Summary:The present invention relates to a process for making 2,3,3,3-tetrafluoropropylene and/or vinylidene fluoride. Disclosed is a process for the formation of a mixture of the compounds 2,3,3,3-tetrafluoropropene (1234yf) and vinylidine fluoride, comprising pyrolyzing 1,1,2-trifluoro-2-trifluoro-methyl-cyclobutaneunder conditions effective to produce a reaction product comprising 1234yf and vinylidinefluoride in a 1234yf: vinylidine fluoride molar ratio of from about 0.5 to about 1.2. 本发明涉及制备2,3,3,3-四氟丙烯和/或偏二氟乙烯的方法。本发明公开了形成化合物2,3,3,3-四氟丙烯(1234yf)和偏二氟乙烯的混合物的方法，所述方法包括在有效地产生包含其中1234yf：偏二氟乙烯摩尔比为约0.5-约1.2的1234yf和偏二氟乙烯的反应产物的条件下热解1,1,2-三氟-2-三氟甲基-环丁烷。
