Tris(1-Chloro-2-Propyl) Phosphate Usage And Synthesis

Chemical Properties

Tris(2-chloro-1-methylethyl) phosphate is clear colorless oily liquid with high water solubility and low lipophilicity (as indicated by logKOW). This substance ismanufactured as a reactionmixture, which contains four isomers. It is the primary isomer in the mixture at 50–85% weight/weight (w/w), followed by bis(1- chloro-2-propyl)-2-chloropropyl phosphate [15–40% (w/w); CASRN: 76025-08-6], bis(2-chloropropyl)-1-chloro-2-propyl phosphate [<15% (w/w); CASRN: 76649-15-5], and tris(2- chloropropyl) phosphate [<1% (w/w); CASRN: 6145-73-9] (EURAR, 2008).

Uses

Tris(1-chloro-2-propyl) Phosphate is a flame retardant of low hydrolytic stability, used in polyurethane (PU) rigid and flexible foam, PVC, EVA, phenolics and epoxy resin.

Definition

ChEBI: Tris(1-chloropropan-2-yl) phosphate is a trialkyl phosphate.

General Description

Clear colorless viscous liquid. Tris(2-chloroisopropyl) Phosphate(TCPP), mixture of isomers is suitable for use in environmental and food residue analysis. It is a mixture of isomers, composition may vary, typical composition: main isomer tris(1-chloro-2-propyl) phosphate 66%, minor components: bis(1-chloro-2-propyl) (2-chloropropyl) phosphate and (1-chloro-2-propyl) bis(2-chloropropyl) phosphate.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Phosphoric acid tris(2-chloro-1-methylethyl) ester may hydrolyze under acidic or alkaline conditions.

Health Hazard

ACUTE/CHRONIC HAZARDS: When heated to decomposition Phosphoric acid tris(2-chloro-1-methylethyl) ester emits very toxic fumes.

Fire Hazard

Phosphoric acid tris(2-chloro-1-methylethyl) ester is probably combustible.

Toxicology

Tris(1-Chloro-2-Propyl) Phosphate (TCPP) is considered a suspected carcinogenic, suspected reprotoxic, and suspected PBT (persistent, bioaccumulative and toxic) and is a potential endocrine disruptor (ECHA, 2019).  Thus, the presence of TCPP in the receiving water can affect aquatic organisms and potentially affect human health.
