Carbonyl fluoride

Carbonyl fluoride is produced from trifluoromethanol. The latter is produced in turn by protonation of in-situ generated trifluoromethoxide. Of potential relevance to atmospheric chemistry, tetrafluoromethane hydrolyses to carbonyl fluoride: : Carbonyl fluoride can also be prepared by reaction of phosgene with hydrogen fluoride as well as the fluorination of carbon monoxide, although the latter tends to result in over-fluorination to carbon tetrafluoride. The fluorination of carbon monoxide with silver difluoride is convenient: : ==Reactions==

Carbonyl fluoride readily hydrolyzes to carbon dioxide and hydrogen fluoride: : When produced in situ, carbonyl fluoride converts carboxylic acids to acyl fluorides: : ==Safety==

Carbonyl fluoride is very toxic with a recommended exposure limit of 2 ppm as an 8-hour time weighted average and a 5 ppm as a short-term (15-minute average) exposure, where 1 ppm = 2.70 mg of carbonyl fluoride per 1 m3 of air. ==References==
