Aluminum acetate (Aluminum Acetate), its chemical formula is usually written $Al (CH_3COO) _3 $.

Aluminum acetate is widely used in the pharmaceutical, printing and dyeing industries. In the pharmaceutical field, it is often used as an astringent agent. In dermatology external drugs, it can help the skin converge, reduce inflammation, slow down skin exudation, and has a therapeutic effect on eczema, dermatitis and other diseases. In the printing and dyeing industry, it acts as a mordant. By virtue of the chemical interaction with dyes and fabrics, it enhances the adhesion fastness of dyes to fabrics, making dyeing more uniform and durable.

The common method for preparing aluminum acetate is to react with acetic acid with aluminum hydroxide. During this reaction process, aluminum hydroxide is gradually dissolved in acetic acid, and chemically reacts to form aluminum acetate and water. The reaction equation is as follows: $Al (OH) _3 + 3CH_3COOH = Al (CH_3COO) _3 + 3H_2O $.

When using aluminum acetate, safety matters should be kept in mind. It is irritating to a certain extent. During operation, if you accidentally contact the skin or eyes, you should immediately rinse with plenty of water. If the situation is serious, you need to seek medical attention immediately. For storage, it should be placed in a cool, dry place, away from fire sources and oxidants to prevent danger.
