UPRA CHEM Pvt. Ltd. has been established in the year 1985.


UPRA CHEM is involved in dealing of long list of chemicals for Industrial and Laboratory use.

The Company is also involved in chemical manufacturing activity, in a plot admeasures 3 acres, at Silvassa, since 1985.

It manufactures a chemical known as “Anhydrous Aluminium Chloride” (Alcl3) at a site situated in a backward area of Silvassa, Dadra & Nagar Haveli. This named place falls under Union Territory of India. The site is about 180 km. from Mumbai and can easily be reached by rail or road in about 3 hours. It is also very near to Industial Zones of Gujarat like Vapi (16 km), Ankleshwar(120 km), Vadodara(200km) and Ahmedabad (325 km) and can be reached by rail and road.

The plant was initially installed having manufacturing capacity of 5,000 tonnes per year.

Subsequently, in 1992, the production capacity was increased to 7,000 tonnes per year. 

The present capacity of teh plant is is 7,000 tonnes per year.

The main advantage in the manufacture of “Anhydrous Aluminium Chloride” is easy and abundant availability of all the raw materials within India. 

Uprachem is already serving its clients in UK, Gemany, Korea, France and many other countries across the globe.

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 .


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.


The product can be supplied in the following forms:

  • ground

  • sieved

Can be delivered as follows:

  • Silsack Bag with PVC Liner

  • MS Drums

  • Jumbo Bag General-purpose packaging 250 kg and 50 kg net weight.

Personal protection

Safety glasses, rubber gloves. Adequate ventilation.  


If anhydrous Aluminium Chloride comes in contact with the skin or clothing, do not
wash immediately with water. Severe burns can result from the great amounts of heat produced when anhydrous Aluminium Chloride is dissolved. Wipe off the excess Aluminium Chloride first with a cloth and then wash with large amounts of water.

If liquid Aluminium Chloride comes in contact with the skin or clothing, wash it off immediately and thoroughly with water.

In cases of splashes of liquid Aluminium Chloride in the eyes, flush immediately and thoroughly with large amounts of water and then rinse with a weak solution of sodium bicarbonate or boric acid. Consult a physician immediately.
