Benzoic acid, furthermore referred to as benzoic acid, has a molecular formula of C6H5COOH. It is one of one of the most convenient fragrant acid in which the carboxyl team is directly attached to the carbon atom of the benzene ring. It is a substance developed by transforming a hydrogen on the benzene ring with a carboxyl team (-COOH). It is an anemic, smell definitely cost-free half-cracked crystal. The melting point is 122.13 ° C, the boiling point is 249 ° C, in addition to the family member thickness is 1.2659 (15/4 ° C). It sublimates quickly at 100 ° C, as well as its vapor is incredibly irritating, which can promptly cause coughing after breathing. A little soluble in water, rapidly soluble in natural solvents such as ethanol, ether, chloroform, benzene, toluene, carbon disulfide, carbon tetrachloride in addition to turpentine.It exists completely in nature in the form of absolutely cost-free acid, ester or its byproducts, as an example, Benzoic Acid Option exists in the form of completely cost-free acid and also benzyl ester in benzoin periodontal; it exists in cost-free kind in the leaves along with bark of some plants; In necessary oils in the form of methyl or benzyl esters; in equine pee in the form of its gotten hippuric acid. Benzoic Acid Option is a weak acid, extra powerful than fats. Their chemical properties are comparable, and in addition they can establish salts, esters, acid halides, amides, acid anhydrides, etc, as well as likewise are not conveniently oxidized. The electrophilic alternating action can happen on the benzene ring of benzoic acid, as well as the meta-substituted thing is generally obtained.
