METHOD OF MAKING FLUORINATED PROPANES

摘要

The invention provides a process for the manufacture of fluoropropianes, and more particularly, the manufacture of 1, 1, 1,3,3,3 -hexafluoropropane (HFC23 6fa) and 1, 1, 1,2,3,3,3 -heptafluoropropane (HFC-22,7ea). The process utilizes 3­carbon by-products, i.e. waste material from other commercial processes as raw material. The process also avoids the use of hexafluoropropane (HFP) as a reactant for making HFC-227ea, and is able to convert any three-carbon hydrocarbon (HQ, hydrochlorofluorocarbon (HCFC), chlorofluorocarbon (CFC) compound or any halogenated propanes and produce high valued three-carbon hydrofluoroicarbons (HFCs) at significantly lower cost than current commercial processes.
