Title: METHOD FOR THE PRODUCTION OF BROMODIFLUOROMETHANE
Abstract:
A method for the production of bromodifluoromethane includes reacting hydrogen and dibromodifluoromethane at between about 400 °C and about 600 °C and separating the bromodifluoromethane from the reaction product. Contact times, pressure and molar ratios are not critical, although contact times of about 0.1 to about 20.0 seconds, and molar ratios of hydrogen to dibromodifluoromethane of about 0.1 to about 2.0, are preferred. The reaction occurs without catalyst, and high conversion, yield and selectivity are achieved.
