Abstract
The present disclosure provides a process for making trifluoroacetyl iodide (TFAI) in a liquid phase reaction. Specifically, the present disclosure provides a liquid phase reaction of trifluoroacetyl chloride (TFAC) and hydrogen iodide (HI), with or without a catalyst, to form trifluoroacetyl iodide (TFAI). The reaction may be performed at ambient or elevated temperatures.
Claims15
A process for producing trifluoroacetyl iodide (TFAI) in a liquid phase reaction, the process comprising:
- providing trifluoroacetyl chloride, hydrogen iodide, and an optional catalyst;
- reacting the trifluoroacetyl chloride and hydrogen iodide to provide trifluoroacetyl iodide at a temperature from 25° C. to 90° ° C.,
- and
- wherein the process has a selectivity for trifluoroacetyl iodide that is greater than 90%.
