空気 化学特性,用途語,生産方法

使用

This synthetic air is a colourless, odourless gas mixture of N₂ and O₂ with the same weight as air. Applications include gas chromatography with use as a zero gas or oxidizing gas for flame ionization detectors(FID). Gas is easy to handle in a small, light pressure can, while the disposable container allows for aluminium recycling when finished.

一般的な説明

Ordinary air liquefied. Shipped unconfined at its boiling point (approx -300°F). Noncombustible but promotes the burning of other materials. Can cause serious injury by freezing exposed skin.

反応プロフィール

Almost any reducing agent and all hydrocarbons can form explosive mixtures with liquid air [Chem. Eng. News 27:2612. 1949]. Explosions have occurred when liquid air contacts organic matter. A cracked tube of activated charcoal immersed in liquid air exploded violently [J. Sci. Inst. 5:24. 1928]. Allyldimethylarsine ignites in air and on filter paper [NFPA 491M. 1991]. Contact of very cold liquefied gas with water may result in vigorous or violent boiling of the product and extremely rapid vaporization due to the large temperature differences involved. If the water is hot, there is the possibility that a liquid "superheat" explosion may occur. Pressures may build to dangerous levels if liquid gas contacts water in a closed container [Handling Chemicals Safely 1980].

健康ハザード

Vapors may cause dizziness or asphyxiation without warning. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating and/or toxic gases.

火災危険

Substance does not burn but will support combustion. Some may react explosively with fuels. May ignite combustibles (wood, paper, oil, clothing, etc.). Vapors from liquefied gas are initially heavier than air and spread along ground. Runoff may create fire or explosion hazard. Containers may explode when heated. Ruptured cylinders may rocket.
