Abstract
(DE)
Verfahren zur Herstellung von 2,4,6-Trifluor-1,3,5-triazin (Cyanurfluorid) in hoher Reinheit und hoher Ausbeute bei relativ niederen Temperaturen, indem man 2,4,6-Trichlor-1,3,5-triazin (Cyanurchlorid) bzw. gemischtchlorierte-fluorierte 1,3,5-Triazine mit der mindestens äquivalenten Menge Natrium-, Kalium- oder Cäsiumfluorid oder eines beliebigen Gemisches dieser Alkalimetallfluoride in einem dipolar aprotischen Lösungsmittel bei Temperaturen von etwa 30°C bis etwa 110°C umsetzt und das gebildete 2,4,6-Trifluor-1,3,5-triazin durch Destillation isoliert.
(EN)
The invention concerns a method of preparing high yields of high-purity 2,4,6-trifluoro-1,3,5-triazine (cyanuric fluoride) at relatively low temperatures by reacting 2,4,6-trichloro-1,3,5-triazine (cyanuric chloride) or mixed chlorinated/fluorinated 1,3,5-triazines with an at least equivalent amount of sodium, potassium or caesium fluoride, or any mixture of these alkali metal fluorides, in a polar aprotic solvent at a temperature between about 30°C and about 110°C, and isolating by distillation the 2,4,6-trifluoro-1,3,5-triazine thus formed.
(FR)
Selon un procédé de production de grandes quantités de 2,4,6-trifluoro-1,3,5-triazine (fluorure de cyanure) très pure à des températures relativement basses, on convertit de la 2,4,6-trichloro-1,3,5-triazine (chlorure de cyanure) ou de la 1,3,5-triazine mi-chlorée mi-fluorée avec une quantité au moins équivalente de fluorure de sodium, de potassium ou de césium ou d'un mélange de ces fluorures de métaux alcalins, dans un solvant aprotique dipolaire à des températures comprises entre 30°C et 110°C environ, puis on isole par distillation la 2,4,6-trifluoro-1,3,5-triazine ainsi obtenue.
