PRODUCTION OF FLUOROKETONE

摘要

PURPOSE:To obtain the title compound under low pressure in high yield, by using a mixture of a nonfluorine and aprotic polar solvent and a fluorine- containing solvent and reacting a fluorocarboxylic acid fluoride wit a fluoroolefin in the presence of a catalyst. CONSTITUTION:A fluorocarboxylic acid fluoride (e.g. perfluoropropionic acid fluoride) is reacted with a fluoroolefin (e.g. tetrafluoroethylene) in the presence of a catalyst by using a mixture of a nonfluorine and aprotic polar solvent such diglyme, acetonitrile or dimethylformamide and a fluorine-containing solvent such as perfluoroethane or tetrafluoroethylene as an inert solvent to give a fluoroketone (e.g. perfluorotriethylcarbinol). The reaction can be carried out under low pressure of about 3-15kg/cm<2> and a small amount of by-products is produced.
