CAS Number:756-13-8
Molecular formula:C6F12O
Molecular Weight:316.04

Perfluorohexanone is used as a wet cleaning agent for steam reactors and steam reactor components, as well as for cleaning unwanted deposits accumulated in gas phase reactors, etching dielectric or metallic materials in gas phase reactors and doping various materials in gas phase reactors. It can be prepared by the reaction of Hexafluoropropylene and Pentafluoropropanoyl fluoride.

Reaction Conditions:

with iron(III) trifluoride;18-crown-6 ether in acetonitrile at 90; for 10 h;Autoclave;

Steps:

4 Example 4

In a 1 liter, 316 autoclave, first add 0.5 mol of ferric fluoride, 0.1 mol of 18-crown ether-6, and then pumpVacuum, pass anhydrous acetonitrile, and then quickly pass 1.05 mol of hexafluoropropylene and 1 mol of pentafluoropropionyl fluoride under stirring. After the completion of the reaction, keep the temperature at 90 ° C, the reaction time is 10 hours, and the reaction is over. Thereafter, it was cooled to 15 ° C, and allowed to stand for separation. The upper layer was an acetonitrile solvent in which a metal fluoride and a co-solvent were dissolved, and the lower layer was a colorless pentafluoroethyl perfluoroisopropyl ketone 314.4 g, and the purity was 98.7% (GC). Analytical), the yield of pentafluoroethyl perfluoroisopropyl ketone was 98.2%.
