How is poly aluminum chloride made?

Answer 1

Aluminum chloride is desoleved in aluminum hydroxide aquas solution between 60 and 90 deg C some times a pressure of 2 to 3 bar is also applied in autoclave the reaction time is long almost 5 to 6 hours.

For raw materia of polyaluminium chloride,mainly AL(OH)3 ,HCL and Calcium aluminate powder.

They reaction together,then after being filtered to get the liquid.The PAC liquid can be dried with spray tower to get PAC solid.

Answer 2

Poly aluminum chloride (PAC) is typically produced by dissolving aluminum hydroxide in hydrochloric acid to form a solution, followed by polymerization of the solution through a controlled chemical reaction. The resulting product is then dried to form PAC powder or solution for various applications such as water treatment.
