ECHEMI Editorial Reference

The empirical formula of diisooctyl phthalate (DIOP) is C24H38O4. The structural formula of DIOP varies because the iso-alcohols used in the manufacture contain several isomers. DIOP is insoluble in water, but it is soluble in organic solvents.
Di-isooctyl phthalate is an oily colorless liquid with a slight ester odor. Denser than water. Insoluble in water. (USCG, 1999)|Liquid|COLOURLESS VISCOUS LIQUID.
Di-isooctyl phthalate is an oily colorless liquid with a slight ester odor. Denser than water. Insoluble in water. (USCG, 1999)|Diisooctyl phthalate is a phthalate ester and a diester.

Reactive Group:

Esters, Sulfate Esters, Phosphate Esters, Thiophosphate Esters, and Borate Esters

Reactivity Profile:

DI-ISOOCTYL PHTHALATE reacts exothermically with acids to generate isooctyl alcohol and phthalic acid. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by interaction with caustic solutions. Flammable hydrogen is generated by mixing with alkali metals and hydrides. Can generate electrostatic charges. [Handling Chemicals Safely, 1980. p. 250].

Autoignition Temperature:

393 °C
