ISO Factory supply Benzoic acid Powder CAS 65-85-0

Details:

                    Benzoic acid is an aromatic acid organic compound and the simplest aromatic acid with the molecular formula C7H6O2. Originally made from benzoin gum, it is called benzoic acid. The melting point is 122.13 °C, the boiling point is 249.2 °C, and the relative density (15/4 °C) is 1.2659. Appearance is white needle-like or scaly crystals. It sublimates above 100 °C. Slightly soluble in cold water, hexane, soluble in hot water, ethanol, ether, chloroform, benzene, carbon disulfide and turpentine.
                      Benzoic acid is widely found in nature in the form of free acid, ester or its derivatives. It is mainly used for the preparation of sodium benzoate as a preservative, and for the synthesis of drugs and dyes; it is also used for the preparation of plasticizers, mordants, fungicides and spices. It can be prepared by direct oxidation of toluene in the presence of manganese dioxide; or by decarboxylation of phthalic anhydride with steam

Chemical properties
Benzoic acid is the simplest aromatic carboxylic acid. It is aromatic and also has the properties of carboxylic acid. Therefore, two types of chemical reactions can occur, one is the substitution reaction on the benzene ring, and the other is the reaction of the carboxyl group. Benzoic acid is a weak acid, stronger than fatty acids. They have similar chemical properties and can form salts, esters, acid halides, amides, acid anhydrides, etc., and are not easily oxidized. Electrophilic substitution reaction can occur on the benzene ring of benzoic acid, and meta-substitution products are mainly obtained.
