METHOD FOR REMOVAL OF FLUORINATED ORGANICS FROM BYPRODUCT ANHYDROUS OR AQUEOUS HYDROCHLORIC ACID IN THE 1234YF VIA 1230XA PROCESS

Disclosed is a process to separate halogenated organic contaminants such as 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf), 2,3,3,3-tetrafluoropropene (HFO-1234yf), trifluoropropyne (TFPY) from hydrochloric acid (HCl) with an adsorbent selected from an activated carbon, an MFI molecular sieve, a carb...
