PCT No. PCT/EP90/01055 Sec. 371 Date Feb. 24, 1992 Sec. 102(e) Date Feb. 24, 1992 PCT Filed Jul. 2, 1990 PCT Pub. No. WO91/00279 PCT Pub. Date Jan. 10, 1991.A process for the preparation of 2,4,6-trifluoro-1,3,5-triazine (cyanuric fluoride) in high purity and high yield at relatively low temperatures by reacting 2,4,6-trichloro-1,3,5-triazine (cyanuric fluoride [sic]) or mixed chlorinated/fluorinated 1,3,5-triazines with at least the equivalent amount of sodium fluoride, potassium fluoride or cesium fluoride or any desired mixture of these alkali metal fluorides in a dipolar aprotic solvent at temperatures from about 30 DEG C. to about 110 DEG C. and isolating the 2,4,6-trifluoro-1,3,5-triazine formed by distillation.
