Succinic acid, also known as succinic acid, has a molecular weight of 118.09, is a colorless crystalline substance with an acidic taste and is flammable. There are two crystal forms with a relative density of 1.572 (25/4 ℃). Dissolving characteristics: 1g is soluble in 13ml cold water, 1ml boiling water, 18.5ml ethanol, 6.3ml methanol, 36ml acetone, 20ml glycerol, and 11ml ether.
Succinic acid
It is almost insoluble in benzene, carbon disulfide, carbon tetrachloride, and petroleum ether. It can react with alkali, and can also undergo esterification and reduction reactions. Heating dehydration generates succinic anhydride. Nucleophilic substitution reactions can occur, where hydroxyl groups are replaced by halogen atoms, amino compounds, acyl groups, etc. The natural source of succinic acid is mainly amber formed by burying plant resin underground for a long time, and it also exists in the tissues of various plants and animals.
The main natural source of succinic acid is amber
The function of succinic acid
At a concentration of 2mg/ml, bactericidal succinic acid has inhibitory effects on Staphylococcus aureus, Staphylococcus aureus, as well as Salmonella typhi, Pseudomonas aeruginosa, Proteus mirabilis, and Shigella.
Antioxidant succinic acid is known as a youthful and anti-aging medicine, with antioxidant and anti-aging effects. Many cosmetics now contain succinic acid or amber granules.
Europeans consider succinic acid as an important hangover suppressant, which can reduce dependence on alcohol and, interestingly, quickly neutralize ingested alcohol. A pill containing approximately 0.1 grams of succinic acid can restore a drunken person’s normal ability in about 15 minutes.
In ancient China, amber was used as medicine to treat rheumatism and other diseases, promoting blood circulation and removing blood stasis. In addition, succinic acid can enhance the human immune system and make people energetic. It also has soothing, diuretic, and even detoxifying effects.
The use and application of succinic acid
Chemical industry: Succinic acid is widely used in the synthesis of various chemical products, such as plasticizers, resins, and coatings. It can react with alcohols to form succinate, which is used to manufacture environmentally friendly plasticizers and replace phthalate plasticizers, reducing environmental pollution. Meanwhile, succinic acid is also a precursor for the production of 1,4-butanediol (BDO), which can be further used for the synthesis of polyurethane, elastomers, and engineering plastics.
In the field of medicine, amber is a resin secreted by trees that has been buried underground for millions of years. After being petrified by geological processes in the earth’s crust, it is named amber and has an undeniable position in scientific research and other fields. The unique component in amber, succinic acid, also plays an important role in the field of medicine. Succinic acid and its derivatives have important applications in the field of medicine. It can be used as a drug intermediate for the synthesis of antibacterial, anti-inflammatory, and other active drug molecules. In addition, succinic acid also has pharmacological effects such as anti-spasms, expectorants, and diuresis.
Food industry: In the food industry, succinic acid can be used as an acidity regulator, antioxidant, and yeast nutrient to improve the taste and shelf life of food.
Agriculture: Succinic acid is an important raw material for producing plant growth regulators and microbial fertilizers, which helps to increase crop yield and disease resistance.
In the field of environmental protection: With the increasing awareness of environmental protection, the application of bio-based succinic acid is becoming more and more widespread. It can be used as a raw material for biodegradable plastics, such as polybutylene succinate (PBS), which has good biodegradability and mechanical properties and is widely used in packaging, agricultural films, and disposable products.
