タイトルまたは説明

Name：aluminium sulfate；
Chemical formula：Al2(SO4)3；
Molecular weight:**2.*5ï¼›
Properties:White crystal, sweet;Industrial products are gray and white flaky,grainy or lump;Because of containing iron salt the color have light green;The surface is yellow because of the oxidation of low price iron salt.The crude products are grayish fine porous crystal structure;
Density:1.*9g/mL（*5℃）；
CAS：*********3；
EINECS:********0;
Solubility:Dissolve in water, insoluble in ethanol, etc;
Classification:Anhydrous and eighteen hydrates.Anhydrous material is a colorless trapezoid crystal.Dissolved in water, aqueous solution is acidic, slightly soluble in ethanol.The solubility in water increases with the rise of temperature.Eighteen hydrate (Al2 (SO4) 3. *8H2O) is a colorless monoclinic crystal,dissolve in water, insoluble in ethanol.The water solution is acidic by hydrolysis;
Chemical property:It is not easy to weathering and loses crystalline water. It is stable, heating will lose water, and high temperature will be broken down into oxide of alumina and sulfur.;
Application:
1. Paper industry: paper sizing agent;
2. Water treatment: coagulant;
3. Cosmetics: convergent;
4. Fire fighting industry: foam extinguishing agent composed of baking soda and foaming agent;
5. Fuel industry: precipitant;
6. Artificial gemstones and advanced ammonium alum: raw materials;
7. Albumin pasteurization: stabilizer;
8. Analysis reagent, mordant, tanning agent, bleaching agent, wood preservative, water purifying agent, precipitating agent, fixing agent, filler, etc.
