1. Solvent characteristics


Aluminum chloride can dissolve various inorganic and organic compounds, making it of great value as a solvent in chemical synthesis and material preparation. In certain specific chemical reactions, aluminum chloride not only acts as a solvent, but also affects the reaction process and product selectivity through its acidic properties.


1.1 Organic synthesis


In organic synthesis, aluminum chloride is often used to promote certain types of reactions, such as Friedel Crafts reactions. In these reactions, aluminum chloride not only serves as a solvent, but also as a catalyst to increase the reaction rate by activating the reactants.


1.2 Metal dissolution


Aluminum chloride, as a solvent, can dissolve various metals, which is particularly important in metal smelting and recovery processes. For example, in the production process of aluminum, aluminum chloride acts as a solvent to participate in the dissolution of bauxite and the extraction of aluminum.


2. Electrolyte characteristics


The electrolyte properties of aluminum chloride are equally important in its industrial applications. In the electrochemical process, aluminum chloride provides chloride ions, which act as charge carriers and are crucial for the electrochemical reaction.


2.1 Production of Aluminum


Aluminum chloride plays a core role as a molten salt electrolyte in the production of aluminum. In the Hall Heriot electrolysis process, aluminum oxide is dissolved in a molten mixture of aluminum chloride and other chlorides, producing metallic aluminum and chlorine gas through electrolysis.


2.2 Electroplating


Aluminum chloride is also used in the electroplating process as an electrolyte to participate in metal deposition. In some electroplating processes, aluminum chloride provides the necessary chloride ions to help form a uniform and strong adhesion metal coating.


3. Polymerization reaction


Aluminum chloride acts as a catalyst in polymerization reactions, promoting the activation and polymerization of monomers. In hydrocarbon polymerization reactions, aluminum chloride helps to synthesize specific types of polymers, such as polystyrene and ethylbenzene.


4. Environmental and safety considerations


The use of aluminum chloride needs to consider its potential impact on the environment and operational safety. Aluminum chloride is corrosive and may cause damage to human health and equipment. Therefore, appropriate safety measures must be taken during the use of aluminum chloride, such as wearing protective clothing, eye masks, and gloves.


5. Green chemistry and alternatives


With increasing attention to environmental sustainability, the chemical industry is seeking more environmentally friendly alternatives to reduce the use of aluminum chloride. For example, developing new catalysts and solvents to reduce the dependence of aluminum chloride in certain applications.




Aluminum chloride, as a multifunctional inorganic compound, is widely used in solvents and electrolytes. It plays an important role in chemical synthesis, metal smelting, electroplating, and polymerization reactions. However, the use of aluminum chloride also brings environmental and safety challenges. Therefore, the chemical industry needs to continue exploring safer and more environmentally friendly alternatives to achieve sustainable development. Nevertheless, aluminum chloride is still one of the indispensable chemicals in many industrial processes.
