[Chemical Knowledge]：The nature, use, upstream and downstream raw materials, storage methods, the density of isobutyl acetate is what.

Properties of isobutyl acetate

Isobutyl acetate (Isobutyl acetate) is a colorless and transparent liquid with a sweet, fruity odor. Its chemical formula is C6H12O2 and its molecular weight is 116.16g/mol. Isobutyl acetate has low solubility in water, but is miscible with most organic solvents. It has a boiling point of 118°C, a flash point of 18°C and a density of 0.87g/cm³. Its high vapor pressure makes it volatile at room temperature, which makes it unique in many applications.

Use of isobutyl acetate

Isobutyl acetate is widely used in coatings, inks, adhesives and cleaners. Its good dissolution properties and rapid volatility make it an ideal solvent, especially in the coatings industry for the dissolution of nitrocellulose, polyurethane and alkyd resins. Isobutyl acetate is also widely used in the food and cosmetics industries as an additive to spices and flavors to give products a fruity aroma. It is also widely used in the pharmaceutical industry and is often used as a solvent for some pharmaceutical preparations.

Isobutyl acetate upstream feedstock

The production of isobutyl acetate is mainly achieved by the esterification reaction of acetic acid and isobutanol. Upstream feedstocks include acetic acid (acetic acid) and isobutanol, both of which are important basic chemical feedstocks in the chemical industry. Acetic acid can be produced by methanol carbonylation or ethylene oxidation, while isobutanol is usually produced by isobutylene hydration. The catalyst plays an important role in the esterification reaction, and the commonly used catalysts are concentrated sulfuric acid, p-toluenesulfonic acid and so on.

Isobutyl acetate downstream products

Isobutyl acetate is an intermediate or additive for a variety of products, and its downstream products include various coatings, detergents, fragrances and pharmaceuticals. Because of its good solubility and volatility, isobutyl acetate is widely used in the production of high-performance coatings and inks. These products have a wide range of applications in the construction, automotive, electronics and other industries. In household chemicals, isobutyl acetate is used as a blending ingredient for fragrances and flavors, giving the product a fresh and pleasant aroma.

Isobutyl acetate storage method

Isobutyl acetate is highly flammable and its storage must follow strict safety regulations. The storage environment should be well ventilated and protected from direct sunlight and high temperatures. Isobutyl acetate should be stored in a sealed container, away from fire and heat sources, and avoid contact with oxidants, acids and bases. The storage area shall be equipped with appropriate fire fighting equipment to deal with possible fire accidents. When handling isobutyl acetate, operators should wear protective gloves and goggles to avoid skin and eye contact.

Isobutyl acetate safety and environmental protection

Although isobutyl acetate has some toxicity, its toxicity is relatively low. During use and operation, inhalation of high concentrations of isobutyl acetate vapor may cause symptoms such as headache, dizziness and difficulty breathing. Therefore, the workplace should maintain good ventilation and use appropriate personal protective equipment. For environmental protection, isobutyl acetate can be biodegraded in nature, but when dealing with waste, it is still necessary to follow environmental regulations to avoid polluting water and soil.

market prospect analysis

With the continuous development of coatings, inks and adhesives, the demand for high-performance solvents continues to grow, and the market demand for isobutyl acetate is also steadily increasing. Especially in the Asia-Pacific and North American markets, the rapid development of the construction and automotive industries has brought a broad market space for isobutyl acetate. With the increasingly stringent environmental regulations, low toxicity and easy degradation solvent products are gradually favored, and isobutyl acetate has a good market prospect in this trend.

Conclusion

As an important organic chemical raw material, isobutyl acetate has unique physical and chemical properties and broad application prospects. Its upstream raw material sources are rich, downstream products are widely used, and market demand is growing steadily. In order to ensure its safe use and storage, the relevant safety regulations and environmental protection requirements must be strictly observed. In the future, with the increasing demand for high-performance and low-toxicity solvents in various industries, isobutyl acetate is expected to be widely used in more fields, and the market prospect is promising.
