Title
(EN) PROCESS FOR THE MANUFACTURE OF 1,1,1,2,3-PENTAFLUOROPROPANE
(FR) PROCEDE POUR LA FABRICATION DE 1,1,1,2,3-PENTAFLUOROPROPANE
Abstract
(EN)
A process is disclosed for producing CF3CHFCH2F using vapor phase catalytic dehydrohalogenation to produce CF3CF=CHF and HF, followed by vapor phase catalytic hydrogenation of CF3CF=CHF in the presence of HF.
(FR)
L'invention se rapporte à un procédé pour la production de CF3CHFCH2F en utilisant une déshydrohalogénation catalytique en phase vapeur pour produire CG3CF=CHF et HF, suivie par une hydrogénation catalytique en phase vapeur de CF3CF=CHF en présence de HF.
