Dipropyl Adipate Introduction:
Dipropyl Adipate (DPA for short) is an organic compound synthesized by esterification of adipic acid and n-propanol. Its molecular formula is C12H22O4. It is a colorless and transparent liquid at room temperature with low viscosity, high boiling point (about 250°C) and excellent solubility. As a typical aliphatic dibasic acid ester, its molecular structure contains two propoxy groups, which makes it have good compatibility in both polar and non-polar solvents.
In terms of synthesis process, the industrial preparation of Dipropyl Adipate usually adopts acid-catalyzed esterification. Concentrated sulfuric acid or solid acid catalysts are used to accelerate the reaction process, and the product is purified through vacuum distillation. Eventually, industrial-grade products with a purity higher than 99% are obtained. According to industry standards (such as ASTM D-1045), its acid value needs to be controlled below 0.1 mg KOH/g and the moisture content is less than 0.05% to meet the strict requirements for stability in downstream applications.
In terms of physical properties, the density of Dipropyl Adipate is slightly greater than that of air, which affects its floating and sinking characteristics when mixed with other gases. Its solubility is also rather unique. It can dissolve in most organic solvents such as ethanol and ether, and is also compatible with some specific polymer systems, which provides a basis for its application in different material fields.
Dipropyl Adipate shares many characteristics with ester compounds and, when exposed to acidic or alkaline conditions, can undergo hydrolysis reactions which produce acids and alcohols as by-products of hydrolysis reactions. This property of Dipropyl Adipate makes its hydrolysis reaction particularly significant when applied in various chemical processes and environmental degradation processes, such as film formation processes that utilize coatings; its hydrolysis may have an impactful influence on performance and durability of coatings formed with its use.
During storage and transportation, Dipropyl Adipat should avoid contact with strong oxidants and keep the container sealed to prevent moisture absorption. Its chemical stability is excellent at room temperature, but slight hydrolysis may occur when exposed to ultraviolet or high temperature environments for a long time. Therefore, it is recommended to add antioxidants to extend the storage period. From a global supply chain perspective, the main manufacturers of this product are concentrated in China, Germany, and the United States, with an annual production capacity of over 100000 tons. The market size is showing a stable growth trend with the tightening of environmental policies.

The Application Situation Of Dipropyl Adipate
Dipropyl Adipate has extremely wide applications in the field of chemical engineering. In terms of solvents, it is an excellent organic solvent that can dissolve a variety of resins and polymers. For instance, in the coatings industry, it can be used to formulate special coating formulas, endowing the coatings with better leveling, adhesion and drying performance. Compared with traditional solvents, Dipropyl Adipate can enable the coating to form a more uniform layer during the construction process, reduce brush marks and particles, thereby improving the coating quality. In some high-performance coatings such as automotive paint and industrial anti-corrosion paint, its unique solubility helps to fully exert the protective and decorative functions of the coatings.
Dipropyl Adipate can be utilized in the plastics industry as a plasticizer, providing plastic products with greater flexibility and cold resistance, lessening their susceptibility to brittle cracking in low temperature environments. Its application may lead to significant gains in processing performance as well as physical properties of finished product. Comparative to other plasticizers, low migration plasticizers possess the advantage of not easily volatilizing or precipitating from plastics during long-term use, thus protecting its performance.
For the spice industry, Dipropyl Adipat is one of the important spice ingredients. Its unique fruit flavor makes it have unique value in blending fruit essence and daily essence. In the field of food spices, it can be used to enhance the aroma of candies, beverages, baked goods, etc., adding tempting fruit flavors to products. In terms of daily perfumes, such as perfume, cosmetics and detergents, Dipropyl Adipate can cooperate with other perfumes to create rich and lasting fragrance. In addition, its stability in spices and good compatibility with other spice components make it highly flexible in spice formulations.
Dipropyl Adipate also has certain application potential in the pharmaceutical field. It can be used as a solvent or excipient in pharmaceutical preparations for the preparation of liquid preparations and ointments. For example, in the extraction and purification process of certain drugs, Dipropyl Adipate can be used as a solvent to help dissolve the active ingredients, facilitating subsequent separation and purification operations. In drug delivery systems, it may help improve the solubility and bioavailability of drugs, thereby enhancing the efficacy of drugs. However, in pharmaceutical applications, due to the involvement of human health and safety, there are extremely high requirements for its purity and safety, so strict quality control and supervision are required.
The Advantages Of Dipropyl Adipate
Compared with traditional plasticizers, the core advantage of Dipropyl Adipate lies in its combination of environmental protection and versatility. From the perspective of molecular design, it does not contain a benzene ring structure, which fundamentally avoids the reproductive toxicity and environmental hormone risks of phthalates, and is in line with the global trend of upgrading chemical regulation (such as the EU SVHC list and the US TSCA Act).
In terms of technical performance, Dipropyl Adipate’s wide temperature range adaptability is particularly prominent. It can maintain a stable plasticizing efficiency in the range of -30°C to 150°C, which makes it irreplaceable in extreme temperature scenarios such as automotive interiors and outdoor cable sheaths. In terms of compatibility with polymer materials, its solubility parameter (about 18.5 MPa¹/²) is highly matched with most polar resins, so it can be evenly dispersed without the need to add additional compatibilizers during blending, simplifying the production process and reducing the overall cost.
From an economic perspective, although the unit cost of this compound is slightly higher than that of traditional products such as DOP, its low loss rate (migration loss less than 0.5%) during processing and long product life characteristics can significantly reduce the cost of the entire life cycle. Taking plastic products as an example, the service life of PVC hoses with Dipropyl Adipate can be extended by more than 30%, while reducing the surface contamination caused by plasticizer precipitation. This long-term effect is particularly important in the fields of medical consumables and children’s toys, which directly enhances the market competitiveness of end products.
In terms of sustainable development, the biodegradability of Dipropyl Adipate (28-day degradation rate>60%) is significantly better than that of petroleum-based plasticizers, which meets the requirements of the circular economy for material recyclability. Its synthetic raw material adipic acid can be prepared by biofermentation, further reducing dependence on fossil resources. From the perspective of industrial chain synergy, the coordinated development of this compound and bio-based plastics (such as PHA and PBS) is forming a new technology closed loop, providing solutions that meet the carbon neutrality goals for industries such as packaging and agricultural films.
Considering the technical parameters and market demand, the competitive advantage of Dipropyl Adipate is also reflected in the continuous expansion of its application boundaries. In the field of new energy, its potential as a coating agent for lithium-ion battery separators is being explored, and battery safety can be improved by improving the electrolyte affinity and thermal stability of the separator. In electronic packaging materials, its low dielectric constant characteristics (ε≈3.2) help reduce signal transmission losses and meet the special requirements of 5G communication equipment for polymer materials. This cross-industry applicability makes it a rare platform product in the field of fine chemicals, with broad space for technological iteration.
