[Chemical Knowledge]：Properties, uses, upstream and downstream raw materials, storage methods, preparation mechanism of tert-butyl acetate

Properties of tert-butyl acetate

Tertiary butyl acetate (Tert-butyl acetate, TBAc for short) is an organic compound with the chemical formula C6H12O2. It is a colorless and transparent liquid at room temperature with a fruity odor. TBAc has a boiling point of 98°C, a flash point of 16°C, a density of 0.86g/cm³, a high vapor pressure, and is volatile. The solubility in water is low, but it has good miscibility with most organic solvents such as ethanol, ether, benzene, etc. Its chemical properties are stable and it is not easy to react under normal conditions, but it may decompose under high temperature or open flame conditions to produce toxic gases.

Application of tert-butyl acetate

Because of its good solubility and low toxicity, tert-butyl acetate is widely used in many fields. It is often used as a solvent for paints, paints, and varnishes, especially in areas with strict restrictions on volatile organic compounds (VOCs). Due to its lower toxicity and volatility, it is also used as an ingredient in cosmetics and perfumes. In industry, TBAc can be used as an intermediate in organic synthesis for the synthesis of other compounds, such as pharmaceutical intermediates, pesticides, dyes and so on. It can also be used in the electronics industry as a cleaning agent to remove residues from electronic components.

Upstream Feedstock Analysis

The main raw materials for the production of tert-butyl acetate include acetic acid and tert-butyl alcohol. Acetic acid is a basic chemical raw material, which can be produced by oxidation of acetaldehyde or carbonylation of methanol. The supply of acetic acid is relatively sufficient, the price is stable, and it is a low-cost raw material. Tert-butanol is then usually prepared by the isobutene hydration process or the isobutene peroxide process. Isobutene can be obtained by cracking petroleum or natural gas and is an important product of the petrochemical industry. The supply and price of tertiary butyl alcohol will be affected by the oil market, but overall supply and demand are balanced.

Downstream Product Analysis

As an important organic solvent and intermediate, tert-butyl acetate has a wide range of downstream products. Coatings and paints are its largest consumption areas. With the development of the construction and automotive industries, the demand for high-performance coatings is increasing, which promotes the market demand of TBAc. As people pay more attention to environmental protection and health, the demand for low toxicity and low volatility solvents increases, which makes the application of TBAc in cosmetics and electronic cleaning agents also grow. The market demand for pharmaceutical and pesticide intermediates has also steadily increased, further expanding the scope of application of TBAc.

STORAGE METHOD OF TERT-BUTYL ACETATE

Since tert-butyl acetate is flammable and volatile, its storage requires special attention. It should be stored in a cool, ventilated and dry warehouse, away from fire and heat sources, and avoid direct sunlight. The storage area shall be equipped with suitable fire extinguishing equipment, such as dry powder fire extinguishers, carbon dioxide fire extinguishers, etc. The container must be sealed to prevent leakage and moisture absorption. For large-scale storage, explosion-proof electrical and ventilation equipment should be used, and regular inspection and maintenance should be required. Operators should wear protective equipment to avoid direct contact to prevent health risks from inhalation or skin contact.

Market Analysis and Prospects

In recent years, the global demand for environmentally friendly solvents has been increasing, and tert-butyl acetate has occupied an important position in the market due to its low toxicity and excellent solubility. Especially in developed countries such as Europe and the United States, strict restrictions on VOCs emissions have promoted the growth of TBAc applications in the coatings and paint industries. With the development of the electronics industry and personal care products market, the application of TBAc in cleaning agents and cosmetics is also expanding. It is expected that the market demand for tert-butyl acetate will maintain steady growth in the next few years, especially in emerging market countries. With the advancement of industrialization, the demand for high-performance solvents will further increase.

Environmental and Safety Regulations

With the increasingly stringent environmental regulations, countries have put forward higher requirements for the use and discharge of chemicals. As a low toxicity and low volatility solvent, tert-butyl acetate has obvious advantages in this context. Its flammable and explosive nature also poses storage and transportation challenges. Enterprises must strictly abide by relevant laws and regulations in the process of production, storage and transportation to ensure safe production and environmental protection standards. In the future, with the further strengthening of environmental protection and safety regulations, the production and use of TBAc will face more regulatory and technical requirements, but it will also promote the improvement of technology and management of enterprises.

Conclusion

Tert-butyl acetate is an important organic compound, which plays an important role in many industries because of its unique properties and wide range of uses. Although its production and use face certain safety and environmental challenges, with the advancement of technology and the improvement of regulations, the market prospect of TBAc is still broad. For companies, improving production processes, optimizing storage and transportation management, and actively responding to environmental and safety regulations are key to ensuring their sustainable development. Overall, the position of tert-butyl acetate in the future chemical market will be further consolidated, and its application fields will continue to expand.
