Bis(2-ethylhexyl) adipate is a colorless to straw-colored liquid with a mild odor. Floats on water. (USCG, 1999)|Bis(2-ethylhexyl) adipate is a diester resulting from the formal condensation of the carboxy groups of adipic acid with 2-ethylhexan-1-ol. It is used as a plasticiser in the preparation of various polymers. It has a role as a plasticiser. It is a diester, a carboxylic ester and a member of dicarboxylic acids and O-substituted derivatives. It derives from a 2-ethylhexan-1-ol and an adipic acid.

Bis(2-ethylhexyl) adipate Use and Manufacturing
Methods of Manufacturing
General procedure: A (nano)biocatalyst (10–200 mg/l mmol of dicarboxylic acid) wasintroduced into a 10 mL round-bottom flask. Next, decane (20 wt. percent peracid, internal standard), solvent (0–2 mL/L mmol of acid), dicarboxylicacid (1.0 mmol) and alcohol (2.0–32.8 mmol) were successively added.The reaction mixture was then inserted into the thermostatic shaker(250 rpm) at 25–45 °C and the reaction was carried out for 2–24 h.During the reaction, 10 μl of the samples (diluted with acetonitrile)were periodically collected to monitor the reaction progress by GC-FID.After the completion of the reaction, the (nano)biocatalyst was filteredand washed with 20 mL of cyclohexane. The filtrate was concentratedusing a rotary evaporator (7 mbar, 110 °C, 6 h for di-n-butyl esters and5 mbar, 135 °C, 8 h for 2-ethylhexanol esters) to remove cyclohexaneand alcohols. The esters were purified by column chromatographyusing Al2O3 as the stationary phase and CH2Cl2 as the eluent. NMRspectra are available in Supplementary Information (Figs S9-S24).
It is derived from adipic acid and 2-ethylhexanol under the catalysis of sulfuric acid under reduced pressure. The content of industrial product di(2-ethylhexyl) adipate ≥99%. Raw material consumption (kg/t) adipic acid 4152-ethylhexanol 750
