Butanoic acid, 3-hydroxy-, monosodium salt - Reference Information
| overview | sodium 3-hydroxybutyrate is widely found in nature, human blood and urine. Exhibiting optical activity, pure state crystallizable. Hydroxyl groups can associate, easily soluble in water, ethanol, ether, dry evaporation and easy decomposition. Due to the presence of polar group OH, its acidity is enhanced, and it is easy to undergo esterification reaction with alcohol or acid. The polymer of sodium 3-hydroxybutyrate can be decomposed by microorganisms under aerobic or anaerobic conditions, so it can be applied to biodegradable plastics, but there is currently no large-scale industrial production. |
| use | sodium 3-hydroxybutyrate is mainly prepared by biochemical methods or fermentation methods, so the yield is low and the price is high, which hinders the research, development and application promotion of biodegradable plastics. Sodium 3-hydroxybutyrate can be directly used to produce aliphatic polyester plastics, and sodium 3-hydroxybutyrate can also be copolymerized with other compounds to produce plastics with excellent performance. Sodium 3-hydroxybutyrate can be directly used to produce aliphatic polyester plastics, and sodium 3-hydroxybutyrate can also be copolymerized with other compounds to produce plastics with excellent performance. For example, if it is alternately copolymerized with aromatic polyester, it can produce copolyester products (CPE) with different characteristics and excellent performance; it can also carry out amine ester exchange reaction with polyamide (nylon) to synthesize polyamide ester copolymer (CPAE), which has the advantages of high melting point and high tensile strength; in addition, sodium 3-hydroxybutyrate and general-purpose plastics (PE,PP,PS,PVC) Blending can be made into bio-disintegrating plastics. Due to the addition of sodium 3-hydroxybutyrate, such materials lose their mechanical properties and shapes, and can obtain the same environmental damage as biodegradable plastics through composting. The advantages of harm. 3-hydroxybutyric acid is a monomer for preparing biodegradable plastics. its polymeric ester PHB (Poly 3-hydroxybutyrate) has high melting point, high crystallinity and tensile strength, as well as biodegradability, biocompatibility, ultraviolet resistance and low oxygen permeability. |
| Preparation | Sodium 3-hydroxybutyrate is prepared by hydrolysis reaction: Propylene oxide is treated with HCN, and the obtained intermediate product hydroxynitrile is hydrolyzed. The reaction formula is as follows: Another similar method is to use Kolbe method nitrile synthesis: olefin is used as raw material, reacted with hypochlorous acid to obtain hydroxychlorinated alkane, cyanidation, and finally hydrolysis: these two methods have simpler reactions and fewer by-products. However, due to the use of a large amount of cyanide, it is a highly toxic substance, causing harm to operators and polluting the environment. It can also be prepared by the hydrolysis of β-butyrolactone: acetaldehyde reacts with enone to generate β-butyrolactone, and then hydrolyzed under acidic conditions: this method has few reaction steps, does not require too high temperature and pressure, and is easy to achieve Continuous production has the potential for industrial synthesis. |
| Biological activity | 3-Hydroxybutyric acid sodium (β-Hydroxybutyric acid sodium) is an elevated metabolite in type I diabetes. 3-Hydroxybutyric acid sodium can adjust the properties of membrane lipids. |
