    Abstract: The instant invention relates, at least in part, to a method increasing the cost efficiency for dehydrohalogenation production of a fluorinated olefin by recovering and recycling spent dehydrohalogenation agent. In one aspect, the present invention relates to dehydrohalogenating a fluorinated alkane (e.g. pentafluoropropane and/or hexafluoropropane) in the presence of a dehydrohalogenating agent to produce a fluorinated olefin (e.g. tetrafluoropropenes and/or pentafluoropropenes). Removal of spent dehydrohalogenating agent from the reactor allows for facile separation of organic and dehydrohalogenating agent, the latter of which is recycled.

    Abstract: This invention is directed to a method for mitigating HCl generation during 1230xa purification, which comprises the steps of; (a) adding a chelating agent into 1230xa crude, and (b) conducting the 1230xa purification in the presence of said chelating agent at a quantity sufficient to reduce or prevent 1230xa decomposition. Examples of chelating agent include tributyl phosphate (TBP), tripropyl phosphate (TPP), and triethyl phosphate (TEP). The concentration of chelating agent in 1230xa crude can range from 0.001 to 20 wt%, preferably from 0.01 to 10 wt%, and more preferably from 0.1 to 5 wt%.

    Abstract: The present invention relates, in part, to the discovery that the presence of moisture in 1,1,2,3-tetrachloropropene (HCO-1230xa) results in catalyst deactivation and accelerated corrosion in the reactor during the fluorination of HCO-1230xa to 2-chloro-3,3,3-trifluoropropene. By substantially removing the moisture, it is shown that the catalyst life is extended and results in improved operation efficiency of the fluorination reaction. Such steps similarly result in an overall improvement in the production of certain hydrofluoroolefins, particularly 2,3,3,3-tetrafluoropropene (HFO-1234yf).
