RCRA 요건	P062As stipulated in 40 CFR 261.33, when hexaethyltetraphosphate, as a commercial chemical product or manufacturing chemical intermediate or an off-specification commercial chemical product or a manufacturing chemical intermediate, becomes a waste, it must be managed according to federal and/or state hazardous waste regulations. Also defined as a hazardous waste is any container or inner liner used to hold this waste or any residue, contaminated soil, water, or other debris resulting from the cleanup of a spill, into water or on dry land, of this waste. Generators of small quantities of this waste may qualify for partial exclusion from hazardous waste regulations (40 CFR 261.5(e)).

용도

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.

일반 설명

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.
