Tris(2-butoxyethyl) phosphate Chemical Properties,Uses,Production

Chemical Properties

Slightly yellow, oily liquid. Insoluble or limited solubility in glycerol, glycols, and certain amines; soluble in most organic liquids. Combustible.

Uses

Primary plasticizer for most resins and elastomers, floor finishes and waxes, flame-retarding agent.

Uses

Tris(2-butoxyethyl) phosphate may be used as an analytical reference standard for the quantification of the analyte in herring gull eggs, house dust, and urine samples using liquid chromatography technique.

Definition

ChEBI: A trialkyl phosphate in which the alkyl group specified is 2-butoxyethyl.

General Description

Tris(2-butoxyethyl) phosphate is an organic flame retardant. It shows PXR agonistic activity. Tris(2-butoxyethyl) phosphate was detected and quantified during the analysis of herring gull eggs by liquid chromatography-electrospray ionization(+)-tandem mass spectrometry.

Air & Water Reactions

Water soluble.

Reactivity Profile

Organophosphates, such as Tris(2-butoxyethyl) phosphate, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides. Tris(2-butoxyethyl) phosphate may react with oxidizers. .

Fire Hazard

Tris(2-butoxyethyl) phosphate is combustible.

Flammability and Explosibility

Non flammable

Safety Profile

A poison by intravenous route. Moderately toxic by ingestion. A skin and eye irritant. Combustible when exposed to heat or flame. Dangerous; see also PHOSPHATES; can react with oxidizing materials. To fight fire, use water, foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of POx.

Toxics Screening Level

The initial threshold screening level (ITSL) for tris(2-butoxyethyl) phosphate is 8 μg/m 3 (annual averaging time).
