Di (2-ethylhexyl) sebacate is manufactured by esterifying 2-ethylhexanol with sebacic acid in the presence of an acid catalyst. General Description Clear pale yellow liquid with a mild odor. Insoluble in water. Air & Water Reactions Insoluble in water. Reactivity Profile Dioctyl sebacate is an ester.

Infobox references. Dioctyl sebacate (also di (2-ethylhexyl) sebacate, commonly abbreviated as DOS, DEHS, and BEHS) is an organic compound which is the diester of sebacic acid and 2-ethylhexanol . It is an oily colorless liquid and is used as a plasticizer, including in the explosive C4. [3]

Application. Dioctyl Sebacate (DOS) is used as a plasticizer for PVC, nitrocelluloses, styrene resins, and synthetic rubbers where low temperature performance is required. DOS is also compliant with FDA CFR 21 for food contact materials. Dioctyl Sebacate can also be used in lubricants to allow more mobility at lower temperatures.

Impact on Dioctyl Sebacate Plasticizer. One of the products derived from sebacic acid that was heavily affected by the force majeure is the widely used plasticizer, DOS. DOS, an odorless and colorless liquid with low viscosity, is generated by reacting sebacic acid with 2-ethyl hexanol. DOS is food contact compliant according to FDA CFR 21.
