Abstract
In this invention we are disclosing a process for the synthesis of hydrochlorofluoro olefins (HCFO) and/or hydrofluoroolefins (HFO). The process is based on the following steps of liquid phase, noncatalytic fluorination of hydrochloropropenes to form hydrochlorofluoropropenes and/or hydrofluoropropenes, followed by gas phase, catalytic fluorination of the hydrochlorofluoropropenes to form hydrofluoropropenes.
