Abstract
The present disclosure provides azeotrope or azeotrope-like compositions including trifluoroiodomethane (CF3I) and trifluoroacetyl chloride (CF3COCl), and a method of forming an azeotrope or azeotrope-like composition comprising the step of combining trifluoroacetyl chloride (CF3COCl) and trifluoroiodomethane (CF3I) to form an azeotrope or azeotrope-like composition.
Claims20
A composition comprising an azeotrope or azeotrope-like composition consisting essentially of effective amounts of trifluoroacetyl chloride (CF3COCl) and trifluoroiodomethane (CF3I).
A method of forming an azeotrope or azeotrope-like composition comprising the step of combining trifluoroacetyl chloride (CF3COCl) and trifluoroiodomethane (CF3I) to form an azeotrope or azeotrope-like composition consisting essentially of trifluoroacetyl chloride (CF3COCl) and trifluoroiodomethane (CF3I) having a boiling point between about −46.0° C. and about 90.0° C. at a pressure of between about 4.9 psia and about 348 psia.
A method of separating trifluoroacetyl chloride (CF3COCl) and trifluoroiodomethane (CF3I) from a primary composition comprising trifluoroacetyl chloride (CF3COCl), trifluoroiodomethane (CF3I) and at least one impurity, comprising the steps of:
- forming, within the primary composition, a secondary composition which is an azeotrope or azeotrope-like composition consisting essentially of effective amounts of trifluoroacetyl chloride (CF3COCl) and trifluoroiodomethane (CF3I) having a boiling point between about −46.0° C. and about 90.0° C. at a pressure of between about 4.9 psia and about 348 psia;
- and
- separating the secondary composition from the primary composition and the at least one impurity.
