Aluminium chloride, as one of the most commonly used and also one of the most powerful acid , finds a wide variety of applications in organic chemistry. It can be used to introduce aldehyde groups onto aromatic rings. This product is also finds application in the chemical industry as a catalyst for Friedel–Crafts reactions, both acylations and alkylations. For example in the preparation of anthraquinone (for the dyestuffs industry) from benzene and phosgene. It is also widely used for polymerization and isomerization reactions of hydrocarbons. Important examples include the manufacture of ethylbenzene, which used to make styrene and polystyrene, and also production of dodecylbenzene, which is used for making detergents.

Ereztech manufactures and sells this product in small and bulk volumes. Glass ampules, bottles or metal ampules or bubblers are available for packaging. For additional analytical information or details about purchasing Aluminium chloride contact us at
