Effect of the Composition of Supported Copper-Containing Salt Catalysts on Their Activity in the Deacon Reaction: Dependence of the Rate of the Deacon Reaction on the Ratio between Copper and Potassium Chlorides in a Supported CuCl2–KCl Salt Catalyst

Аннотация

The effect of KCl/CuCl₂ molar ratios from 0 to 2.5 in the СuCl₂–KCl catalyst (support) on its activity in the Deacon reaction was studied by a gradientless method in a temperature range of 350–425°C. The essential role of the hydration processes of the salt catalyst components in the homogenization of a reaction layer was established. The experiments did not contradict the previously proposed reaction kinetics and mechanism. A possible explanation of the experimental results was given based on the polarization representations used earlier in the reaction mechanism.
