Claims
- 1. A process for the production of aminophenoxycyclotriphosphazene of the formula,
- N.sub.3 P.sub.3 (R.sub.1).sub.n (R.sub.2).sub.6-n
- wherein R.sub.1 is an aminophenoxy radical of the formula, ##STR3## and R.sub.2 has up to 6 carbon atoms and is an alkoxy, an alkenoxy, a fluoro-substituted alkoxy, a fluoro-substituted alkenoxy or an aryloxy radical of the formula, ##STR4## wherein each X is independently selected for each aminophenoxy radical from Cl, Br, F and H, each Y is independently selected for each aryloxy radical from Cl, Br, F and H, and wherein n is a whole integer which is .gtoreq.1 and .ltoreq.6 said process comprising, reacting a chlorocyclotriphosphazene and an R.sub.1 salt to form an R.sub.1 -chlorocyclotriphosphazene having n R.sub.1 substituents and 6-n chloride constituents and then reacting the R.sub.1 -chlorocyclotriphosphazene and an R.sub.2 salt for a time period sufficient to yield said aminophenoxycyclotriphosphazene, said reactions in both steps occurring in an inert, organic solvent medium, at a temperature within the range of from about 20.degree. C. to about 150.degree. C., and with a molar ratio of said R.sub.1 -chlorocyclotriphosphazene to the R.sub.2 anion component of said R.sub.2 salt of 1:b wherein b>5-n.
- 2. The process of claim 1 wherein said R.sub.2 salt is an alkali metal salt.
- 3. The process of claim 1 wherein said R.sub.2 salt is a sodium salt.
- 4. The process of claim 1 wherein R.sub.2 is phenoxide.
- 5. The process of claim 1 wherein R.sub.2 is isopropoxide.
- 6. The process of claim 1 wherein R.sub.2 is 2,2,2-trifluoroethoxide.
- 7. The process of claim 1 wherein R.sub.2 is 2,2,3,3,4,4,4-heptafluorobutoxide.
- 8. The process of claim 1 wherein said temperature is within the range of from about 50.degree. C. to about 140.degree. C.
- 9. The process of claim 1 wherein n is 2 or 3.
- 10. The process of claim 1 wherein b.gtoreq.6-n.
- 11. The process of claim 1 wherein R.sub.2 is an aryloxy radical.
