Abstract: A method of chlorinating a antimony fluorohalide catalyst is disclosed. In one embodiment the method comprises contacting an antimony fluorohalide catalyst that contains one or more fluorines with a regenerating agent chosen from 2-chloro-3,3,3-trifluoropropene (1233xf), 1,1,1,3-tetrachloropropane (250fb), 2-chloro-1,1,1,2-tetrafluoropropane (HCFC-244bb) and combinations of 1233xf, 250fb, and 244bb, under conditions effective to exchange at least one fluorine in the antimony fluorohalide catalyst with chlorine. The method can be used to regenerate spent antimony fluorohalide catalyst, for example regenerating SbCl5 from SbF5.

Abstract: A method of utilizing a catalyst for the sterilization, disinfection and purification of indoor air. The catalyst carrier is made of inorganic porous material such as Silica, Zeolite, Diatomite, Sepiolite, Montmoroillonite, and Aluminum oxide. The catalyst carrier can also be made of Cordierite, or Mullite ceramic honeycomb. After dipping into stabilized sodium hypochlorite solution or stabilized chlorine dioxide solution, the catalyst is produced after dehydration. The catalyst is irradiated with ultraviolet lamp to generate gas-phase free radicals including reactive particles such as .OH, .ClO2, .HO2, .O, thereby sterilizing microbial air pollutants such as viruses, bacteria, fungi and other microorganisms, and remove chemical air pollutants such as formaldehyde.

Abstract: The present invention relates, in part, to the discovery that the presence of HF in a HCFC-244bb feedstream in a reaction for the preparation of HFO-1234yf results in selectivity changeover from HFO-1234yf to HCFO-1233xf. By substantially removing HF, it is shown that the selectivity to HFO-1234yf via dehydrochlorination of HCFC-244bb is improved.
