The applicability of supports such as LaF3, activated charcoal and Cr2O3 to the new reaction, CCl2F2 + 5 3NH3→HCN + 2HCl + 2HF + 1 3N2 was examined and it was found that TiO2 itself reacted with CFC12 to give carbon monoxide and carbon dioxide even at 673 K in addition to hydrogen cyanide formation. LaF3 did not react with CFC (chlorofluorocarbon) even at 823 K so that it could be considered suitable for use as a catalyst support. Au(1 wt.-%)/LaF3 and Pt(1 wt.-%)/LaF3 were effective for hydrogen cyanide formation and hydrogen cyanide selectivity reached 77-78% at 823 K. Activated charcoal was also suitable for use as a catalyst support and hydrogen cyanide was formed selectively (72-84%) over Rh(1 wt.-%)/AC and Pd(1 wt.-%)/AlF3/AC catalysts at 823 K.
