Description
Technical field
The present invention relates to hazardous chemical emergency disposal agent field, in particular to a kind of aniline leaks emergency disposal agent.
Background technique
The aniline amine substance important as one kind, it is very extensive in organic synthesis and chemical products field purposes, it is dye
One of most important raw material in the industrial productions such as material, pesticide, rubber.Aniline is more toxic, and can cause to be poisoned on a small quantity, to people
Body has carcinogenesis；Aniline, which also has, fires danger, and the accidents such as fire, explosion can be caused by meeting open fire.With the hair of social economy
Exhibition often leaks during the mass production of aniline is with being widely used, not only causes pollution to environment, also give
Human body, animals and plants or other biological bring great harm.
Emergency disposal is the primary measure after dangerous chemical leakage accident occurs, and is to prevent harmful influence sprawling diffusion, to the greatest extent
Possibly reduce or remove the effective ways of its harm.Correct emergency disposal agent is selected, is the success of leakage accident emergency disposal
Important prerequisite.Aniline is a kind of volatile liquid, and in the emergency disposal after its leakage, primary measure is to leakage
The disposition of aniline liquid and its steam: the concentration of benzene in air amine steam is on the one hand reduced；On the other hand leakage aniline liquid is prevented
The trickling of body can quickly be solidified and be concentrated in region small as far as possible, be diffused into other regions to prevent its flowing, expanded dirty
Contaminate range；The secondary volatilization for inhibiting aniline liquid as far as possible simultaneously, prevents the concentration of aniline in air from rising again, is emergency management and rescue
Personnel enter leak scene and provide necessary condition.
From the prior art, it there is no the dedicated emergency treatment agent for aniline leakage.To aniline steam, usually use
Water mist or foam are diluted；The solubility of aniline in water is low, and the aniline after water mist or foam disposition is easy to volatilize again,
The concentration of aniline in air is caused to rise again.To liquid aniline, mainly adsorbed using sand or other incombustible materials, but
These adsorbents are easy by the external conditions such as heat up to be influenced that aniline is caused to be desorbed, benzene to the limited sorption capacity of aniline
Amine steam evaporates again causes secondary hazards.
