Properties of dibutyl fumarate

Dibutyl fumarate (DBF), chemical formula C12H18O4, is a colorless to light yellow transparent liquid with a high boiling point and low volatility. Its solubility in water is low, but it can be miscible with a variety of organic solvents, such as ethanol, ether and so on. DBF has good chemical stability and is not easy to react at room temperature. DBF has good flexibility and cold resistance, which makes it advantageous in some specific applications.

Use of dibutyl fumarate

Dibutyl fumarate is widely used in industry. It is an excellent plasticizer, commonly used in polyvinyl chloride (PVC), polyvinyl acetal (PVB), ethylene-vinyl acetate copolymer (EVA) and other plastics plasticization treatment, can give the material better flexibility and cold resistance. DBF is also used in the paint and ink industry as a solvent or co-solvent to improve product performance. DBF is used as a drug carrier and stabilizer in the field of medicine to ensure the effectiveness and stability of drugs. In the textile industry, DBF is used as a textile auxiliary to improve the softness and wrinkle resistance of fibers. DBF is also used in the fragrance and flavor industry as a solvent and diluent for certain flavors.

Dibutyl fumarate upstream raw material

The main upstream raw materials for the production of dibutyl fumarate include fumaric acid and n-butanol. Fumaric acid is an important organic acid, usually produced by cis-trans isomerization of maleic acid or by hydrolysis from maleic anhydride. n-Butanol, on the other hand, is a common alcohol compound, which is usually produced by petrochemical processes such as oxidation of n-butane or condensation of acetaldehyde. The supply and price of these raw materials directly affect the production cost and market price of DBF. In recent years, due to the tightening of environmental protection policies, the green production technology of upstream raw materials has gradually received attention, especially the improvement in reducing waste emissions and energy consumption.

Dibutyl fumarate downstream products

Dibutyl fumarate is an important intermediate and additive, and its downstream products are involved in many fields. In the plastics industry, DBF is used to produce a variety of plasticized plastic products, such as wire and cable, floor leather, artificial leather, hose and so on. The use of DBF in coatings and inks can improve the flexibility and adhesion of products, and is suitable for architectural coatings, automotive coatings and printing inks. In the field of medicine, DBF, as a drug stabilizer and carrier, can be made into various pharmaceutical preparations. The application of DBF in textile finishing agents and fragrance products has also led to the development of related industries.

Dibutyl fumarate storage method

Storage of dibutyl fumarate requires care to prevent leakage and contamination. It should be stored in a cool, dry, well-ventilated warehouse, away from fire and heat sources, and avoid direct sunlight. DBF should be stored separately from oxidants, acids and bases to prevent chemical reactions. Storage containers shall be well sealed and made of corrosion resistant material to prevent leakage and volatilization. When handling DBF, wear protective equipment to prevent skin contact and inhalation of vapors. The warehouse shall be equipped with appropriate fire extinguishing equipment to deal with sudden fire accidents.

Market Prospects and Challenges

The market outlook of dibutyl fumarate is influenced by several factors. With the continuous development of plastics, coatings, pharmaceuticals and other industries, the demand for DBF is expected to grow steadily. The increasingly stringent environmental regulations also promote the application of DBF in green chemical industry. The market also faces some challenges, such as fluctuations in upstream raw material prices, environmental policy pressures, and technical barriers. In order to meet these challenges, companies need to constantly innovate, improve production efficiency, develop new products and new application areas, and pay attention to environmental protection and sustainable development.

Conclusion

As a multifunctional chemical, dibutyl fumarate has broad application prospects. Greater market value can be achieved by optimizing production processes, improving storage methods and expanding downstream markets. In the face of market competition and environmental protection requirements, the industry needs to constantly innovate and adjust to adapt to market changes and policy environment. Dibutyl fumarate will continue to play an important role in the future chemical industry and drive the development of related industries.
