This product is a special structured gamma alumina produced through special processing techniques. It is non-toxic, odorless, odorless, and appears as white fine sand. It has high chemical purity, moderate adsorption performance, fast solution penetration rate, good decolorization effect, easy regeneration, long service life, and can be reused multiple times. It has strong water absorption in the air, remains unchanged after water absorption, and can be restored by drying at 110 ° C. It is insoluble in water and organic solvents, and soluble in strong acid and alkali solutions at high temperatures.
Purpose
This product is specially developed, researched, and produced as decolorizing and refining alumina for the production process of antibiotics. At present, it is mainly used in the production of cephalosporin sodium, cefotaxime sodium, cefoperazone, cefepime and other antibiotics, as well as decolorization and chromatography in the production process of traditional Chinese medicine flavonoids, Sanqi saponins, etc. in China.
In addition, it is widely used in other fine chemicals, pharmaceutical chromatography, chemical pharmaceuticals, and drying processes.
