Properties of sec-butyl acetate

Sec-butyl acetate (sec-Butyl acetate) is an organic compound with the chemical formula C6H12O2. It is a colorless liquid with a sweet, fruity smell. It has a density of about 0.87g/cm³, a melting point of -99°C, a boiling point of about 112°C and a flash point of 18°C. The solubility of sec-butyl acetate in water is low, but it can be miscible with many organic solvents, such as ethanol, ether and acetone. Its vapor pressure is high, easy to volatilize at room temperature.

Use of sec-butyl acetate

Sec-butyl acetate has a wide range of uses in industry. It is often used as a solvent, especially in the coatings and paint industry, to dissolve resins, cellulose, synthetic rubber and a variety of paint ingredients. Due to its moderate volatilization rate, it can help the paint form a smooth coating. It is also used as a cleaning agent, ink thinner and binder component. In the fragrance and fragrance industry, sec-butyl acetate is also used as a fragrance additive due to its sweet smell.

Sec-butyl acetate upstream and downstream raw materials

The production of sec-butyl acetate requires two main feedstocks: acetic acid and sec-butanol (sec-Butanol). Acetic acid is typically produced by the oxidation of ethylene or the carbonylation of methanol. The secondary butanol can be obtained by the isomerization reaction of n-butanol, and can also be separated by the by-products of the petroleum cracking process. The reaction is usually carried out in the presence of an acidic catalyst, and sec-butyl acetate is produced by esterification.

The downstream products of sec-butyl acetate mainly include various coatings, paints, cleaning agents and fragrances. These products are widely used in construction, automobile manufacturing, electronic equipment and home decoration industries.

SECOND-BUTYL ACETATE STORAGE METHOD

Since sec-butyl acetate is a flammable liquid, its storage requires special attention to safety measures. It should be stored in a cool, dry, well-ventilated place, away from direct sunlight and high temperature environment. The storage container shall be a corrosion-resistant closed container to avoid leakage. The storage area should be far away from fire, heat and flammable materials, and equipped with corresponding fire fighting equipment.

During transportation, sec-butyl acetate should use special transportation tools, and the transportation container must meet relevant safety standards to ensure no leakage and damage. During transportation, severe vibration and collision shall be avoided, and care shall be taken to handle the container gently during loading and unloading to prevent the container from breaking.

SE-BUTYL ACETATE SAFETY AND ENVIRONMENTAL IMPACT

Sec-butyl acetate has certain toxicity, and inhalation of its vapor or skin contact may cause effects on human health. Short-term exposure to high concentrations of steam may cause headaches, nausea, eye and respiratory irritation, while long-term exposure may cause liver and kidney damage. Therefore, when using sec-butyl acetate, appropriate protective measures should be taken, such as wearing protective gloves, glasses and face masks, and maintaining good ventilation in the workplace.

In terms of environment, sec-butyl acetate has a certain risk of pollution to water bodies. If a large amount of leakage into water bodies, it may cause harm to aquatic organisms. Therefore, its discharge should be strictly controlled, and relevant environmental protection regulations should be followed when dealing with waste, and effective wastewater treatment measures should be taken to prevent environmental pollution.

Sec-Butyl Acetate Market Prospects

With the development of the global economy and the advancement of industrialization, the market demand for sec-butyl acetate is increasing year by year. Especially in developing countries, the rapid development of the construction, automotive and electronics industries has driven the demand for coatings and paint products, thereby driving the growth of the sec-butyl acetate market. The improvement of environmental awareness and the increasingly stringent regulations have also promoted the application of low toxicity and low volatility solvents. As a relatively environmentally friendly solvent, sec-butyl acetate has a good market prospect.

Conclusion

As an important industrial solvent, sec-butyl acetate has excellent chemical and physical properties, and is widely used in coatings, paints, cleaning agents and spices. Its production depends on the supply of raw materials for acetic acid and sec-butanol, while its storage and use require strict compliance with safety and environmental requirements. With the growth of market demand and the strengthening of environmental regulations, sec-butyl acetate has broad prospects for development in the future. Enterprises still need to pay attention to safety management and environmental protection in the process of production and use to achieve sustainable development.
