티이피피 화학적 특성, 용도, 생산

화학적 성질
Water-white to amber liquid depending on purity; hygroscopic. Miscible with water and all organic solvents except aliphatic hydrocarbons; hydrolyzed in water with formation of mono-, di-, and triethyl orthophosphates; water solutions attack metals; commercial material contains 40% TEPP.
물리적 성질
Colorless to amber liquid with an agreeable, fruity odor
용도
Insecticide for aphids and mites, rodenticide.
일반 설명
Water-white to amber liquid, depending on purity.
공기와 물의 반응
Hygroscopic. Hydrolyzed in water with formation of mono. di, and triethyl orthophosphates, water solutions attack metal surfaces. Reacts slowly with water to form phosphoric acid
반응 프로필
Organophosphates, such as TETRAETHYL PYROPHOSPHATE, 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.
위험도
Toxic by skin contact, inhalation, or ingestion; rapidly absorbed through skin; repeated exposure may, without symptoms, be increasingly hazardous; cholinesterase inhibitor, use may be restricted.
건강위험
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
화재위험
Combustible material: may burn but does not ignite readily. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
Safety Profile
Human poison by ingestion and intramuscular routes. Experimental poison by ingestion, skin contact, intraperitoneal, intramuscular, subcutaneous, parenteral, and intravenous routes. Human systemic effects by ingestion, intramuscular, and parenteral routes: paresthesia, wakefulness, excitement, muscle contraction or spasticity, nausea or vomiting and other gastrointestinal changes. The action is sidar to that of parathion: causing an irreversible inhbition of the cholinesterase molecules and the consequent accumulation of large amounts of acetylcholine. Small doses at frequent intervals are largely additive. When heated to decomposition it emits toxic fumes of POx. See also PARATHION.
잠재적 노출
A potential danger to those engaged in the manufacture, formulation and application of this aphicide and acaricide; used as an insecticide to control aphids, thrips, and mites; as an anticholinesterase.
환경귀착
Chemical/Physical. Tetraethyl pyrophosphate is quickly hydrolyzed by water. The hydrolysis half-lives at 25 and 38°C are 6.8 and 3.3 hours, respectively (Sittig, 1985).
Decomposes at 170–213°C releasing large amounts of ethylene (Hartley and Kidd, 1987; Keith and Walters, 1992).

비 호환성
Tetraethyl pyrophosphate may be susceptible to formation of highly toxic and flammable phosphine gas in the presence of hydrides and other strong reducing agents. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides. Hygroscopic. Hydrolyzed in water with formation of mono. di-, and triethyl-orthophosphates. Reacts slowly with cold water forming phosphoric acid. Attacks metals in the presence of water.
폐기물 처리
Return refillable compressed gas cylinders to supplier. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal. TEPP is 50% hydrolyzed in water in 6.8 hours @ 25℃, and 3.3 hours @ 38℃; 99% hydrolysis requires 45.2 hours @ 25 ℃, or 21.9 hours @ 38℃. Hydrolysis of TEPP yields nontoxic products. Incineration is, however, an option for TEPP disposal. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
