Benzoic acid of C6H5СООН 2916310000
Benzoic acid C6H5COOH is the simplest monobasic carboxylic acid of an aromatic series.
Benzoic acid - white crystals, poorly soluble in water, well - in ethanol, chloroform and diethyl ether. Benzoic acid, like most other organic acids, is a weak acid (pKa 4.21).
Pure acid has a melting point of 122.4 В° C and a boiling point of 249 В° C. Sublimes easily; distilled with water vapor, therefore, do not concentrate aqueous solutions of benzoic acid by evaporation. Salts of benzoic acid have high bactericidal and anti-septic activity, because of its low toxicity, benzoic acid is widely used as a preservative in the food industry, as an antiseptic agent in medicine, in the perfumery and cosmetic industries, which grows strongly with a decrease in pH.
Benzoic acid is used in the manufacture of phenol, benzyl chloride, caprolactone, as an additive to varnishes that enhance gloss, adhesion and resistance to aggressive environments.
