标 题:Vapor phase synthesis of hexafluoroisobutylene
发明人：BONFIELD JOHN H; ULMER HARRY E
权利人:ALLIED CORP
摘要:A vapor phase synthesis of hexafluoroisobutylene, which comprises contacting in the vapor phase in a catalyst zone, B, of a reactor hexafluoropropylene oxide with a fluorinated catalyst such as fluorinated silica-alumina at a temperature of about 400°-600° C. for a residence time sufficient to form a vapor stream comprising hexafluoroacetone which is thereafter directly contacted in a heating zone of the reactor with a vapor stream comprising a keytone-generating compound such as acetic anhydride at a temperature of about 500°-700° C. for a residence time sufficient to form a stream comprising hexafluoroisobutylene, substantially-free of perfluoroisobutylene and recovering the hexafluoroisobutylene product is disclosed. A direct one reactor vapor phase synthesis of hexafluoroisobutylene which comprises (a) contacting, in the vapor phase, hexafluoropropene with less than a stoichiometric amount of oxygen required to convert substantially all the hexafluoroisopropene into hexafluoropropylene oxide in the presence of a fluorinated catalyst such as fluorinated silica-alumina at a temperature of about 400°-600° C. for a time sufficient to form a vapor stream comprising hexafluoropropylene oxide substantially-free of oxygen; (b) directly contacting said vapor stream, in a catalyst zone, B, containing a fluorinated catalyst which is preferably the same as used in catalyst zone, A, at a temperature of about 400°-650°, preferably about 500°-650° C. for a time sufficient to form a vapor stream comprising hexafluoroacetone; (c) directly contacting the vapor stream comprising hexafluroacetone with a vaporized compound such as acetic anhydride at a temperature of about 500°-700° C., preferably about 600° C. for a time sufficient to form a vapor stream comprising hexafluoroisobutylene, substantially-free of perfluoroisobutylene; and (d) recovering hexafluoroisobutylene is also disclosed.

摘要:Disclosed is a process for the synthesis of 1,3,3,3-tetrafluoropropene which comprises, in one embodiment, reacting a compound of CF 3 X 1 with a compound of CX 2 Hâ•?CHX 3 , wherein X 1 , X 2 , and X 3 are each independently selected from the group consisting of fluorine, chlorine, bromine and iodine, to produce a reaction product comprising a compound of CF 3 CHâ•?CHX 3 , wherein X 3 is as described above; and when X 3 is not fluorine, fluorinating the compound to produce 1,3,3,3-tetrafluoropropene. The process in another embodiment comprises preparing tetrafluoropropene comprising thermally cracking one or more compounds capable of producing a reaction mixture which preferably comprises diflurocarbene radicals and vinylidene fluoride, and converting said reaction mixture into—tetrafluoropropene (1,3,3,3-tetrafluoropropene).
