Hexafluoro ring three phosphonitrile and the preparation method of 1 ethyoxyl 1,3,3,5,5 5 fluorine ring three phosphonitrile

The invention belongs to the preparation method technical field of phosphorus essence derivant, be specifically related to a kind of hexafluoro ring three phosphonitrile and the preparation method of 1 ethyoxyl 1,3,3,5,5 five fluorine ring three phosphonitrile.The preparation method of hexafluoro ring three phosphonitrile is to react with hexachlorocyclotriph,sphazene with pyridine hydrofluoride at low temperatures to obtain.The preparation method of 1 ethyoxyl 1,3,3,5,5 5 fluorine ring three phosphonitrile is by hexafluoro ring three phosphonitrile obtained and then reacts with ethylate and obtains product 1 ethyoxyl 1,3,3,5,5 5 fluorine ring three phosphonitrile.The method when per-fluorination step mild condition, be easily achieved, 1 ethyoxyl 1,3,3,5,5 five fluorine ring three phosphonitrile yield is high, is the preparation method of a kind of feasible industrialized production ethyoxyl five fluorine ring three phosphonitrile.
