Dissociation, disproportionation, dismutation and exchange reactions

Heating COCIF between 400-600 C in an autoclave induces disproportionation, as represented by Equation (16.4) [1454]  

The effect of the disproportionation reaction. Equation (16.4), is that, in reactions of phosgene which can produce both COFj and COCIF, high temperatures favour the formation of COFj and low temperatures favour the formation of COCIF. 

A secondary dismutation reaction. Equation (16.5), may also occur [899], and the conditions for the synthesis of dichlorodifluoromethane by this route have been optimized, but the yield remains low [900,902,905]  

When heated to 425 C for 19 h, in the presence of a silicate-free activated carbon catalyst impregnated with iron(III) chloride, COCIF disproportionates to the extent of 13% into 

In analogous reactions to Equation (16.5), heating COCIF with COBtj, COFj or COCij in an autoclave produces CBfjClF, CCIF, or CCI3F, respectively [902,905].
