摘要：
A process for halogen exchange fluorination by contacting a halocarbon having a replaceable halogen other than fluorine with KF.nHF wherein n is 0.5-3 to provide a fluorinated hydrocarbon having at least one more fluorine than the starting halocarbon and, optionally, regenerating the KF.nHF with additional HF, or in a continuous process, with excess HF in the feed.
