四りん酸ヘキサエチル 化学特性,用途語,生産方法
化学的特性
Hexaethyl tetraphosphate is a yellow liquid which is miscible with water and many organic solvents except kerosene; hydrolyzes in low concentration; hygroscopic. decomposes at high temperatures. It is difficult to burn. It is toxic by skin absorption and inhalation. It is a mixture of ethyl phosphates and ethyl pyrophosphate. It decomposes at high temperatures. May be found in the form of a dry mixture where the liquid is absorbed onto a dry carrier.
使用
Hexaethyl tetraphosphate is used as an insecticide, in particular, the insecticide Bladan. The Germans commonly used this chemical as an insecticide during World War II, when nicotine-based insecticides were not available.
定義
A mixture of ethyl phosphates and ethyl pyrophosphates (TEPP).
一般的な説明
Tetraethyl pyrophosphate solid is a solid material on which the phosphate itself is absorbed. The phosphate itself is combustible though Hexaethyl tetraphosphate may take effort to ignite. Hexaethyl tetraphosphate is soluble in water and gradually decomposed by it. Hexaethyl tetraphosphate is toxic by inhalation(dust, etc) and by skin absorption.
空気と水の反応
Hexaethyl tetraphosphate is soluble in water and gradually decomposed by it.
反応プロフィール
Organophosphates 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.
危険性
Toxic by ingestion, inhalation, and skin
absorption; cholinesterase inhibitor.
健康ハザード
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.
火災危険
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.
