Dioctyl sebacate(Cas 122-62-3) Usage
|
Description |
Dioctyl sebacate (DOS) is an organic compound serving as a plasticizer, commonly used for its colorless or light yellow, viscous liquid form with a distinct odor. It possesses low volatility, high plasticizing efficiency, and electrical insulation properties. Primarily utilized in vacuum pumps, DOS is a clear pale yellow liquid that is insoluble in water. Produced by esterifying 2-ethylhexanol with sebacic acid in the presence of an acid catalyst, it is a stable and non-flammable substance. While not classified as flammable or explosive, DOS may react with acids, oxidizing materials, and hydrolyze under acidic or basic conditions. |
|
Uses |
In vacuum pumps. |
|
Production Methods |
Di(2-ethylhexyl) sebacate is manufactured by esterifying 2-ethylhexanol with sebacic acid in the presence of an acid catalyst. |
|
Air & Water Reactions |
Insoluble in water. |
|
Reactivity Profile |
Dioctyl sebacate 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. Dioctyl sebacate can react with oxidizing materials. Dioctyl sebacate will hydrolyze under acidic or basic conditions. |
|
Fire Hazard |
Dioctyl sebacate is probably combustible. |

Coating Mass Dependence of Soot Aggregate Restructuring due to Coatings of Oleic Acid and Dioctyl Sebacate
R. Ghazi &J. S. Olfert
, Aerosol Science and Technology Volume 47, 2013 - Issue 2
The effect of the mass of coating on the morphology of soot particles was studied using oleic acid and dioctyl sebacate (DOS) coatings. A wide range of coatings were used, with up to 10 times as much coating as the mass of the soot.
