Uses and synthesis of DL-3-Hydroxybutyric acid sodium salt powder

DL-3-Hydroxybutyric acid sodium salt powder is widely found in nature, human blood and urine. It is optically active and crystalline in its pure form. The hydroxyl group can be associated, easily soluble in water, ethanol, ether, and easily decomposed by dry steaming. Due to the presence of polar group OH, its acidity is enhanced, and it is easy to esterify with alcohols or acids. DL-3-Hydroxybutyric acid sodium salt polymers can be decomposed by microorganisms in both aerobic and anaerobic conditions, so they can be used in biodegradable plastics, but there is no large-scale industrial production at present.

Applications/Functions of DL-3-Hydroxybutyric acid sodium salt powder

1. DL-3-Hydroxybutyric acid sodium salt powder is mainly prepared by biochemical method or fermentation method, so the yield is low, the cost is high, and the price is expensive, which hinders the research, development and application of biodegradable plastics.
2. DL-3-Hydroxybutyric acid sodium salt can be directly used to produce aliphatic polyester plastics, and sodium 3-hydroxybutyrate can also be copolymer with other compounds to produce plastics with excellent properties.
3. DL-3-Hydroxybutyric acid sodium salt is a monomer for the preparation of biodegradable plastics, and its polymeric ester PHB (Poly 3-hydroxybutyrate) has high melting point, high crystallinity and tensile strength, as well as complete biodegradability, biocompatibility, Uv resistance and low oxygen permeability properties.
