Characteristics-
PSA:
54.57000
XLogP3:0.8 (LogP)
Appearance:Triethyl phosphate appears as a colorless, corrosive liquid. Combustible. Slowly dissolves in water and sinks in water. Severely irritates skin, eyes and mucous membranes.
Density:1.0725 g/cm3 @ Temp: 19 °C
Melting Point:-56.4 °C
Boiling Point:215-216 °C
Flash Point:130ºC
Refractive Index:1.405-1.407
Water Solubility:H2O: soluble
Storage Conditions:Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
Vapor Pressure:1 mm Hg ( 40 °C)
Vapor Density:6.28 (vs air)
Toxicity:LD50 orally in Rabbit: 1165 mg/kg
Odor:Mild
OH:5.53e-11 cm3/molecule*sec
Henrys Law Constant:3.60e-08 atm-m3/mole|Henry's Law constant = 3.60X10-8 atm-cu m/mol at 20 °C
Collision Cross Section:132.63 Ų [M+H]+
Experimental Properties:Liquid molar volume = 0.1708 cu-m/kmol; Enthalpy Heat of Formation = -1.245X10+9 J/kmol|Dielectric constant = 13.20|Hydroxyl radical reaction rate constant = 5.53X10-11 cu cm/molec-sec at 25 °C
Air and Water Reactions:Slowly dissolves in water with slight decomposition (NTP, 1992).
Reactive Group:Esters, Sulfate Esters, Phosphate Esters, Thiophosphate Esters, and Borate Esters
Reactivity Profile:Organophosphates, such as TRIETHYL 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.
Autoignition Temperature:845 °F (USCG, 1999)|850 °F (454 °C)|452 °C
