What is aluminum chloride?
Aluminum chloride, AlCl3, is well-known as a catalyst for organic reactions. This compound is soluble in water, hydrogen chloride, ethanol, chloroform, CCl4 and is slightly soluble in benzene. It is a silver-white powder but sometimes turns to yellow if it is contaminated by ferric chloride. It tends to absorb water easily (hygroscopic) to form monohydrate or hexahydrate. Aluminum chloride is a corrosive substance and it is also very toxic. It can cause high damage to the eyes, skin, and respiratory systems if inhaled or upon contact.
What is aluminum chloride made for?
Aluminum chloride is widely used for Friedel-Crafts reaction as a catalyst. AlCl3 works as an electron acceptor (Lewis Acid). AlCl3 is able to direct the reaction more efficiently and effectively. This catalyst is used to synthesize alkyl benzene from alkyl halide and benzene. It is also used for many industrial applications such as petrochemical manufacture, pharmaceuticals, dyes intermediates, and other organic chemicals. Moreover, it can be used for the metallurgical industry, cosmetics, antiperspirants, metallurgical industry, and lubricants.
Manufacturing Process:
There are mainly two ways of synthesis: manufacturing aluminium chloride with chlorine or hydrogen chloride, or obtaining aluminium chloride by extraction from raw materials. In the former method, aluminium chloride is widely manufactured by reacting with an aluminium metal with chlorine or hydrogen chloride. This reaction occurs at a temperature ranging from 650 to 750°C and is classified as an exothermic reaction. In the latter method, to produce aluminium chloride, the aluminium metals can be extracted from raw material, such as clay or fly ash.

The preferred method of preparing anhydrous aluminium chloride comprises the steps of:
- Alumina raw materials, such as clay, undergo the drying and calcining process to activate the alumina fraction for HCl leaching;
- Dissolving the alumina fraction into soluble aluminium chloride by HCl leaching of calcined clay.
- Solid/liquid separation to obtain remove all the solid that still contain in aluminium chloride solution, typically by the use of settlers and/or filters;
- Separation of any soluble iron chloride from process liquor;
- Crystallization of filtrate to separate slurry from aluminium chloride hexahydrate crystals;
- Heating the aluminium chloride hexahydrate crystals to a temperature up to about 450°C.
- Reducing aluminium chloride hexahydrate crystals to form anhydrous aluminium chloride.
Other ways of manufacturing aluminium chloride are:
Reaction of aluminum metal in a heated stream of hydrochloric acid gas
2 Al + 6 HCl → 2 AlCl3 + 3 H2
Reaction of bauxite with coke and chlorine at about 875°C
Catalytic chlorination of gamma-alumina in a fluidized bed
Poly aluminium chloride suppliers:
aluminum chloride can be purchased in bulk from Iran, Iran is one of the producers of this product in the region with different grades, medicine and industrial.
Poly aluminium chloride manufacturers and aluminium chloride manufacturers:
raw aluminum chloride also can be supplied from Iran but because of the low cost of production in Iran, its not recommended, so its better to buy the purified aluminium chloride instead of raw aluminium chloride.
Iran is one of the Poly aluminium chloride manufacturers and aluminium chloride manufacturer in the region.

what is poly aluminium chloride?
(PAC) Polyaluminum chloride is a polymer compound that is widely used in water and wastewater treatment (as a coagulant) and papermaking industries. This chemical product, also known as pack, has the chemical formula Al2Cl(OH)5 and has a very good performance in removing water turbidity. The pack is sold in drinking and sewage grades.
what is the chemical formula of poly aluminium chloride?
Poly Aluminum Chloride (Poly Aluminum Chloride) or hydrated aluminum chloride with the chemical formula AL2 (OH)n Cl6, is an inorganic (inorganic) polymer with strong coagulant properties and high efficiency, which is called PAC for short. Its monomer is a binuclear aluminum complex. This material benefits from high manufacturing technology and high quality raw materials and has been produced in recent decades. In fact, this newly arrived chemical substance is a suitable substitute for aluminum sulfate and chlorophyll as two old coagulants. Also, among its advantages, we can mention the high purity of the substance, molecular weight and high coagulation properties.

Is poly aluminium chloride toxic
Permanent neutralization of colloidal particles is the most important thing this coagulant does. As a result, they create suitable conditions for the chemical coagulation of particles, and this issue also causes the destabilization of colloidal particles. When suitable conditions are provided for the destabilization of suspended particles and when these substances are combined with each other, conditions for coagulation of particles and flocculation are also created. Finally, one can witness the passage of water through the sedimentation pond and the coagulation of solid particles that are separated from each other by sedimentation.
Understanding the Characteristics and Risks of Poly Aluminium Chloride in Water Treatment
The performance range of this substance is between 5 to 9 pH, and the most appropriate range of its performance is neutral pH between 6.5 to 7.6. This material also creates hydroxyl ions and anionic polymers, causing inorganic molecules and macromolecules to appear in water, which ultimately causes coagulation. When using this substance, a certain amount must be determined because otherwise it will cause the particles to become charged again and their instability, and in some cases it will also cause the formation of sludge. This case can be considered one of the main dangers of these substances.
Stabilization of colloidal particles is what this substance does first. That is, by sticking them together, it creates micro clots. This is where a coagulant agent such as polyelectrolytes, added to water, connects these small clots to each other and provides conditions for sedimentation. This substance must be fully understood before using it due to its special characteristics. In general, some points should be observed when using it because otherwise it will cause risks.
Although it does not pose serious risks, be careful not to touch yourself while using these substances. Contacting this substance will cause inflammation and irritation at the contact site, and it is better to follow safety precautions to prevent this. This is only one of the dangers that the use of this substance can lead to.
Apart from skin contact, contact with eyes and even breathing should be avoided. It is for these reasons that the use of safety equipment while working with this substance is considered a requirement. That is, use masks, glasses, gloves, hats and special clothes to avoid the dangers of this substance. This substance also causes corrosion in them if it comes into contact with any metal, and its other properties include being non-flammable. That is, it boils at a temperature between 100 and 120, but does not cause fire.
