Anhydrous AlCl3, or aluminum chloride, is a white to grayish-yellow crystalline solid that is a powerful Lewis acid catalyst. It’s highly reactive, especially with water, and is widely used in various chemical reactions, including Friedel-Crafts reactions, as a catalyst for polymerization, and in the production of dyes, fragrances, and polymers
Stability : As supplied it is stable at normal temperature & pressure.
Conditions to avoid : Avoid contact with bases, chlorides, sulphites,hypochlorite’s, sodium
hydroxide & potassium hydroxide.
Material to avoid : Long term contact with aluminum & alloys, zinc & alloys, carbon & steel
Reactivity:-
Air : No reaction
Water : Coagulates substances suspended or dispersed in water to settle quickly to form a filterable sludge.
Acids : With mineral acids bulk precipitation of solid occurs
Alkalis : Bulk precipitation with evolution of heat occurs
Hazardous Decomposition Products : Hydrogen chloride
