Dioctyl sebacate (CH2)8(COOC8H17)2, or di(2-ethylhexyl) sebacate, is an organic compoundwhich is the diester of sebacic acid and 2-ethylhexanol. It is an oily colorless liquid,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.
