Properties of isononanoic acid

Isononanoic acid is an important organic compound with the chemical formula C9H18O2. It is a saturated fatty acid with low volatility and high thermal stability. The isononanoic acid is a colorless liquid with a slight characteristic odor. Its molecular structure contains a carboxyl group (-COOH), which makes it acidic. The melting point is around -30°C and the boiling point is around 254°C. Due to its large molecular weight, isononanoic acid has a low vapor pressure and is not volatile at room temperature. Inonanoic acid has good chemical stability and is not easily oxidized or decomposed, which makes it show superior performance in a variety of applications.

Use of isononanoic acid

Isononanoic acid is widely used in chemical and industrial fields. It is a key intermediate in the manufacture of plasticizers, which are used to enhance the flexibility and durability of plastics and are widely used in PVC products. The isononanoic acid is used in the production of lubricating oil additives, which can effectively improve the oxidation resistance and anti-wear performance of lubricating oil, thereby prolonging the service life of mechanical equipment. isononanoic acid is also used as a surfactant and emulsifier in cosmetics and personal care products for emulsification and stabilization. It is also used in coatings and inks to improve the fluidity and uniformity of the coating.

isononanoic acid upstream and downstream raw materials

In the production process of isononanoic acid, the main upstream raw material is nonene, which is an olefin compound obtained by petroleum cracking. Nonene generates isononanoic acid by oxidation reaction, and the specific reaction usually includes catalytic oxidation and air oxidation. The downstream products of isononanoic acid mainly include various plasticizers, lubricant additives, surfactants, coatings and ink additives. These downstream products are widely used in plastic manufacturing, mechanical lubrication, cosmetics, coatings and other industries, forming a complete industrial chain.

Production process of isononanoic acid

The production process of isononanoic acid mainly includes catalytic oxidation and air oxidation. Catalytic oxidation method is through the reaction of nonene and air at a certain temperature and pressure, under the action of a catalyst to produce isononanoic acid. The catalyst is usually a metal salt such as cobalt or manganese. The advantages of this method are mild reaction conditions and high yield. The air oxidation method is to generate isononanoic acid by direct reaction of nonene with oxygen in the air at high temperature. The advantage of this method is that the process is simple, but it requires higher reaction temperature and longer reaction time.

Iso-nonanoic acid market prospects

With the development of the global economy and the improvement of people's living standards, the demand for plastic products, lubricants, cosmetics and coatings is increasing. As an important raw material for these products, the market demand for isononanoic acid is also increasing. Increasingly stringent environmental regulations requiring the use of more environmentally friendly and efficient chemical products are also driving the expansion of the isononanoic acid market. In the future, isononanoic acid will have a broader application prospect in the field of plasticizer and lubricant additive.

Isononanoic acid storage method

The storage of isononanoic acid requires attention to the following points. The isononanoic acid should be stored in a cool, dry and well-ventilated warehouse, avoiding direct sunlight and high temperature environment. The storage container should be well sealed, usually using acid and alkali resistant plastic barrels or stainless steel barrels to prevent leakage and contamination. The isononanoic acid should be stored separately from the oxidant, strong acid, strong alkali and other chemicals to avoid chemical reaction. The storage area shall be equipped with leakage emergency treatment equipment to deal with possible leakage accidents.

Safety and Environmental Precautions

When handling and using isononanoic acid, it is necessary to strictly observe the safety procedures. Operators should wear protective gloves, goggles and protective clothing to avoid direct skin and eye contact with isononanoic acid. In case of accidental contact, rinse immediately with plenty of water and seek medical attention. When isononanoic acid leaks, it should be immediately absorbed with adsorption materials such as sand, sawdust, etc., and properly disposed. Discarded isononanoic acid and its packaging shall be treated in accordance with the national hazardous waste treatment regulations to avoid environmental pollution.

Conclusion

As an important chemical raw material, isononanoic acid has a wide range of industrial applications and good market prospects. Its unique chemical properties make it play an important role in the field of plasticizers, lubricant additives, surfactants and so on. With the development of technology and the change of market demand, the application field of isononanoic acid will continue to expand. In the process of production and use, attention should be paid to safety and environmental protection to achieve sustainable development.
