Description

Aluminium Chloride Solution CAS NO 7371-55-3 is an aqueous solution of aluminium chloride, a versatile inorganic chemical widely used as a Lewis acid catalyst and reagent. Its primary value lies in its potent catalytic activity and high reactivity, which are essential for driving key industrial chemical transformations. This solution is a critical raw material for manufacturers in the pharmaceutical, fine chemical, and water treatment industries, where consistent quality and reliable supply are paramount for process efficiency.

Application

• Catalyst in Organic Synthesis: Widely employed as a Lewis acid catalyst in Friedel-Crafts alkylation and acylation reactions, as well as in polymerization processes.
• Pharmaceutical Intermediate Production: Used in the synthesis of active pharmaceutical ingredients (APIs) and other complex organic molecules.
• Water & Wastewater Treatment: Acts as a highly effective coagulant and flocculant for the removal of suspended solids, phosphates, and other contaminants.
• Dye & Pigment Manufacturing: Serves as a mordant in dyeing processes and as a raw material in the production of certain inorganic pigments.
• Petroleum Refining: Utilized in alkylation processes within refineries to produce high-octane gasoline components.
• Production of Aluminium Compounds: A key precursor in the manufacture of various aluminium salts and hydroxides.
• Adhesive & Sealant Formulation: Incorporated as a cross-linking agent or curing agent in specific industrial adhesive systems.
