[Chemical Knowledge]：Properties, uses, upstream and downstream raw materials, storage methods, and the role of wax esters

Properties of Butyl Cwax

Butyl cerate, chemical name is butyl butyrate (Butyl Butyrate), molecular formula is C8H16O2, molecular weight is 144.21g/mol. It is a colorless to light yellow liquid with fruity aromas, especially those of apple and pineapple, so it is widely used in the fragrance industry. Butyl cerylate has a boiling point of about 165°C and a flash point of 49°C, with a certain volatility. It has a density of 0.878g/cm³ and is slightly soluble in water, but miscible with ethanol, ether and other organic solvents.

Application of butyl cerate

Due to its unique flavor and relatively low toxicity, butyl cerylate is widely used in food, beverage and flavor industries. It is an important ingredient in the manufacture of artificial flavors and is often used to impart fruit aromas. In addition to the fragrance industry, butyl cerate also has applications in cosmetics, cosmetic products, such as perfumes, shampoos and skin care products. Butyl cerate is also used as a solvent to adjust viscosity and improve fluidity in the fields of paints, coatings and resins.

Upstream raw materials

The production of butyl cerate is mainly realized by esterification reaction, and the upstream raw materials include n-butanol and n-butyric acid. n-Butanol is an important organic chemical raw material, which can be produced by hydrogenation of propylene or hydrogenation reduction of acetaldehyde. Butyric acid can be obtained by oxidation of butene or microbial fermentation. In industrial production, n-butanol and n-butyric acid are esterified under the action of acid catalyst to produce butyl cerate and water.

Downstream Products

As an important intermediate, butyl cerate can be further processed to produce various fine chemical products. For example, butyl cerylate can be reduced by hydrogenation to yield 1-butanol and 1-butyric acid, which are used to make other esters and solvents. It can also be used as a highly efficient solvent in the production of downstream products such as resins, coatings and adhesives.

storage method

The storage of butyl cerylate requires consideration of its chemical properties and safety. Butyl cerate should be stored in a cool, dry, well-ventilated warehouse, away from direct sunlight and high temperature environment. Storage containers should be well sealed, usually stainless steel or aluminum containers, because butyl cerate has a slight swelling effect on certain plastics and rubbers. The storage environment should be kept away from fire and heat sources to prevent the accumulation of static electricity from causing fire. Since butyl cerylate has a certain volatility, it should be avoided to open the container for a long time to reduce evaporation loss.

Safety measures

Necessary safety measures should be taken when handling and using butyl cerate. Wear protective gloves, goggles and protective clothing to prevent skin and eye contact. The workplace should be well ventilated and local exhaust equipment should be used if necessary. Avoid inhaling its vapor. Prolonged exposure to high concentrations of butyl cerate may cause headache, dizziness, nausea and other symptoms. In the event of a leak, the leak area should be quickly isolated and treated with adsorbent materials to prevent the spread of contamination.

Market Prospects

With the continuous development of flavors and fragrances, food and beverage and cosmetics industries, the market demand for butyl cerate is growing steadily. Especially in the Asia-Pacific region, with the economic development and the improvement of living standards, the demand for high quality fragrances and cosmetics has increased, which has led to the expansion of the butyl cerate market. In the future, the trend of green chemical industry and sustainable development will promote the production process of butyl cerylate to be more environmentally friendly and efficient.

Technical Development

In the production technology of butyl cerate, researchers continue to explore more efficient and environmentally friendly synthesis methods. For example, the use of a solid acid catalyst instead of a conventional liquid acid catalyst not only improves the reaction efficiency, but also reduces the generation of by-products and reduces environmental pollution. The application of biocatalytic method is also gradually promoted, and the synthesis of butyl wax acid ester by biological enzyme catalysis has the advantages of mild reaction conditions, high selectivity and environmental protection.

Conclusion

As an important organic chemical product, butyl cerate has a unique aroma and a wide range of applications. Its production involves upstream raw materials such as n-butanol and n-butyric acid, which are mainly used in the food, spice and daily chemical industries. In order to ensure its safe and effective use, appropriate storage and security measures need to be taken. In the future, with the progress of technology and the growth of market demand, the production and application of butyl cerylate have broad prospects.
