Molecular weight :474.39
Molecular formula/chemical symbol :AIK(SO4)2.12H2O
Description :
Colorless crystal or powder, odorless, slightly sweet and astringent taste, and convergence. Weathering in dry air, lose crystal water, melting in the humid air Tangshui. Soluble in glycerol, soluble in water, aqueous acidic reaction, hydrolysis gelatinous precipitate of aluminum hydroxide. Insoluble in alcohol and acetone.The 60 ~ 65 ℃ sulfuric acid drying lost 9 of molecular water, completely lost in the the twelve crystal water at 200 ℃, higher temperature decomposition of sulfur trioxide.
USES :
Used as a water purification agent, paper sizing agents, dyeing mordant, retarding agent, pharmaceutical preservatives, astringents and topical hemostatic agents, and photo developing process fixer hardener. It also can be used for livestock mixed with feed to prevent diseases such as.
