Molecular formula :
nature : also known as 2-hydroxy acid. Because molecular asymmetry is a carbon atom, two optical isomers. (1), L-lactate, or l - (+) - lactic acid, the temperature 53 ° C (from the acid or chloroform crystallization). Specific rotation [alpha] 21.22546.1 +2.6 ° (2.5 grams / 100 ml of water). Dissolved in water, ethanol, is not soluble in chloroform. Many of its salts is L-body. (2) D-lactate or d - (-) - lactate, the temperature 52.8 ° C (isopropanol from the ether or crystallization). Polarimetry [alpha] 21.5546 +2.6 ° (8 grams / 100 ml of water). Dissolved in water, ethanol, acetone, ether, glycerol, is not soluble in chloroform. Many of its salts is dextral body. L-contour the body and dextral mix in racemic or dl-lactic acid, white crystals. The melting point of 16.8 ° C The boiling point of 122 ° C (1.8 kPa, 14 mm Hg), 82 ~ 85 ° C (66.6-133 Pago 2-8-1 mm Hg). Dissolved in water, ethanol, ethyl ether-soluble, non-soluble in chloroform and petroleum ether. Lactic acid is widely used in the food, leather, textile, pharmaceutical, plastics and other industries. It is also the body's metabolism of sugar within important intermediates. From starch, potatoes, molasses, milk or lactose fermentation Preparation of oxidation.
