Uses and synthesis of Lactic acid powder

Lactic acid powder is an important organic acid, Lactic acid CAS 50-21-5, also known as 2-hydroxypropionic acid, α-hydroxypropionic acid, there is an asymmetric carbon atom in the molecular structure, the formation of two rotary isomers of d-body, l-body and racemic dl-body, a total of three optical isomers.1780 Scheele in the sour milk, the product was obtained. In 1780, Scheele obtained this product in sour milk, so it was named Lactic acid Raw Materials.

Applications / Functions of Lactic acid powder

1. Lactic acid powder is mainly used in spice, food, beverage industry, but also is the raw material of medicine, chemical industry, leather, printing and dyeing industry.
2. Lactic acid CAS 50-21-5 Used as experimental reagent, edible spice, preservative, plasticiser and adhesive, also used in pharmaceutical industry.
3. Antimicrobial potentiometers
4. Lactic acid Raw Materials Make important acidifier, have special astringent sour taste.

Physicochemical Property of Lactic acid powder

Lactic acid powder is a white powder, the industrial product is colourless to light yellow liquid. It is odourless and hygroscopic. Miscible with water, ethanol, glycerol, insoluble in chloroform, carbon disulfide and petroleum ether.

Production methodprocess of Lactic acid powder

• Acetaldehyde and hydrocyanic acid are used as raw materials to produce lactic nitrile, which is hydrolysed to obtain crude lactic acid, which is then hydrolysed to obtain Lactic acid by ethanol esterification CAS 50-21-5. 
• Hydrolysis of acrylonitrile to crude lactic acid, then hydrolysed by methanol esterification to Lactic acid Raw Materials
