Diisooctyl phthalate Usage And Synthesis
| Chemical Properties | The empirical formula of diisooctyl phthalate (DIOP) isC24H38O4. The structural formula of DIOP varies becausethe iso-alcohols used in the manufacture contain severalisomers. DIOP is insoluble in water, butit is soluble in organic solvents. |
| Uses | Its majoruse is as a plasticizer. |
| Uses | Diisooctyl Phthalate can be used as a plasticizer. |
| Definition | ChEBI: Diisooctyl phthalate is a phthalate ester and a diester. |
| Production Methods | DIOP is manufactured by the reaction of phthalic anhydridewith isooctanol in the presence of an acid catalyst. |
| General Description | Oily colorless liquid with a slight ester odor. Denser than water. Insoluble in water. |
| Air & Water Reactions | Insoluble in water. |
| Reactivity Profile | Diisooctyl 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]. |
| Health Hazard | Produces no ill effects at normal temperatures but may give off irritating vapor at high temperature. |
| Fire Hazard | Special Hazards of Combustion Products: None |
