[Chemical Knowledge]：The nature, use, upstream and downstream raw materials, storage methods, the latest price of sec-butyl ester.

Properties of sec-butyl ester

Sec-butyl ester (sec-Butyl acetate) is a colorless transparent liquid with a fruity aroma. Its molecular formula is C6H12O2, its molecular weight is 116.16g/mol, its boiling point is between 112-114°C, and its density is 0.875g/cm³. Sec-butyl ester is soluble in ethanol, ether and other organic solvents, but insoluble in water. These physicochemical properties give it unique advantages in solvent applications. The vapor pressure of sec-butyl ester is low and the flash point is 19°C, so it is necessary to pay attention to fire and explosion prevention measures during use.

sec-butyl ester use

Sec-butyl ester has a wide range of uses in industry, mainly used in coatings, paints, resins, inks and other industries. Because of its good solubility and moderate volatilization rate, sec-butyl ester is often used as a solvent in paints and coatings, which can effectively improve the construction performance and surface quality of the product. Sec-butyl esters are also used in the preparation of resins and adhesives to improve the solubility and fluidity of these materials. In the printing industry, sec-butyl ester as an ink solvent can improve the leveling and drying speed of the ink and improve the printing effect.

Sec-butyl ester upstream and downstream raw materials

The production of sec-butyl ester usually adopts esterification reaction, and the main raw materials are sec-butanol (sec-Butanol) and acetic acid (acetic acid). In the reaction process, sec-butyl alcohol and acetic acid react under the action of catalyst to produce sec-butyl ester and water. Commonly used catalysts include sulfuric acid, phosphoric acid, solid acids, and the like. Reaction conditions such as temperature, pressure and reaction time have an important influence on the yield and quality of the product. The upstream feedstock, sec-butanol, can be produced by the hydration of isobutylene (isobutylene), while acetic acid is usually produced by methanol carbonylation or ethylene oxidation.

Sec-butyl ester storage method

Because sec-butyl ester is flammable and volatile, its storage requires special attention to fire and explosion prevention. Sec-butyl ester should be stored in a cool, dry, well-ventilated warehouse, away from fire and heat sources, and avoid direct sunlight. Storage containers shall be well sealed to prevent leakage and evaporation. The storage environment temperature of sec-butyl ester should be controlled at room temperature to avoid pressure increase caused by excessive temperature. The storage area shall be equipped with appropriate fire fighting equipment, such as dry powder fire extinguishers or carbon dioxide fire extinguishers, to deal with sudden fire situations.

SECONDY BUTYL EFFICACY SAFETY AND ENVIRONMENTAL PROBLEMS

Sec-butyl ester has certain toxicity to the human body, mainly through the respiratory tract and skin into the body. Prolonged exposure may cause symptoms such as headache, dizziness, and nausea. It is irritating to the skin and may cause dry skin and cracks. Therefore, when using and handling sec-butyl esters, wear appropriate protective equipment, such as protective gloves and goggles, to avoid direct contact and inhalation of its vapors. Sec-butyl ester has a certain degree of volatility and biodegradability in the environment, but its vapor has a polluting effect on the atmosphere. In the treatment of waste sec-butyl ester, local environmental protection regulations should be followed and effective waste gas treatment measures should be taken to prevent environmental pollution.

Market outlook and trend analysis

With the advancement of industrialization and urbanization, the demand for sec-butyl ester in downstream industries such as coatings and paints continues to grow, and the market prospects are broad. The improvement of environmental awareness and the increasingly strict regulations have also promoted the improvement of sec-butyl production technology, and promoted the development of enterprises in the direction of green and low pollution. In the future, the market demand for sec-butyl ester will be further expanded, especially in high-performance environmentally friendly coatings and new resin materials. Production enterprises of sec-butyl ester should pay attention to market dynamics and actively develop new products and processes to enhance market competitiveness.

Conclusion

As an important chemical product, sec-butyl ester has great market demand because of its excellent solvent performance and wide application fields. Its production involves upstream raw materials such as sec-butanol and acetic acid, and safety protection and environmental protection measures should be paid attention to during storage and use. In the future, with the progress of technology and the growth of market demand, the sec-butyl industry will usher in a broader space for development. In this process, enterprises should pay attention to technological innovation and environmental protection investment, so as to adapt to market changes and regulatory requirements, and enhance the added value and competitiveness of products.
