Ⅰ APPLICATIONS
As the development of new pharmaceuticals, pesticides and dye stuffs, some of which contain fluorine, high active anhydrous potassium fluoride is becoming more and more important. The fact that the quality of the product is better than all the same kind of products proved by the authoritative examination and customers. Compared with normal potassium fluoride, high active anhydrous potassium fluoride is characterized by high activity, high yield, low consumption and low by-product in organic fluoridation. With this product, phase transfer catalysts can not be used in fluoridation. The fine powder of the product can be kept if it is sealed well. This new production process is not only easily controlled, but also the labor strength is reduced, environment is protected and energy saved.
