Catalytic isomerization of Z-1,1,1,4,4,4-hexafluoro-2-butene to E-1,1,1,4,4,4-hexafluoro-2-butene

Abstract:

A process is disclosed for (i) producing E-1,1,1,4,4,4-hexafluoro-2-butene (E-HFO-1336mzz) from Z-1,1,1,4,4,4-hexafluoro-2-butene (Z-HFO-1336mzz), comprising the steps of (a) providing a starting material comprising Z-1,1,1,4,4,4-hexafluoro-2-butene, (b) contacting the starting material with a suitable catalyst in a reaction zone to produce E-HFO-1336mzz; and optionally, (c) recovering the E-HFO-1336mzz. The process may be performed in the gas phase or in the liquid phase and as a batch process or as a continuous process.
