Abstract: A method for removing unsaturated halogen impurities from 2,3,3,3-tetrafluoropropene (HFO-1234yf) of the type that may otherwise be difficult to separate from HFO-1234yf due to the impurities having boiling points which are close to that of HFO-1234yf and/or the potential of one or more of the impurities to form azeotropic mixtures with HFO-1234yf. A HFO-1234yf stream including unsaturated halogenated impurities is first passed through a caustic scrubber and is then passed through an acid scrubber. In the caustic scrubber and acidic scrubber, undesirable impurities are removed, in particular, 3,3,3-trifluoropropene (1243zf), 1-chloro-1-fluoroethylene (1131a), vinyl chloride (1140), and/or 1-chloro-2-fluoroethylene (1131).
