Impurities such as sulfur dioxide (SO.sub.2) are removed from trifluoroacetyl chloride (TFAC) through distillation, adsorption, or a combination thereof, and/or including the formation of an azeotrope or azeotrope-like composition including effective amounts of sulfur dioxide (SO.sub.2) and trifluoroacetyl chloride (TFAC). The trifluoroacetyl chloride (TFAC) thus purified may then be used in the manufacture of trifluoroiodomethane (CF.sub.3I). Also disclosed are azeotropes and azeotrope like compositions of sulfur dioxide (SO.sub.2) and trifluoroacetyl chloride (TFAC).
