Description

white crystalline powder and chunks

Aluminium sulfate octadecahydrate is a hydrate resulting from the the formal combination of anhydrous aluminium sulfate with approximately 18 mol eq. of water. The commercial product usually contains 5-10% less water than theory. It is one of the commonest hydrates of aluminium sulfate. It is a hydrate and an aluminium sulfate. It contains an aluminium sulfate (anhydrous).

Aluminum sulfate octadecahydrate Use and Manufacturing

Methods of Manufacturing

Sulfuric acid reacts with high-quality low-iron aluminum hydroxide. The reaction liquid is settled, the clear liquid is neutralized by adding sulfuric acid to neutral or slightly alkaline, and then concentrated to about 115°C, cooled, solidified, and crushed to obtain a finished product. 2AI(OH)3+3H2SO4→Al2(SO4)3+6H2O

Uses

It is used to formulate aluminum tanning agent, tanned fur and white leather, or used for combined tanning. The dosage is 3.3%～3.96%.
