    Abstract: The present invention is directed towards a method of purification of chloroolefins having 3 carbons and to a method to provide stable compositions of chloroolefins having 3 carbons. The chloroolefins are purified via the use of a solid adsorbents for the removal of decomposition product such as phosgene and/or phosgene precursory from the reaction of the chloroolefins with oxygen. The chloroolefins stabilized against an increase of the phosgene level via the addition of inhibitors to the chloroolefins.

    Abstract: A one reactor, gas phase catalyzed process for the fluorination of 1,1,2,3-tetrachloropropene (1230xa) to produce 1,1,1,2-tetrafluoropropene (1234yf) is disclosed. The process of the present invention is a catalytic, gas phase fluorination using a high pressure activated catalyst which is supported or unsupported. Fluorination products of the formula CF3R, where R is selected from -CCl=CH2, -CF=CH2, -CF2-CH3, -CFCl-CH3 and mixtures thereof are produced. Co-produced materials are separated from the desired product and recycled to the same reactor.
