Trioctyl trimellitate Chemical Properties,Uses,Production
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.
Definition
ChEBI: Tri-2-ethylhexyl trimellitate is a benzoate ester.
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
Non flammable
Safety Profile
Very low toxicity by ingestion.When heated to decomposition it emits acrid smoke andirritating vapors.
