Aluminum Chloride vs Aluminum Chloride Hexahydrate
The difference between aluminum chloride and aluminum chloride hexahydrate
Aluminum Chloride (Aluminum Chloride) and aluminum chloride hexahydrate (Aluminum Chloride Hexahydrate), although the two have similar names, their properties are different.
Aluminum chloride, which is anhydrous, often in the form of white or slightly yellow crystalline powder. The texture is relatively pure and the chemical activity is quite high. In many organic synthesis reactions, it is often used as a catalyst because it can efficiently promote the reaction, such as the Friedel-Crafts reaction. Aluminum chloride can effectively catalyze the reaction of aromatic hydrocarbons with halogenated hydrocarbons or acyl halides, and help form carbon-carbon bonds. It is a great credit in the field of organic synthesis.
In contrast, aluminum chloride hexahydrate is a compound containing crystalline water. The appearance is mostly colorless and transparent or white and yellowish crystalline blocks. Its stability is higher than that of aluminum chloride, due to the presence of crystalline water, its chemical activity is alleviated to a certain extent. In the water treatment industry, aluminum chloride hexahydrate has excellent performance and is often used as a flocculant. It can be hydrolyzed in water to form a variety of hydroxyl aluminum ions, which can then be polymerized into large particles of flocculant, which can effectively absorb suspended impurities in water, clarify the water body, and ensure the cleanliness of the water.
The preparation methods of the two are also different. Aluminum chloride is mostly prepared by the direct reaction of metallic aluminum and chlorine gas. This process requires strict control of the reaction conditions to ensure the purity of the product. The preparation of aluminum chloride hexahydrate is often made from aluminum-containing minerals through multiple processes such as acid dissolution, impurity removal, and crystallization.
Users should be aware of the differences in characteristics between the two, and choose them carefully according to actual needs. If a high-activity catalyst is required, aluminum chloride is preferred; if it is used in scenarios where stability is required, such as water treatment, aluminum chloride hexahydrate is more suitable. In this way, we can make the best use of everything and achieve twice the result with half the effort.
