PROCESS FOR THE MANUFACTURE OF FLUORINATED OLEFINS

A method of converting a first reaction stream comprising at least one pentafluoropropene to a final product stream comprising at least one compound of formula (II): CHX=CZCF3 (II)wherein X and Z are each independently H or F, with the proviso that X and Z are not the same, comprising processing said first reaction stream under conditions effective to convert said at least one pentafluoropropene to at least one compound of formula (II);wherein said processing step comprises:(a) reacting said at least one pentafluoropropene to obtain a first product stream comprising at least one pentafluoropropane and at least one compound of formula (I): CH2XCHZCF3 (I)wherein X and Z are each independently H or F, with the proviso that X and Z are not the same;(b) separating said at least one compound of formula (I) from said first product stream to obtain a separated product stream and a second reaction stream, wherein said separated product stream comprises a higher weight percent of said at least one compound of formula (I) than said second reaction stream; and(c) reacting said second reaction stream under conditions effective to produce said at least one compound of formula (II).
