trichloroalumane,hydrate - Introduction
Aluminum chloride hydrate refers to a compound formed by an aluminum ion and a chloride ion forming a coordinate bond and combining with a water molecule. Its chemical formula is AlCl3 · nH2O, where n represents the degree of hydration.
Aluminum chloride hydrate is colorless crystalline or white granular solid. It has strong hygroscopicity, can absorb a large amount of water and form hydrates. When exposed to air, it gradually decomposes to form hydrogen chloride gas.
Aluminum chloride hydrate is widely used in the chemical industry. It is often used as a catalyst, especially in organic synthesis reactions, such as the alkylation of aromatic hydrocarbons, the preparation of hydrofluoric acid, etc. In addition, it can also be used for metal surface treatment, preparation of aluminum metal, etc.
The preparation of aluminum chloride hydrate can be obtained by reacting anhydrous aluminum chloride with water. Under normal circumstances, we can slowly add anhydrous aluminum chloride powder to water and heat and stir until the reaction is complete.
Pay attention to safety when using aluminum chloride hydrate. It is irritating and corrosive and should avoid contact with skin, eyes, etc. Personal protective equipment such as lab gloves and safety glasses should be worn during operation. At the same time, avoid contact with combustibles to prevent fire or explosion. In storage should be sealed to avoid contact with moisture in the air. If ingested or inhaled, seek medical attention immediately.
