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.

Production Methods

TOTM is manufactured by acid-catalyzed esterification of trimellitic anhydride and 2-ethylhexanol.

Definition

ChEBI: Tri-2-ethylhexyl trimellitate is a benzoate ester.

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.
