Hydrogenation C9 properties

Hydrogenated C9, also known as hydrogenated C9 petroleum resin, is the product obtained by treating C9 fraction through hydrogenation process. Its main components include styrene, diene, alkylbenzene and other aromatic hydrocarbons. After hydrogenation treatment, the degree of saturation is increased, the color becomes lighter, and the performance is more stable. Hydrogenated C9 has good weather resistance, oxidation resistance, low odor and high softening point, which makes it show excellent performance in various applications. Hydrotreating can also reduce the presence of unsaturated bonds, reduce the acid value of the resin, and improve its thermal and chemical stability.

Hydrogenation C9 use

Adhesives and sealants

Hydrogenated C9 is widely used in the field of adhesives and sealants, especially in hot melt adhesives. Its excellent adhesion and stability make hot melt adhesives perform well in packaging, book binding, furniture manufacturing, etc. Hydrogenated C9 can also improve the adhesion and flexibility of the sealant, which is suitable for sealing materials in the construction and automotive industries.

Coatings and Inks

Hydrogenated C9 petroleum resins also have important applications in coatings and inks. It can improve the gloss, weather resistance and drying speed of the coating. In ink, hydrogenated C9 can improve the color vividness and adhesion of ink, so that the quality of printed matter is higher, especially suitable for high-quality printed matter and outdoor advertising.

Rubber and tires

In the rubber and tire industry, hydrogenated C9 is used as a tackifier and reinforcing agent to improve the adhesion and mechanical strength of rubber products. Its low odor and excellent thermal stability make it widely used in tire production, especially in high-performance tires.

Other applications

Hydrogenated C9 is also used in the manufacture of plastic modifiers, textile additives, waterproof materials and insulating materials. Its versatility makes it widely used in many fields and provides diversified solutions for all walks of life.

Hydrogenation C9 upstream and downstream feedstocks

Upstream raw materials

The main upstream feedstock for hydrogenation of C9 is the C9 fraction. The C9 fraction is a by-product of the petroleum cracking process and contains a variety of unsaturated hydrocarbons and aromatic hydrocarbons. In order to produce hydrogenated C9, the C9 fraction needs to be hydrotreated. Hydroprocessing usually requires the use of hydrogen and catalysts, common catalysts such as nickel, cobalt and molybdenum. The hydrogenation process can remove the unsaturated bonds in the C9 fraction and improve the stability and color quality of the product.

Downstream Products

Hydrogenated C9 is an important intermediate chemical product, and its downstream products cover many fields. Downstream products mainly include various types of adhesives, sealants, coatings, inks, rubber products and tires. These products are widely used in daily life and industrial production, providing the necessary raw materials for various production activities.

HYDROGENATED C9 STORAGE METHOD

Storage conditions

Hydrogenation C9 should be stored in a cool, dry, well-ventilated environment, away from direct sunlight and high temperature. The warehouse shall be equipped with appropriate fire prevention facilities to avoid mixing with oxidants, acids and other chemicals. The storage temperature should be kept between 0-30 degrees Celsius to prevent product degradation caused by high temperature and embrittlement caused by low temperature.

Packaging requirements

Hydrogenated C9 is usually packaged in bags or drums. Common packaging materials include polyethylene bags, composite bags and metal drums. Packaging materials should have good sealing and corrosion resistance, prevent moisture and oxygen from entering. Before packaging, the hydrogenated C9 should be fully dried to prevent moisture residue from affecting product quality.

Safety Precautions

When storing and transporting hydrogenated C9, attention should be paid to fire prevention, anti-static and anti-leakage. Warehouses and transport vehicles should be equipped with necessary fire-fighting equipment, and operators should wear protective gloves and masks to avoid direct contact with products. When leakage occurs, it should be covered with inert material in time and cleaned up.

Environmental Protection and Sustainable Development

In the production and use of hydrogenated C9, environmental protection and sustainable development are important aspects that cannot be ignored. Production enterprises should strictly abide by environmental protection laws and regulations, take effective pollution prevention and control measures, and reduce the discharge of waste gas, waste water and solid waste in the production process. The recovery and reuse of hydrogenated C9 is also an important way to achieve sustainable development. Enterprises should actively explore and apply advanced recovery technology to reduce the impact on the environment.

Conclusion

As a chemical product with excellent performance, hydrogenated C9 has a wide range of applications in adhesives, coatings, rubber and other fields. Its production involves a complex hydrogenation process, which requires a stable supply of raw materials and advanced production technology. Reasonable storage and transportation conditions are an important guarantee to ensure product quality and safety. In the future development, hydrogenation C9 production enterprises should pay attention to environmental protection and sustainable development, strive to reduce the impact on the environment, and enhance the market competitiveness of products. Through continuous technological innovation and management optimization, hydrogenation C9 will show its unique advantages and broad application prospects in more fields.
