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.
