Abstract (en)
[origin: WO2019170989A1] The invention relates to a process for producing 2,3,3,3-tetrafluoropropene, comprising the steps of: a) supplying a stream A containing at least one of the compounds selected from the group consisting of 2-chloro-3,3,3-trifluoropropene and 2,3-dichloro-1,1,1-trifluoropropane; b) in a reactor, contacting said stream A with HF, optionally in the presence of a fluorination catalyst, to produce a stream B containing 2,3,3,3-tetrafluoropropene; characterised in that the electrical conductivity of said stream A supplied at step a) is lower than 15 mS/cm.
