    Abstract: The present invention provides a process for producing 2,3,3,3-tetrafluoropropene, comprising distilling a mixture of water and 2,3,3,3-tetrafluoropropene to separate the mixture into a first stream and a second stream, the first stream containing 2,3,3,3-tetrafluoropropene with a water content higher than the original mixture, and the second stream containing 2,3,3,3-tetrafluoropropene with a water content lower than the original mixture; and obtaining 2,3,3,3-tetrafluoropropene with a reduced water content from the second stream. The process of the invention can efficiently remove water from 2,3,3,3-tetrafluoropropene (HFO-1234yf).
