Decanediol Properties

Decanediol (1,10-Decanediol), chemical formula C10H22O2, is a difunctional saturated aliphatic alcohol. It often appears as a white crystalline solid or powder, with a certain degree of viscosity and hygroscopicity. Decanediol has a high melting point (about 70-74°C) and a high boiling point (about 280-290°C), which makes it thermally stable in many applications. Decanediol has low volatility and good solubility and is soluble in water, alcohols and certain organic solvents.

Decanediol use

Decanediol is widely used in industry. It is an important intermediate for the synthesis of polyurethane, polyester and epoxy resin and other polymer materials. Decanediol acts as a plasticizer to increase the flexibility and durability of the material. It is widely used in cosmetics and personal care products, as a moisturizer, lubricant and solvent, which can improve the texture and feel of the product. In the pharmaceutical field, decanediol is used as a stabilizer and carrier for pharmaceutical preparations. It also has important applications in the fields of lubricants, coolants and antifreeze.

Upstream raw materials

The production of decanediol typically involves the hydrogenation of decanoic acid (Decanoic acid) or decanol (Decanol). Capric acid is a saturated fatty acid extracted from natural oils (such as coconut oil and palm kernel oil) and can be converted to decanol by catalytic hydrogenation. Decanediol is then produced by dehydrogenation or a further catalytic reaction. Another common upstream feedstock is nonanoic acid, which is oxidized to nonanol, which is further converted to decanediol. In general, the production of decanediol relies on fatty acids and their derivatives, and the production process is relatively complex and requires efficient catalysts and reaction conditions.

Downstream Products

The downstream products of decanediol are diverse and involve many high value-added industrial fields. Through polymerization, decanediol can be used to produce polyurethane foams, elastomers and adhesives, which are widely used in the construction, automotive and electronics industries. Decanediol is also an important raw material for polyester resins used in the production of coatings, fibers and plastics. The use of decanediol in personal care products produces a variety of skin and hair care products that enhance moisture retention and stability. In the pharmaceutical industry, decanediol is used as pharmaceutical excipients to improve the solubility and stability of drugs.

Production process

The production of decanediol involves a multi-step chemical reaction, typically including hydrogenation, dehydrogenation, and distillation processes. Decanediol is prepared by catalytic hydrogenation of decanoic acid or decanol, and then by oxidation or dehydrogenation reaction. These reactions need to be carried out under high temperature and high pressure conditions, and high efficiency catalysts are required. After the reaction, decanediol is purified by separation techniques such as distillation and rectification. Modern production processes also include continuous reactors and automated control systems to improve production efficiency and product quality.

storage method

Due to its physical and chemical properties, decanediol needs to be protected from moisture and oxidation during storage. Should be stored in a sealed container, placed in a cool, dry, well-ventilated place, avoid contact with oxidants, strong acid and strong alkali. Decanediol is highly hygroscopic, and long-term exposure to the air will absorb moisture and affect its quality and performance. Therefore, during storage and transportation, contact with air should be minimized. The temperature of the storage environment should not be too high to prevent decanediol from decomposing or deteriorating.

Market Prospects

With the continuous development of the global industry, the demand for decanediol continues to grow. Especially in the field of high performance materials, personal care products and medicine, the demand for decanediol is particularly urgent. The trend of green chemical industry and sustainable development has also promoted the improvement of decanediol production technology and the diversification of raw materials. In the future, with the continuous emergence of new materials and new applications, the decanediol market will maintain steady growth. The integration of the industrial chain and technological innovation will further improve the production efficiency and product quality of decanediol.

Conclusion

As an important chemical intermediate, decanediol has excellent physical and chemical properties and a wide range of applications. By continuously improving the production process and optimizing the source of raw materials, the production efficiency and quality of decanediol can be further improved. With the increase in market demand and the development of new applications, the decanediol industry will usher in a broader development prospects. In the future development, decanediol will continue to play an important role in the fields of polymer materials, personal care products and medicine, and promote the progress and development of related industries.
