1．氟化钾 Potassium Fluoride (high active anhydrous potassium fluoride)
该产品主要性状为纯白色细粉，粒度为300目的空心球状物，熔点为859.9℃，沸点为1505℃。 主要规格为：含水量低于0.3％，氯化物低于0.2个百分点，(以CL计)游离酸和游离碱分别低于0.1%和0.05％。同时，该产品具有高度的稳定性及广泛的用途，普遍应用于医药、农药等行业，其卓越的性能表现在有机氟化反应中的高活性、高收率、低用量、低副产。其次，在进行氟化反应时，不必使用价格昂贵的相转移法催化剂。另外，由于该产品在密封条件下，可长期保持超细粉状态，不结块，不吸潮，使用前出不需进行二次加工，从而简化了工艺，节约了能源，降低了劳动强度，防止了环境的污染。

As the development of new pharmaceuticals, pesticides and dye stufts, of 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 is 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 labour strength is reduced, environment is protected and energy saved.
