Diethyl adipate, with the CAS number 141 - 28 - 6, is a colorless to slightly yellowish liquid. It has a molecular formula of C₁₀H₁₈O₄ and a molecular weight of 202.25 g/mol. The product is known for its high quality and comes at a very competitive price in the market. It has a melting point of - 19 °C and a boiling point of approximately 251 - 252 °C. Diethyl adipate has a density of about 0.966 g/cm³ at 20 °C. It is relatively soluble in organic solvents such as ethanol, ether, and chloroform, but has limited solubility in water.
Diethyl adipate has a wide range of applications in different industries. In the fragrance industry, it is used as a solvent and a fixative. Its mild and pleasant odor makes it suitable for blending with other fragrance materials, enhancing the longevity and stability of perfumes and colognes. In the plastic industry, it serves as a plasticizer. When added to plastics, it increases their flexibility, durability, and workability. This makes the plastics easier to mold and shape during the manufacturing process, and also improves their performance in various environments. Additionally, it can be used as an intermediate in the synthesis of other organic compounds in the chemical industry.
When using Diethyl adipate in the fragrance industry, it should be added in the appropriate proportion according to the formulation of the perfume. Usually, it is mixed with other fragrance ingredients in a suitable container under controlled temperature and stirring conditions. In the plastic industry, it is incorporated into the plastic resin during the compounding process. The amount of Diethyl adipate added depends on the desired properties of the final plastic product. It is important to ensure thorough mixing to achieve uniform distribution within the plastic matrix. When handling Diethyl adipate, proper safety measures should be taken. Wear appropriate protective clothing, gloves, and goggles to avoid direct contact with the skin and eyes. Work in a well - ventilated area to prevent inhalation of vapors.
Case 1: Fragrance Manufacturing
A perfume company was developing a new line of high - end perfumes. They used Diethyl adipate as a key solvent and fixative. By adding 10% Diethyl adipate to their fragrance formulation, they found that the perfume had a more stable and long - lasting scent. Customers reported that the perfume lasted on their skin for up to 8 hours, compared to only 4 - 5 hours for similar perfumes without Diethyl adipate.
Case 2: Plastic Production
A plastic manufacturing company was producing flexible PVC pipes. They added Diethyl adipate as a plasticizer at a ratio of 5% to the PVC resin. The resulting pipes were more flexible and easier to bend during installation. The pipes also showed better resistance to cracking and brittleness, even in cold environments. This led to a significant reduction in product returns due to quality issues.
