[Uses]

benzoic acid is a preservative primarily for use against molds and yeasts. Its performance is classified only as fair against bacteria. Benzoic acid is used in concentrations of 0.05 to 0.1 percent. Although it has a low sensitizing rate, it may cause an allergic reaction in persons sensitive to similar chemicals.

Character: It is white,silkete squama or acercse crystal. It has aslightle smell of benzoin of benzaldehyde. It sublimates at about 100°C,relative density is 1.316,boiliy point is 249.2°C, melting point is 121.7°C-123°C. It is difficult to dissolve water(0.34g/100ml,25°C), It can dissolve boiling water(4.55g/100ml,90°C)ethand, chloroform and ether, fixed oil and naphtha.

[Uses]

Benzoic Acid is a preservative that occurs naturally in some foods such as cranberries, prunes, and cinnamon. it is most often used in the form of sodium benzoate because of the low aqueous solubility of the free acid. sodium benzoate is 180 times as soluble in water at 25°c as benzoic acid. the salt in solution is converted to the acid which is the active form. the optimum ph range for microbial inhi- bition is ph 2.5–4.0. it is used in acid foods such as carbonated bev- erages, fruit juices, and pickles. it is also termed benzoate of soda.
