CH3CH (OH) COOH is a monobasic carboxylic acid with three carbon atoms containing a hydroxyl group. Salts and esters of lactic acid are called lactates. Lactic acid is formed during the lactic fermentation of sugar and plays an important role in metabolism.
Low-tonnage chemistry produces lactic acid of 4 grades: pure chemical, pharmacopoeial, technical and food.
When interacting with oxidants, lactic acid decomposes. When oxidized by oxygen or nitric acid in the presence of iron or copper, it is converted into formic acid, acetic acid, oxalic acid, acetic acid, carbon dioxide and pyruvic acid. Of industrial interest is the dehydration of lactic acid to acrylic acid and its reduction to propylene glycol.
Lactic acid is used mainly in two areas: food industry and polymer production, as well as for other industrial purposes.
1) In the food industry, lactic acid is used as a preservative and acidifier. Due to the fact that its salts are well soluble in water, they can also be used in products where pH is important. Lactic acid and its salts are used in beverages, sweets, meat products and sauces. Calcium lactate is added to foods as a source of calcium.
2) In the polymer industry from lactic acid get polylactide.
