Dodecanedioic Acid(DDDA)

Dodecanedioic acid (DDDA) has a wide range of uses and is useful in various fields. First, in the field of synthetic fibers, DDDA has made a lot of progress. It can be condensed with binary amines to make polyamide synthetic fibers with excellent performance. This fiber has high strength, high wear resistance and good chemical stability, and is often used in the production of high-grade fabrics, industrial canvas, cables, etc. Fabrics are selected for their durability and crisp characteristics; ropes rely on their toughness and are used for navigation, hoisting and other operations. Second, in the field of engineering plastics, DDDA is also indispensable. By condensing with diols, polyester engineering plastics can be obtained. This kind of plastic has good mechanical properties and excellent dimensional stability, and is widely used in the manufacture of automotive parts, electronic and electrical shells, etc. In automobiles, it can be used as a peripheral part of the engine, because it can withstand high temperature and mechanical stress; in electronic and electrical appliances, it can be made into a shell to protect the internal precision components. Third, in the fragrance industry, DDDA is an important raw material. After a series of chemical reactions, fragrance products with unique aroma can be prepared. Such fragrances have an elegant and long-lasting aroma, and are often used to prepare perfumes, cosmetics, detergents, etc., adding a charming fragrance to the product. Fourth, in the manufacture of lubricants, DDDA has a significant effect. The lubricant made from it has excellent lubrication performance, excellent wear resistance and oxidation resistance. It can be used for metal processing, mechanical operation, etc., to reduce friction and wear between components and prolong the service life of machinery. In addition, in the coating industry, DDDA participates in the synthesis of coatings with good adhesion, corrosion resistance and weather resistance. It can be used for surface coating of buildings, ships, bridges, etc., to protect the matrix material from external erosion.

Dodecanedioic acid (DDDA) is widely used in various fields of chemical industry. Looking at its market prospects, there are many positive signs. In the past, DDDA relied more on imports, with high prices but less supply. However, today is different from the past. Our country has advanced scientific research, improved processes, and increasing local production. In the nylon manufacturing industry, DDDA is a key raw material. Nylon has many uses, from clothing to industrial products, and the demand is constant. Therefore, the demand for DDDA is also rising. Furthermore, in the field of lubricating oil, the esters made by DDDA have outstanding performance and can improve the quality of lubricating oil. With the booming development of the machinery industry and the increasing demand for high-end lubricating oil, the market for DDDA in this field will also expand. And the wind of environmental protection is getting stronger, DDDA is becoming more and more popular in the preparation of green chemical products because of its biodegradability. Many companies want to make a green transformation, and DDDA has become a good choice. However, although the market prospect is beautiful, there are also challenges. The international situation is changeable, and the price of raw materials fluctuates or affects costs. And the competition in the same industry is becoming increasingly fierce. If you want to win a place in the market, you need to continuously improve technology, control costs, and improve quality. In general, the dodecanedioic acid market has broad prospects, and opportunities and challenges coexist. If the industry can grasp it well and take advantage of the situation, it will be able to harvest a lot in the chemical market.

Dodecanedioic acid (DDDA), the process of manufacturing can be investigated. The method mostly starts with butadiene, and is formed by the process of transformation. At the beginning, butadiene, carbon monoxide and water, under the appropriate catalytic equipment, the reverse carbonylation is carried out to obtain methyl adipate. This step requires precise control of the degree and force, so that the reaction can be carried out. In addition, the re-oxidation of methyl adipate and hexanediol. The catalyst is used to help the reaction efficiency. The oxidation of hexanediol is reversed, and the dodecanedioic acid is obtained. The oxidation, the oxidation and the reaction environment used, all have an impact on the quality of the product. It is also made by the method of microbial leavening. For specific microorganisms, in a culture rich in carbon sources, nitrogen sources, etc., at an appropriate temperature and pH value, microbial substitution can generate dodecanedioic acid. However, this method needs to pay attention to the cultivation of microorganisms to maintain their activity and acid ability. In addition, the synthesis of microbial leaven can produce dodecanedioic acid, each with its own unique needs, and it is used according to different needs.

Dodecanedioic acid (DDDA), its white color and good crystal shape, is a solid state at room temperature, like powder or crystal. The melting point is between 128 and 130 degrees Celsius. At this temperature, the solid phase will gradually change to the liquid phase. This property is widely used in the processing of materials. The boiling point is about 390 degrees Celsius. At high temperature, the molecular movement intensifies, causing it to change from liquid to gaseous. DDDA has a density of nearly 1.22 g/cm ³, which is similar to that of common organic matter. It is slightly soluble in water, because although there are polar carboxyl groups in the molecule, the long carbon chain is lipophilic, resulting in poor water solubility. However, it is easily soluble in organic solvents such as ethanol and acetone, because these solvents can form intermolecular forces with DDDA molecules, which can help them disperse and dissolve. From a chemical point of view, DDDA contains two carboxyl groups and is quite active. It can be esterified with alcohols to form dodecanedioic acid esters, which are often used as plasticizers to improve the flexibility of materials. When reacted with bases, corresponding carboxylates are formed, which are used in the field of surfactants. Because of its physicochemical properties, it is an important raw material in many industries such as chemical and materials.

The price of dodecanedioic acid (DDDA) is affected by various factors. First, the trend of supply and demand is the key. If the market demand for DDDA is strong, such as in the synthesis of special polyester, nylon and other industries, the demand increases sharply, and the supply is limited, the price will rise; on the contrary, if the demand is weak and too much production causes oversupply, the price will drop. Second, the cost of raw materials also has a significant impact. DDDA often uses butadiene as raw materials. If the price of raw materials fluctuates, the cost of DDDA will change accordingly. If the price of raw materials rises, the manufacturer may raise the price of DDDA in order to ensure profits; if the price of raw materials decreases, DDDA may also reduce the price to increase competitiveness. Third, the process technology factors should not be underestimated. Advanced and efficient production processes can reduce production costs. If an enterprise has a unique process that can produce efficiently and with excellent quality, there will be more room for pricing, or low-price competition due to low costs, or high-price sales due to excellent quality. Fourth, the market competition situation is related to price. If there are many DDDA manufacturers in the market and the competition is fierce, in order to compete for share, the manufacturers may reduce prices and promote sales; if the market is monopolized by a few enterprises, they have strong control over prices and can set prices according to their own interests. Fifth, the policy and regulatory environment has an impact. Environmental protection policies are stricter, and enterprises may meet environmental protection standards or increase pollution control costs, resulting in higher DDDA costs and higher prices; trade policies such as tariff adjustments will also affect import and export prices.
