Trioctyl trimellitate Usage And Synthesis
Chemical PropertiesTRIOCTYL TRIMELLITATE is viscous yellow liquid
UsesTOTM has been used as reference fluid for viscosity measurements using vibrating wire viscometer, to evaluate its use as a lubricant in the polymer industry.
UsesTRIOCTYL TRIMELLITATE is a plasticizer that was evaluated for endocrine disrupting activities through estrogen receptor alpha binding assay.
Production MethodsTOTM is manufactured by acid-catalyzed esterification of trimellitic anhydride and 2-ethylhexanol.
DefinitionChEBI: Tri-2-ethylhexyl trimellitate is a benzoate ester.
General DescriptionYellow oily liquid.
Air & Water ReactionsInsoluble in water.
Reactivity ProfileTRIOCTYL 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 HazardTrioctyl trimellitate is probably combustible.
Flammability and ExplosibilityNonflammable
Safety ProfileVery low toxicity by ingestion.When heated to decomposition it emits acrid smoke andirritating vapors.
