1. Benzoic acid
Benzoic acid, CAS No. 65-85-0, E210, EINECS No. 200-838-9, chemical formula C7H6O2, molecular weight 122.12.
Benzoic acid is an aromatic acid organic compound and the simplest aromatic acid. Initially made from benzoin gum. Melting point 122.13 ℃, boiling point 249.2 ℃, relative density (15/4 ℃) 1.2659. Its appearance is white needle-like or scale-like crystals. It is mainly used as a preservative, and used in the synthesis of drugs and dyes; it is also used as a plasticizer, mordant, fungicide, and fragrance.
2. Classification of benzoic acid
Benzoic acid is divided into industrial grade, food grade, feed grade, and pharmaceutical grade by application; powder and flake by appearance.
3. Sodium benzoate
Sodium benzoate, CAS No. 532-32-1, E211, EINECS No. 208-534-8, chemical formula C7H5NaO2, molecular weight 144.12.
Sodium benzoate is an organic substance, a white granular or crystalline powder, odorless or slightly with benzoin odor, slightly sweet taste, astringent taste, stable in air, easily soluble in water, its aqueous solution has a pH value of 8, soluble in ethanol.
4. Effective PH of sodium benzoate and benzoic acid
Benzoic acid and sodium benzoate are broad-spectrum anti-microbial reagents, but their antibacterial effectiveness depends on the pH of the food. With the increase of medium acidity, its bactericidal and antibacterial effectiveness is enhanced, and in the alkaline medium, it loses its bactericidal and antibacterial effect. Its optimum pH value for antiseptic is 2.5~4.0. 5.
5. Classification of sodium benzoate
Sodium benzoate is divided into powder, granule/noodle, and column/pellet from appearance.
