Abstract:
A method for forming 2,3,3,3-tetrafluoropropene (HFO-1234yf) comprising providing a dehydrochlorination starting material having relatively low concentrations of 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf), especially and preferable less than about 8.0% when the dehydrochlorination reaction utilizes no substantial amount of catalyst or catalyst comprising austenitic nickel-based materials.
