Diisooctyl phthalate Usage And Synthesis
  • Chemical PropertiesThe 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.
  • UsesIts major use is as a plasticizer.
  • Production MethodsDIOP is manufactured by the reaction of phthalic anhydride with isooctanol in the presence of an acid catalyst.
  • General DescriptionOily colorless liquid with a slight ester odor. Denser than water. Insoluble in water.
  • Air & Water ReactionsInsoluble in water.
  • Reactivity ProfileDiisooctyl 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 HazardProduces no ill effects at normal temperatures but may give off irritating vapor at high temperature.
  • Fire HazardSpecial Hazards of Combustion Products: None
