Introduction
Benzoic Acid. The following is an introduction to the properties, uses, preparation, and safety information of benzoic acid:Properties:- Appearance: Benzoic acid is a white crystalline solid, soluble in water and organic solvents.- Chemical properties: Benzoic acid is acidic and can react with bases to form the corresponding salts.- Chemical structure: The benzoic acid molecule consists of a benzene ring with a carboxyl group (-COOH) attached to it.Uses:- Chemical synthesis: Benzoic acid is an important raw material for the synthesis of flavors, dyes, flexible polyurethane, and fluorescent substances.Preparation:- From benzene: Benzoic acid can be obtained by oxidizing benzene with oxygen in the presence of a catalyst.- From toluene: Benzoic acid can be obtained by oxidizing toluene with oxygen in the presence of a catalyst.Safety Information:- Benzoic acid is relatively safe for humans at room temperature, but the following precautions should still be observed:- Contact: Avoid direct contact with the skin and eyes. In case of contact, rinse immediately with plenty of water and seek medical attention promptly.- Inhalation: Avoid prolonged inhalation of benzoic acid vapors. Operate in well-ventilated areas.- Ingestion: Benzoic acid is somewhat toxic and must not be ingested.- Storage: Store benzoic acid away from fire and oxidizing agents to prevent combustion.
