Abstract
The present invention relates to a process for producing 2,3,3,3-tetrafluoropropene, comprising the steps of: a) providing a stream A comprising 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, bringing said stream A into contact with HF in the presence or absence of a fluorination catalyst in order to produce a stream B comprising 2,3,3,3-tetrafluoropropene; characterized in that the electrical conductivity of said stream A provided in step a) is less than 15 mS/cm.
