Name: Benzoic Acid
Other name: carboxybenzene, phenylformic acid, Benzoicum Acid
CAS NO.:65-85-0
Molecular Formula:C7H6O2
Appearance and properties: Flake or acicular crystal
Benzoic acid is scaly or needle shaped, with the smell of benzene or formaldehyde, flammable. The relative density is 1.2659. The melting point is 122.4ºC, the boiling point is 249ºC, and the refractive index is 1.504. Vapors are volatile. Flash point (close cup) 121-123ºC. Slightly soluble in water, soluble in ethanol, methanol, ethyl ether, chloroform, benzene, toluene, carbon disulfide, carbon tetrachloride and turpentine. It sublimated rapidly at 100 degrees and evaporated at the same time as steam. Benzoic acid is widely found in nature in the form of free acids, esters or their derivatives. In the form of free acid and benzyl ester, for example, in the leaves and stems of some plants, there are free forms in the leaves and stems of some plants, in the form of methyl or benzyl esters in the essence, and in the form of its derivative, equine acid in horse urine.

Function
Benzoic acid can effectively restrain the mold, yeast and oxygen activity of bacteria, staphylococcus aureus, salmonella and other harmful microorganism growth and reproduction, but for anaerobic bacillus bacteria and lactobacillus acidophilus beneficial microbes such as null and void, almost against the effect of development was stronger than the sterilization effect, so as to effectively prolong food to save time, and keep the original flavor of food.
