Sebacic Acid

Azelaic acid, also known as azelaic acid, has important applications in many fields such as chemical industry, medicine, and materials. In the chemical industry, it is a key raw material for the synthesis of polyester resins and plasticizers. Taking polyester resins as an example, azelaic acid and polyols can be polymerized to obtain polyesters with excellent performance. Such polyesters are widely used in coatings, adhesives and other products, such as some high-performance coatings. With the synthesis of azelaic acid, polyesters have good weather resistance and chemical corrosion resistance, which can protect the surface of the coated object for a long time. In terms of plasticizers, azelaic acid-derived plasticizers can effectively improve the flexibility and plasticity of plastics. For example, in the production of some plastic products, the addition of plasticizers containing azelaic acid can make plastic products easier to process and shape, and it is not easy to crack when used. In the field of medicine, azelaic acid has shown unique medicinal value. Because of its antibacterial, anti-inflammatory and regulating keratinocyte differentiation, it is often used in the treatment of skin diseases. For example, acne vulgaris, azelaic acid can inhibit the growth of Propionibacterium acne, reduce inflammation, and improve abnormal keratosis of the hair follicle, thereby relieving acne symptoms. Clinical studies have shown that the use of azelaic acid-containing preparations has a significant effect on patients with mild to moderate acne, and compared with some traditional anti-acne drugs, the side effects are smaller. In addition, in the treatment of melasma, azelaic acid can reduce melanin synthesis by inhibiting tyrosinase activity, thereby reducing melanin synthesis, which brings good news to many melasma patients. In the field of materials, azelaic acid can be used to synthesize special engineering plastics. Taking polyamide as an example, the polyamide formed by the polymerization of azelaic acid and diamine compounds has high melting point, high strength and excellent chemical stability. Such polyamide materials are widely used in automotive manufacturing, aerospace and other fields. In the manufacturing of automotive engine peripheral components, the use of polyamide materials can withstand high temperatures and mechanical stress to ensure the stable operation of automobiles; in the aerospace field, it can meet the requirements of high performance and lightweight materials for aircraft, and help improve the performance of aircraft.

Azelaic acid, also known as azelaic acid, is a dicarboxylic acid that has many applications in the chemical and pharmaceutical fields. Its preparation methods generally include the following: 1. ** Oxidative cracking method of natural oils **: This is a more traditional method. First take natural oils containing oleic acid, such as animal oils or certain vegetable oils. Under specific conditions, oleic acid is oxidized and cracked at the double bond by strong oxidants, such as potassium permanganate and ozone, and then produces azelaic acid. This process requires strict control of the reaction temperature, time and oxidant dosage. Excessive temperature or excessive oxidant can easily cause excessive oxidation and reduce the yield and purity of azelaic acid. However, its raw materials are naturally easy to obtain and have been widely used in the past. 2. ** Acrylonitrile electrolytic dimerization method **: Using acrylonitrile as the starting material, in an electrolytic system composed of a specific electrolyte and electrode materials, acrylonitrile undergoes a dimerization reaction to form glutaronitrile intermediates. Then the intermediate is hydrolyzed, and the nitrile group is converted into a carboxyl group to obtain azelaic acid. This method has the advantages of relatively mild reaction conditions and high product purity. However, it has high requirements for electrolytic equipment and processes. It is necessary to properly handle issues such as electrode loss and electrolyte recovery. 3. ** Microbial fermentation method **: A green preparation method that has emerged in recent years. Screen specific microbial strains, such as certain Pseudomonas or yeasts. Using suitable nutrients such as carbon and nitrogen sources as the medium, microorganisms grow and metabolize in it, and convert the substrate into azelaic acid through their own enzyme system. This process is usually carried out at room temperature and pressure, which is environmentally friendly, and the product has the advantage of high optical purity. However, the fermentation cycle of microorganisms is relatively long, and the fermentation conditions need to be carefully regulated to ensure good growth of microorganisms and efficient acid production.

Sebacic Acid (Sebacic Acid), when used, there is a need to pay attention to it. Its nature is peaceful, but it should not be ignored. First, it has a certain degree of decay. If it is accidentally damaged in the muscles, it is advisable to wash it with a large amount of water immediately, and check the appearance of the muscles. If there is any problem, ask for it. If it is important to the eyes, it is even more important to wash it with water immediately. Do not rub it, and it will be treated immediately. For the second time, when it is stored, it should be placed in a place where it is dry and clear. Avoid high temperatures due to fire, or risk of burning. It is also not allowed to mix with oxidizers and other substances to prevent biochemical reactions and cause health hazards. Furthermore, the use of pesticides should follow the correct operation process. In the process of work, the workers should take appropriate precautions, such as protective clothing, gloves, eyes, etc., to ensure their own safety. And the work should have good communication, so that the waste can be obtained and discharged, so as to avoid inhalation, and health. In addition, pay attention to the separation of diacid in the environment. If it is accidentally leaked, it will quickly stop the leakage of pollution and limit access. A small amount of leakage can be mixed with sand, lime or ash, and collected in containers with dry, dry, and dirty materials. Large amount of leakage, embankment or dig a pit to contain, cover with foam to reduce steaming damage, move to a tank or a collector with a pump, recycle or store in a storage area. In this way, it can ensure the safety of use and avoid accidents.
