What is Bis(2-ethylhexyl) adipate?

Chemical properties

colourless oily liquid

The Uses of Bis(2-ethylhexyl) adipate

Bis(2-ethylhexyl) adipate also known as dioctyl adipate (DOA) can be used as a plasticizer for improving the impact properties of polymers. DOA is also used to produce clear films for food packaging applications and in synthetic rubber industries due to its compatibility with nitrocellulose and ethylcellulose.

The Uses of Bis(2-ethylhexyl) adipate

The compound is used as a plasticizer for flexible vinyl food wraps and as a solvent for aircraft lubricants.

The Uses of Bis(2-ethylhexyl) adipate

Plasticizer in polyvinyl chloride films, sheeting, extrusions, and plastisols; solvent and emollient in cosmetics

Definition

ChEBI: 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.

Production Methods

DEHA is manufactured by esterification of adipic acid and 2-ethylhexanol.

General Description

Colorless to straw-colored liquid with a mild odor. Floats on water.

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

Non flammable

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.
