Aluminium Chloride Uses

 Aluminium Chloride  is probably the most commonly used Lewis acid and also one of the most powerful. It finds widespread application in the chemical industry as the classic catalyst for Friedel-Crafts reactions, both acylations and alkylations. The Friedel-Crafts reaction is the major use for aluminium chloride, for example in the preparation of anthraquinone (for the dyestuffs industry) from benz and phosgene. Aluminium Chloride also can be  used in polymerization and isomerization reactions of hydrocarbons. and used to introduce aldehyde groups onto aromatic rings,a wide variety of other applications in organic chemistry.

Aluminium Chloride Production

Anhydrous aluminum chloride is manufactured piimarily by the reaction of chlorine vapor on molten aluminum.
             2Al + 3Cl2 → 2AlCl3
In the process, chlorine is fed in below the surface of the aluminum, and the product sublimes and is collected by condensing. These air-cooled condensers are thin-walled, vertical steel cylinders with conical bottoms. Aluminum chloride crystals form on the condenser walls and are periodically removed, crushed, screened, and packaged in steel containers.

Aluminium Chloride Specification

 Aluminium Chloride (CAS NO.7446-70-0) is also named as AI3-01917 ; Alluminio(cloruro di) ; Alluminio(cloruro di) [Italian] ; Aluminium trichloride ; Aluminium, (chlorure d') ; Aluminium, (chlorure d') [French] ; Aluminiumchlorid ; Aluminiumchlorid [German] ; Aluminum chloride (1:3) ; Aluminum trichloride ; Aluminum, (chlorure d') ; Aluminum, (chlorure d')[French] ; CCRIS 6871 ; Caswell No. 029 ; Chlorure d'aluminium ; Chlorure d'aluminium [French] ; EPA Pesticide Chemical Code 013901 ; HSDB 607 ; NSC 143015 ; NSC 143016 ; Pearsall ; TK Flock ; Trichloroaluminum ; UNII-LIF1N9568Y . Aluminium Chloride (CAS NO.7446-70-0) is yellow to grey solid with a pungent odor. It is corrosive to tissue and toxic by ingestion. Contact with the skin or eyes in the presence of moisture causes thermal and acid burns. Aluminium Chloride behaves as an acidic salt. It can self-reactive. After long storage in closed containers, explosions often occur upon opening. Can cause ethylene(also other alkenes) to polymerize violently. Causes ethylene oxide to rearrange and polymerize, liberating heat. Can catalyze violent polymerization of allyl chloride. Addition to nitrobenzene containing about 5% phenol caused a violent explosion. Mixtures with nitromethane may explode when organic matter is present. Reacts violently with water if used in extinguishing adjacent fires.
