Benzyl benzoate detection

Benzoic acid, also known as benzoic acid, with the molecular formula C6H5COOH, is a compound formed by the substitution of a hydrogen group (- COOH) on the benzene ring. At room temperature, it is a scale like or needle like crystal with a smell of benzene or formaldehyde. Its vapor is highly irritating and can cause coughing when inhaled. Slightly soluble in water, easily soluble in organic solvents such as ethanol and ether. Benzoic acid is a weak acid, stronger than fatty acids. They have similar chemical properties and can form salts, esters, acyl halides, amides, and anhydrides, all of which are not easily oxidized. Electrophilic substitution reactions can occur on the benzene ring of benzoic acid, mainly resulting in meta substituted products. Benzoic acid is widely present in nature in the form of free acids, esters, or their derivatives. Benzoic acid is commonly used as a drug or preservative, which has the effect of inhibiting the growth of fungi, bacteria, and molds. When used medicinally, it is usually applied to the skin to treat ringworm skin diseases. Used in the synthetic fiber, resin, coating, rubber, tobacco industry. Initially, benzoic acid was obtained by distillation of benzoin gum or hydrolysis in alkaline water, or by hydrolysis of hippuric acid. In industry, benzoic acid is produced by oxidizing toluene with air in the presence of catalysts such as cobalt and manganese; Or obtained by hydrolysis decarboxylation of phthalic anhydride. Benzoic acid and its sodium salts can be used as antibacterial agents for latex, toothpaste, jam, or other foods, as well as as as mordant agents for dyeing and printing
