Paragraph 0037-0042; 0043; 0044; 0045, (2020/02/19)
PROBLEM TO BE SOLVED: To provide a method for producing a cyclic aryloxyphosphazene in a short time and in high yield under a mild condition by a simple operation. SOLUTION: Provided is a method for producing a cyclic aryloxyphosphazene represented by Formula (2), comprising reacting hexachlorocyclotriphosphazene with an aryl alcohol in a nitrile only or an organic solvent mixed with 40 vol.% or more and less than 100 vol.% of a nitrile in the presence of a pellet-like material of al least one hydroxide selected from the group consisting of potassium hydroxide and sodium hydroxide. [Ar is a substituted or unsubstituted aryl group.] SELECTED DRAWING: None COPYRIGHT: (C)2020,JPO&INPIT

A method of oligomerizing hexa(aryloxy)cyclotriphosphazatrienes to the corresponding oligomers is reported.The oligomerization has been carried out in the ion source of a mass spectrometer, at high vapour pressure of the trimers, and at a temperature of 200 deg C.The effects on the oligomerization reaction of experimental parameters, such as temperature, nucleophilicity, electrophilicity, and bulkiness of substituent groups on the trimers, and the presence of acidic species, have been investigated.High reaction temperatures inhibit the oligomerization reaction, leading to the formation of pyrolysis products.
