| titleOfInvention | Preparation of fluorinated perhaloaldehydes |
| abstract | Fluorinated perhaloacetaldehydes are made by heating, in the vapour phase at 200-500 DEG C., anhydrous hydrogen fluoride and a perhaloacetaldehyde in which the halogens are Cl or F, at least one being Cl, using at least one mole of hydrogen fluoride per mole of perhaloacetaldehyde, in the presence of an activated anhydrous chromium (III) oxide catalyst. It is usual to employ hydrogen fluoride in an excess of the stoichlometric amount required, as the degree of fluorination is primarily dependent upon the reaction temperature, catalyst and flow rate. The fluorinated perhaloacetaldehydes are obtained as complexes with hydrogen fluoride which can be decomposed by treatment with activated sodium fluoride. Examples relate to trifluoroacetaldehyde. |
