Description:
Benzoic acid is a colorless crystalline solid and a simple aromaticcarboxylic acid. The name is derived from gum benzoin, which was for a long time its only known source. Benzoic acid occurs naturally in many plants and it serves as an intermediate in the biosynthesis of many secondary metabolites. Salts of benzoic acid are used as food preservatives and benzoic acid is an important precursor for the industrial synthesis of many other organic substances. The salts and esters of benzoic acid are known as benzoates.
Benzoic acid is often used as drug or the use of preservative, anti fungal, bacterial, fungal growth, medicinal is painted on the skin, used to treat ringworm of the skin disease. It is used for synthetic fiber, resin, paint, rubber, tobacco industry. Initially benzoic acid is obtained by an interest gum distillation or alkaline hydrolysis and by hippurate hydrolysis. In industrial, benzoic acid is obtained in cobalt, manganese catalyst by air oxidation of toluene; or by phthalic anhydride hydrolysis decarboxylation of benzoic acid and its sodium salt can be used as latex, toothpaste, jam or other food antimicrobial agent, also can be used for dyeing and mordant.
Usage:
1.Used as a chemical reagent and preservative.
2.Benzoic acid is important type food preservative. Under acidic conditions, It has inhibitory effects to mold, yeast and bacteria , but the effect is weak acid producing bacteria. The most appropriate antimicrobial pH values is ranging from 2.5 to 4, generally lower, the pH value is appropriate from 4.5 to 5.
