Synthetic Route of 1835-65-0,Some common heterocyclic compound, 1835-65-0, name is 3,4,5,6-Tetrafluorophthalonitrile, molecular formula is C8F4N2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
One hundred (100) g of the benzonitrile solution as the mother liquor obtained in Example 8 and 80 g of an aqueous 70percent sulfuric acid solution added thereto were stirred together at room temperature for 2 hours. Then, the resultant reaction solution was left standing at rest and allowed to separate into an organic layer (benzonitrile solution layer) and a water layer. When the organic layer was analyzed, it was found to contain absolutely no benzoic acid fluoride.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3,4,5,6-Tetrafluorophthalonitrile, its application will become more common.
