| Trioctyl trimellitate Usage And Synthesis |
| Chemical Properties | viscous yellow liquid |
| Usage | Trioctyl Trimellitate is a plasticizer that was evaluated for endocrine disrupting activities through estrogen receptor alpha binding assay. |
| General Description | Yellow oily liquid. |
| Air & Water Reactions | Insoluble in water. |
| Reactivity Profile | Trioctyl trimellitate 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. |
| Fire Hazard | Trioctyl trimellitate is probably combustible. |
