Abstract

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