Lactic acid is an important organic acid, the production and consumption of the second organic acid after citric acid, some data show that the consumption of lactic acid accounted for about 15% of the total consumption of organic acids. In recent years, due to the expanded application of L-lactic acid in biodegradable plastics, its demand will have a larger rate of growth, some people predict that it is possible to catch up with or exceed citric acid in a few years. Lactic acid exists widely in nature and is found in living organisms.
In medicine, sodium lactate is used to prevent acidosis, iron lactate, calcium lactate and so on are raw materials for pharmaceutical industry, ethyl lactate is a spice, butyl lactate is a good additive for paint, but also an important raw material for plasticizer and improver in plastic industry; Used as a rust remover in the electroplating industry.
Chemical property
Molecular weight 90.08. Melting point 16.8ºC, boiling point 122ºC(1.8665 ~ 1.9998kPa), Ka = 1.38×10-9(25ºC). Industrial products are liquid with sour taste, soluble in water, ethanol, slightly soluble in ether, insoluble in chloroform, carbon disulfide and petroleum ether. Lactic acid is easily miscible with water and is not easy to crystallize. The concentration of lactic acid is more than 60%, and it has high hygroscopicity. Therefore, commercial lactic acid is usually 60% solution, the lactic acid content of pharmacopoeia grade is 85.0% ~ 90.0%, and the lactic acid content of food grade is more than 80%. Usually, lactic acid is colorless or slightly yellow liquid, which can be purified by vapor distillation, and can be obtained by repeated fractionation under vacuum conditions of 67 ~ 133Pa to obtain high-purity lactic acid, and then obtain crystalline lactic acid of monoclinic crystals.
