How is aluminum trihydrate (CAS: 1302-74-5) typically synthesized?

Aluminum trihydrate is typically synthesized by the hydrolysis of aluminum salts in an alkaline medium. Common methods include the use of aluminum sulfate and an excess of sodium hydroxide. The process involves the gradual addition of the base to the salt solution, leading to the formation of the hydrate as a precipitate. The product is then usually dried and calcined to remove water from the structure, yielding aluminum oxide. The synthesis is influenced by reaction conditions such as pH, temperature, and the concentration of reactants.
