Lactic Acid Liquid, High Purity, Sour Milk Taste And Strong Moisture Absorption
Overview
Lactic acid is a carboxylic acid with molecular formula of C3H6O3, which contains hydroxyl groups and belongs to α- Hydroxy acid (AHA). In aqueous solution, its carboxyl group releases a proton to produce lactate ion CH3CH (OH) CO-. Pure products are colorless liquids, and industrial products are colorless to light yellow liquids. Odorless and hygroscopic. The relative density is 1.2060 (25 / 4 ℃). Melting point: 18 ℃. The boiling point is 122 ℃ (2KPa). The refractive index Nd (20 ℃) is 1.4392. It can be miscible with water, ethanol and glycerol. The aqueous solution is acidic, PKA = 3.85. It is insoluble in chloroform, carbon disulfide and petroleum ether. It is heated and decomposed under normal pressure. When it is concentrated to 50%, part of it becomes lactic anhydride. Therefore, the product often contains 10% ~ 15% lactic anhydride.
