Benzoic Acid CAS 65-85-0

Description

Benzoic Acid ：

Benzoic acid, also known as benzoic acid, has the molecular formula C6H5COOH. The simplest aromatic acid in which the carboxyl group is directly bonded to the benzene ring carbon atom is a compound in which a hydrogen on the benzene ring is substituted by a carboxyl group (-COOH). It is a colorless, odorless flake crystal. The melting point of 122.13 ° C, the boiling point of 249 ° C, the relative density of 1.2659 (15 / 4 ° C). It rapidly sublimes at 100 ° C, its vapor is very irritating, and it is easy to cause cough after inhalation. Slightly soluble in water, soluble in organic solvents such as ethanol, ether, chloroform, benzene, toluene, carbon disulfide, carbon tetrachloride and turpentine. Widely present in nature in the form of free acids, esters or derivatives thereof, for example, in the form of free acids and benzyl esters in benzoin; in free form in the leaves and bark of some plants; Essential oils are present in the form of methyl or benzyl esters; in horse urine, in the form of their derivatives, hippuric acid. Benzoic acid is a weak acid and stronger than fatty acids. Their chemical properties are similar, and they all form salts, esters, acid halides, amides, acid anhydrides, etc., which are not easily oxidized. An electrophilic substitution reaction can occur on the benzene ring of benzoic acid, and a meta-substitution is mainly obtained.
