Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 696-82-2, name is 2,4,6-Trifluoropyrimidine. This compound has unique chemical properties. The synthetic route is as follows.
(According to the process of prior German Patent Application P 39 00 471 (O.Z. 0050/40474)) At -20 C. and over a period of 45 minutes, 335.8 g (1.865 mol) of 30% strength sodium methylate (in methanol) was added to a mixture of 250 g (1.865 mol) of 2,4,6-trifluoropyrimidine, and the mixture was stirred for a further 30 minutes at this temperature. The temperature was then allowed to rise to 25 C., and the reaction mixture was evaporated down to about one fifth of its volume. The mixture obtained was partitioned between diethyl ether and water, after which the organic phase was dried over magnesium sulfate and evaporated down. Distillation (1.1 meter column, 3 mm V-shaped packings) gave 141.6 g (52% of theory) of the title compound of boiling point 144-145 C. Distillation of the residue through a fractionating column (from Normag) gave 114.4 g (42% of theory) of 4,6-difluoro-2-methoxypyrimidine of boiling point 157-161 C.
According to the analysis of related databases, 696-82-2, the application of this compound in the production field has become more and more popular.
