Abstract

The present invention relates in part to the discovery that the presence of impurities in a reactor for dehydrochlorinating HCFC 244bb to HFO 1234yf results in selectivity changeover from HFO 1234yf to HCFO 1233xf. By substantially removing such impurities it is shown that the selectivity to HFO 1234yf via dehydrochlorination of HCFC 244bb is improved.
