Patent ID: 8067649

Claim:
A process for producing fluorinated organic compounds comprising: (a) fluorinating in a first fluorination step at least one compound of Formula (I): CHX═CClC(X) 3 (I) with a first fluorinating agent in a first reactor to produce at least one compound of Formula (IA): CHX═CClCF 3 (IA) where each X is independently H or Cl; (b) fluorinating in a second fluorination step said at least one compound of Formula (IA) in a second reactor to produce at least one compound of Formula (IB): CH 2 XCClFCF 3 (IB) with a second fluorinating agent; (c) recycling at least a portion of said at least one compound of Formula (IB) back to said first reactor as a recycled compound of Formula (IB); and (d) dehydrochlorinating said recycled compound of Formula (IB) in said first reactor to produce at least one compound of Formula (II): CF 3 CF═CHZ (II) where Z is independently H or Cl.
