Properties of isophorone

Isoborone (Isophorone, chemical formula C9H14O) is an unsaturated epoxy compound, belonging to the class of ketones. It appears as a colorless to yellowish liquid with an odor similar to mint and camphor. Isophorone has a boiling point of about 215°C, a flash point of 90°C and a density of about 0.922g/cm³. The solubility in water is low, but it can be miscible with most organic solvents, such as ethanol, ether, benzene and acetone. Its main chemical properties include good stability and strong acid and alkali resistance, and it is not easy to spontaneous combustion or explosion.

Isophorone use

Isophorone has a wide range of uses in the chemical industry. It is used as a solvent, especially in the paint, ink and resin industries. Its good solubility makes it an important component of resin dissolution. Isophorone is used as an intermediate in the synthesis of a variety of chemical products, including pesticides, pharmaceuticals and fragrances. It is also used as a polymer modifier and photoinitiator to improve the physical and chemical properties of the material. Isophorone is also used in the metal cleaning and electronics industries to effectively remove dirt and impurities.

Upstream raw materials

The production of isophorone uses acetone as the main raw material. Acetone is catalytically hydrogenated to isopropanol, which is then synthesized via diketonation to isophorone. This process typically involves a multi-step reaction, including a hydrogenation reaction, a dehydration reaction, and a ring-closing reaction. The production process also requires the use of catalysts, such as nickel or copper-based catalysts, to improve reaction efficiency and product selectivity. It is also necessary to control the reaction conditions, such as temperature and pressure, to ensure product purity and yield.

Downstream Products

The downstream products of isophorone are diverse and cover multiple industries. The most important downstream products are isophorone diamine (IPDA) and isophorone diisocyanate (IPDI), which have important applications in the polyurethane industry. IPDA is used to produce high-performance coatings, adhesives and sealants, while IPDI is widely used in elastomers and coatings. Isophorone is also used in the synthesis of other specialty chemicals, such as light stabilizers, antioxidants and pharmaceutical intermediates, further expanding its range of applications.

storage method

The storage of isophorone requires attention to several key factors. Due to its low flash point, isophorone should be stored in a cool, well-ventilated warehouse, away from fire and heat sources. Store in well-sealed containers to prevent leakage and volatilization. Storage containers shall be made of corrosion resistant materials such as stainless steel or special plastics to avoid direct contact with oxidants, acids and alkalis. The storage area should be equipped with appropriate fire extinguishing equipment, such as foam fire extinguishers and dry powder fire extinguishers to prevent fire accidents.

Safety and environmental protection

Strict safety measures need to be observed when handling and using isophorone. Due to its toxicity and irritation, operators should wear protective equipment such as gloves, goggles and protective clothing to avoid skin contact and inhalation of vapors. In the event of a leak, the leak area should be quickly isolated, treated with adsorbent materials, and the waste should be safely disposed of as required. In terms of environmental protection, waste and residual liquid of isophorone should be properly disposed of to avoid direct discharge into the environment to prevent pollution of soil and water bodies.

market and prospect

The market demand for isophorone comes mainly from the coatings, inks and polymer industries. With the advancement of industrialization and the development of new material technology, the application range and market demand of isophorone will continue to grow. Especially in high-performance coatings and environmentally friendly solvents, isophorone has significant advantages. With the increasing focus on green chemistry and sustainable development, the production process and application areas of isophorone will be further optimized and expanded to meet the diverse needs of the market.

Conclusion

As an important chemical raw material, isophorone has excellent chemical and physical properties and plays a key role in many industries. Its upstream raw material is mainly acetone, which is produced through a multi-step reaction, while its downstream products are involved in many fields, including the coatings, pharmaceutical and polymer industries. The storage and handling of isophorone requires strict compliance with safety and environmental standards to ensure its safe use and environmental protection. With the growth of market demand and technological progress, the application prospect of isophorone will be broader, providing important support for the development of chemical industry.
