Abstract:
The present invention discloses a manufacturing process to produce high purity 1234yf from 245eb, which preferably includes the removal of impurities present in 245eb raw material, the dehydrofluorination of 245eb, and the removal of impurities present in final crude product. The disclosed manufacturing process allows the production of a 1234yf product with lower the levels of 1225ye and/or trifluoropropene, preferably in amounts of less than about 500, and 50 ppm, respectively.
