The invention provides a process for the manufacture of fluoropropanes, and more particularly, the manufacture of 1,1,1,3,3,3-hexafluoropropane (HFC-236fa) and 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea). The process utilizes 3-carbon 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 (HC), hydrochlorofluorocarbon (HCFC), chlorofluorocarbon (CFC) compound or any halogenated propanes and produce high valued three-carbon hydrofluorocarbons (HFCs) at significantly lower cost than current commercial processes.
本发明提供了一种用于制造
氟丙烷的工艺,更具体地说,是制造
1,1,1,3,3,3-六氟丙烷(HFC-236fa)和1,1,1,2,3,3,3-
七氟丙烷(HFC-227ea)。该工艺利用其他商业过程的3碳副产品,即废料,作为原料。该工艺还避免使用
六氟丙烷(
HFP)作为制造HFC-227ea的反应物,并能将任何三碳烃(HC)、
氯氟烃(HCFC)、
氯氟碳化合物(CFC)或任何卤代
丙烷转化为高价值的三碳氢
氟烃(HFC),成本显著低于目前的商业过程。
