Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
1 . 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. 2 . The process of claim 1 , wherein in the providing step, the mole ratio of the trifluoroacetyl chloride to the hydrogen iodide is from about 1:10 to about 10:1. 3 . The process of claim 1 , wherein in the providing step, a weight ratio of the catalyst to the trifluoroacetyl chloride may be from about 0.001:1 to about 0.5:1. 4 . The process of claim 1 , wherein the catalyst is selected from the group consisting of silicon carbide, activated carbon, carbon molecular sieves, and combinations thereof. 5 . The process of claim 1 , wherein in the reacting step, the trifluoroacetyl chloride, the hydrogen iodide, and the optional catalyst are at a temperature from 0° C. to 200° C. 6 . A process for producing trifluoroacetyl iodide (TFAI) in a liquid phase reaction, the process comprising: mixing trifluoroacetyl chloride, hydrogen iodide, and an optional catalyst; and heating the trifluoroacetyl chloride, hydrogen iodide, and an optional catalyst to produce trifluoroacetyl iodide and hydrogen chloride. 7 . The process of claim 6 , further including separating the trifluoroacetyl iodide from the hydrogen chloride, trifluoroacetyl chloride, and hydrogen iodide. 8 . The process of claim 6 , wherein the process is a continuous process. 9 . The process of claim 6 , wherein the process is a batch process. 10 . The process of claim 6 , wherein the catalyst is selected from the group consisting of silicon carbide, activated carbon, carbon molecular sieves, and combinations thereof. 11 . The process of claim 6 , wherein in the reacting step, the trifluoroacetyl chloride, the hydrogen iodide, and the optional catalyst are at a temperature from 0° C. to 200° C. 12 . The process of claim 6 , wherein in the reacting step, the trifluoroacetyl chloride, the hydrogen iodide, and the optional catalyst are at a pressure of 5 psig to 500 psig.
