Description

technical field [0001] The present disclosure relates to compositions comprising 2-chloro-1,1,1,2-tetrafluoropropane (HCFC-244bb) and at least one impurity. Such compositions can be used for various purposes, such as for the preparation of 2,3,3,3-tetrafluoropropene (HFO-1234yf or 1234yf) and similar compounds. Background technique [0002] Hydrofluoroolefins (HFOs) such as tetrafluoropropene are recognized as effective refrigerants, fire extinguishing agents, heat transfer media, propellants, blowing agents, blowing agents, gaseous dielectrics, disinfectant carriers, polymerization media, particulate removal fluids, Carrier fluids, polishing abrasives, displacement desiccants and power cycle working fluids. Due to the questionable environmental concerns associated with the use of some of these fluids, including the relatively high global warming potential associated with them, it is desirable to use fluids with the lowest possible global warming potential ( GWP) fluid.
