<p>PURPOSE:To effectively remove the corrosive gas remaining in the container valve of a gas sealing container sealing corrosive gas such as a gas cylinder container by using a corrosive gas absorbent composed of an org. substance having an unsaturated bond as an effective component. CONSTITUTION:Corrosive gas, for example, hydrogen chloride or chlorine gas is reacted with a corrosive gas absorbent component to be absorbed into a corrosive gas absorbent. That is, hydrogen chloride gas or chlorine gas produces an addition reaction, substitution reaction or rearrangement reaction with the corrosive gas absorbent component to form a halogenated org. compd. and, therefore, this gas is absorbed into the corrosive gas absorbent in a form taken in the corrosive gas absorbent component. As a result, even when corrosive gas remains in the container valve 2 of a gas cylinder container 1 having corrosive gas sealed therein, this gas is reacted with the corrosive gas absorbent component to be absorbed into the corrosive gas absorbent 4 to be removed. Therefore, the adverse effect on a human body or peripheral environment or the corrosion of the interior and piping part of the container valve 2 can be suppressed.</p> |
