Anhydrous Aluminium Chloride:

Anhydrous Aluminium Chloride is a versatile Inorganic Chemical and finds application in a large number of Organic and Inorganic Chemical Syntheses and Reactions.

It is mainly used as Catalyst for the Chemical, Petrochemical and Pharmaceutical industries as also an auxiliary in the production of dyes and in the paper and textile industries.

Application

In the chemical, petrochemical and pharmaceutical industries: 

As a catalyst or as a component of catalyst systems for a number of chemical reactions, examples of which are as follows: 

Reactions of aromatic hydrocarbons with alkyl halides and other halocarbons, alkenes, primary and secondary alcohols, various alkanes, carbonyl halides and anhydrides, carbon monoxide and hydrogen chloride, epoxides, unsaturated amines. 

Reactions between unsaturated compounds, e.g. alkenes with hydrogen sulphide, isoalkanes, alkyl halides, acid chlorides, and (methyl) acrylates, butadiene and butadiene derivatives with formaldehyde, alpha, beta-unsaturated carbonyl compounds with vinyl ethers, alpha, beta-unsaturated aldehydes with alcohols or acetic acid. 

The isomerization of alkanes and alkenes, alkyl-substituted aromatic compounds, alkyl and aryl halides. 

Disproportion and transalkylation of alkyl-substituted aromatic hydrocarbons. 

Disproportion of halocarbons. 

Dimerization and polymerization of alkenes. 

Chlorination of chloroalkanes, chloroalkenes, and other aliphatic or aromatic compounds. 

Additive in the production of titanium dioxide pigments from titanium tetrachloride. 

Raw material for the production of special aluminium oxides . 

Auxiliary in the synthesis of dyes . 

The paper industry uses it in the production of parchment ; and the textile industry for carbonizing wool . 


Storage 

Aluminium chloride anhydrous must be stored in a cool, dry place. Before the drums are opened, they must be aired through the lids and tightly closed again. Unopened, original containers may be stored for 12 months. If the storage period is longer, caking can be expected. 

Leakages of the bundles cause an increase of pressure by reaction of aluminium chloride with air humidity to toxic and corrosive hydrogen chloride. Therefore the bundles have to be controlled in regular intervals, formed positive pressure that has to be discharged by careful opening of the vent screw. During this operation the personal protection equipment, especially respiratory protection, is to be used (for further information, please have a look to the safety data sheet). 

Aluminium chloride does not burn, but it should not be stored together with combustible materials, so that the possibility of a reaction between water and aluminium chloride is excluded when extinguishing a fire. 

Packaging/Delivery
