acidity or the alkalinity of the mother liquor in which the chromate is precipitated. Heating up to 280° is enough to produce a catalyst with high activity. At 7mm. Hg the decomposition temperature is lowered to 260°, but no appreciable increase in the activity of the catalyst is registered thereby.
