Z-1,1,1,4,4,4-헥사플루오로부트-2-엔을 생성하는 방법은 1,1,2,4,4-펜타클로로부타-1,3-다이엔을, 금속 할라이드를 포함하는 플루오르화 촉매의 존재 하에 증기상에서 플루오르화수소와 접촉시켜 E- 및 Z-1,1,1,4,4,4-헥사플루오로-2-클로로-2-부텐을 생성하는 단계를 포함한다. Z-1,1,1,4,4,4-헥사플루오로부트-2-엔을 생성하는 방법은 E- 및 Z-1,1,1,4,4,4-헥사플루오로-2-클로로-2-부텐을 염기와 접촉시켜 1,1,1,4,4,4-헥사플루오로-2-부틴을 생성하는 단계, 및 후속적으로 헥사플루오로-2-부틴을 수소화하여 Z-1,1,1,4,4,4-헥사플루오로-2-부텐을 생성하는 단계를 추가로 포함한다. A process for producing Z-1,1,1,4,4,4-hexafluorobut-2-ene comprises contacting 1,1,2,4,4-pentachlorobuta-1,3-diene with hydrogen fluoride in the vapor phase in the presence of a fluorination catalyst comprising a metal halide to produce E- and Z-1,1,1,4,4,4-hexafluoro-2-chloro-2-butene. A process for producing Z-1,1,1,4,4,4-hexafluorobut-2-ene further comprises contacting E- and Z-1,1,1,4,4,4-hexafluoro-2-chloro-2-butene with base to produce 1,1,1,4,4,4-hexafluoro-2-butyne, and subsequently hydrogenating hexafluoro-2-butyne to produce Z-1,1,1,4,4,4-hexafluoro-2-butene.
