Abstract

Composiciones azeotropicas y casi azeotropicas que comprenden 1,1,3,3,3-pentafluoropenteno (HFC-1225zc) y fluoruro de hidrogeno. Estas composiciones son de utilidad en procesos para producir y purificar HFC-1225zc. También se describen procesos que comprenden pirolisis de CF3CH2CF3 en CF3CH=CF2. También se describen en la presente procesos de elaboracion de HFC-1225zc que comprenden pirolisis de 1,1,1,3,3,3-hexafluoropropano (HFC-236fa) en ausencia de catalizadores de deshidrofluoracion en un reactor que presenta una zona de reaccion.
