Description
Bis(2-ethylhexyl) adipate, also known as dioctyl adipate (DOA), is a colorless to straw-colored oily liquid with a mild odor. It is a diester resulting from the formal condensation of the carboxy groups of adipic acid with 2-ethylhexan-1-ol. Bis(2-ethylhexyl) adipate is characterized by its ability to float on water and is commonly used as a plasticizer in various applications.
Uses
Used in Plastic Industry:
Bis(2-ethylhexyl) adipate is used as a plasticizer for improving the impact properties of polymers. It is particularly effective in polyvinyl chloride films, sheeting, extrusions, and plastisols, enhancing the flexibility and durability of these materials.
Used in Food Packaging Industry:
DOA is utilized in the production of clear films for food packaging applications. Its compatibility with materials like nitrocellulose and ethylcellulose makes it a suitable choice for creating transparent and flexible packaging that preserves the quality of the packaged food.
Used in Cosmetics Industry:
In the cosmetics industry, Bis(2-ethylhexyl) adipate serves as a solvent and emollient. Its ability to dissolve other ingredients and provide a smooth, moisturizing texture makes it a valuable component in various cosmetic products.
Used in Aircraft Lubricants:
Bis(2-ethylhexyl) adipate is also used as a solvent for aircraft lubricants. Its properties allow it to effectively dissolve and carry the lubricating components, ensuring the proper functioning and maintenance of aircraft machinery.
Production Methods
DEHA is manufactured by esterification of adipic acid and
2-ethylhexanol.
Air & Water Reactions
Bis(2-ethylhexyl) adipate slowly hydrolyzes. Insoluble in water.
Reactivity Profile
Bis(2-ethylhexyl) adipate is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Can generate electrostatic charges. [Handling Chemicals Safely 1980. p. 250]. Bis(2-ethylhexyl) adipate is incompatible with oxidizing materials and water. Bis(2-ethylhexyl) adipate is also incompatible with nitrates.
Health Hazard
Liquid may cause mild eye irritation. Repeated or prolonged skin contact may cause irritation.
Fire Hazard
Behavior in Fire: Use water spray to cool exposed containers.
Flammability and Explosibility
Nonflammable
Safety Profile
Moderately toxic by intravenous route. Mildly toxic by ingestion. Experimental reproductive effects. Mutation data reported. An eye and skin irritant. Questionable carcinogen with experimental carcinogenic data. See also ESTERS. When heated to decomposition it emits acrid smoke and irritating fumes.
Check Digit Verification of cas no
The CAS Registry Mumber 103-23-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 103-23:
(5*1)+(4*0)+(3*3)+(2*2)+(1*3)=21
21 % 10 = 1
So 103-23-1 is a valid CAS Registry Number.

Nano-SO42-/TiO2catalyzed eco-friendly esterification of dicarboxylic acids
Ji, Xianbing,Chen, Yinxia,Shen, Zuoyuan
, p. 5769 - 5772 (2014)
Nano-SO42-/TiO2 was prepared by wet impregnation method. The structure and properties of the prepared nano-SO42-/TiO2catalyst was characterized by XRD, SEM, TEM and BET analysis. The catalytic activities of the catalysts were tested by the esterification of sebacic acid with 2-ethyl hexanol and a series of other dicarboxylic acid. The influence factors on the reaction, such as the catalyst calcination temperature, reaction temperature/time and the molar ratio of acid to alcohol were extensively explored. Nano-SO42-/TiO2prepared exhibited much higher catalytic activity in esterification reactions. By applying the optimized reaction condition, i.e. 160 C, 2 h, 5 wt % nano-SO42-/TiO2with a 1:3 molar ratio of sebacic acid to 2-ethyl hexanol, higher than 99 % isolated of the desired ester could be obtained.
Micro-flow nanocatalysis: synergic effect of TfOH@SPIONs and micro-flow technology as an efficient and robust catalytic system for the synthesis of plasticizers

, p. 37835 - 37840 (2018)
The combination of continuous flow technology with immobilizing of only 0.13?mol% of triflic acid (TfOH) on silica-encapsulated superparamagnetic iron oxide nanoparticles (SPIONs) under solvent-free conditions successfully provided a powerful, efficient, and eco-friendly route for the synthesis of plasticizers. The turnover frequency value in micro-flow conditions varied in the range of 948.7 to 7384.6 h?1 compared to 403.8 to 3099 h?1 for in-flask. This technique works efficiently, encouraging future applications of micro-flow nano-catalysis in green chemistry.
