| abstract | A composition comprising 3,3,3-trifluoro-2-chloro-prop-1-ene (CF3CCl=CH2, 1233xf) and 1233xf oligomers in an amount less than about 0.5wt%. The reduced oligomer content prevents blocking of equipment and fluorination catalysts used in the formation of hydrofluoroolefins (HFOs). The composition may comprise a polymerisation inhibitor. The reduction in oligomer concentration may be produced by the purification of 3,3,3-trifluoro-2-chloro-prop-1-ene (1233xf), preferably by distillation. A fluorination process is also disclosed, the process comprising the steps of providing said composition and then contacting the composition with a fluorinating agent in the presence of a catalyst to produce a fluorination product stream. Preferably the fluorinating agent is hydrogen fluoride (HF). The fluorination product stream may comprise HF, HCl and a compound having the formula CF3CFXCH3 wherein X is F or Cl. The product stream may also comprise 2,3,3,3-tetrafluoropropene (CF3CF=CH2, 1234yf). Preferably the fluorination reaction is carried out in the vapour phase. The process may also comprise the step of converting the compound having the formula CF3CFXCH3 to 2,3,3,3-tetrafluoropropene (CF3CF=CH2, 1234yf). Also claimed is a process for preparing 2,3,3,3-tetrafluoropropene (CF3CF=CH2, 1234yf) comprising the step of fluorination of said composition comprising 3,3,3-trifluoro-2-chloro-prop-1-ene (CF3CCl=CH2, 1233xf) and 1233xf oligomers in an amount less than about 0.5wt%. |
