Recovery of hexafluoroacetone from a hexafluoroacetone-HF control

摘要

A process for recovery of hexafluoroacetone from the hexafluoroacetone-HF complex by contacting the complex with acetic anhydride under reaction conditions. The reaction produces liberated hexafluoroacetone and by-products, acetyl fluoride and acetic acid. The by-products can be further reacted in a cyclic process whereby acetic anhydride is regenerated for recycle.
