| Trioctyl trimellitate Usage And Synthesis |
| Chemical Properties | TRIOCTYL TRIMELLITATE is viscous yellow liquid |
| Uses | TRIOCTYL TRIMELLITATE is a plasticizer that was evaluated for endocrine disrupting activities through estrogen receptor alpha binding assay. |
| Uses | TOTM has been used as reference fluid for viscosity measurements using vibrating wire viscometer, to evaluate its use as a lubricant in the polymer industry. |
| Production Methods | TOTM is manufactured by acid-catalyzed esterification of trimellitic anhydride and 2-ethylhexanol. |
| 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. |
| Flammability and Explosibility | Nonflammable |
| Safety Profile | Very low toxicity by ingestion.When heated to decomposition it emits acrid smoke andirritating vapors. |
