Description:
Citric acid (2-hydroxy-1,2,3-propanetricarboxylate acid) (C6H8O7) is a crystalline substance of white color, melting point 153 °C, soluble in water, soluble in ethanol, slightly soluble in diethyl ether. Weak tribasic acid.
Citric acid is an important product of metabolism in living organisms involved in the tricarboxylic acid cycle and glyoxylate cycle.

Receiving:
The main industrial method of producing citric acid by the fermentation of sugar, treacle or molasses with fungal strains of Aspergillus niger.
Possible synthesis of citric acid by the reaction of ketene with oxaloacetic acid anhydride.

Application:
Citric acid monohydrate is widely used:
• in food industry as acidity regulator, an antioxidant and a preservative (E330); for protection of fats from damage, in as a food additive in confectionery, in the production of juices, canned food and etc.
• as a component of buffer solutions;
• in the pharmaceutical industry as a component of many drugs (Na citrate — anticoagulant);
• as a reagent for removing rust and scale from metal surfaces when electrotrain copper, cancerously solutions in setcapacity, in the production of diatoma;
• for the citric acid esters used as plasticizers etc.
