Claims15
A process of synthesizing bromotrifluoropropenes, the process comprising the steps of:
- mixing 3,3,3-trifluoropropyne with hydrogen bromide to make a first mixture;
- and, contacting the first mixture with a catalyst at a temperature of at least 50° C. to yield at least one bromotrifluoropropene.
A process of synthesizing bromotrifluoropropenes, the process comprising reacting 3,3,3-trifluoropropyne with hydrogen bromide without a catalyst at a temperature of at least 50° C. to yield at least one bromotrifluoropropene.
