ABSTRACT:
The catalyst consists essentially of a calcium fluoride matrix and a thermally stable copper-containing phase as produced by coprecipitation of calcium fluoride and copper fluoride and/or calcium hydroxide and copper oxide, in presence of alkali metal or ammonium ion. The coprecipitate is thoroughly dried and heated at elevated temperature; followed, if the coprecipitate is in the form of hydroxide and/or oxide, by conversion of such hydroxide and oxide to fluoride.
The preferred alkali metal ion is potassium.
The most active and stable catalysts show by X-ray diffraction a pattern including lines characteristic of calcium fluoride and additional lines indicative of a face-centered cubic unit cell having unit dimension of about 8.1-8.4 A.
The catalyst operates at about 200.degree.-550.degree. C. depending to some extent on the substrate.
