Process for the obtention of purified heptafluoropropane |
abstract |
Process for the obtention of HFC-227ea having a reduced content ofnorganic impurities, comprising at least subjecting a crude HFC-227ea tontwo distillation steps, consisting of a high pressure distillation stepnand a low pressure distillation step carried out at a pressure of at leastn1 bar lower than the high pressure distillation step. |
