Its high ability to poison doesn't come from the hydrogen chloride released by a process.
Even in the absence of water, hydrogen chloride can still act as an acid.
A small molecule, usually water, or hydrogen chloride, is eliminated.
Most hydrogen chloride is used in the production of hydrochloric acid.
It can also be made by reacting hydrogen chloride with oxygen and a catalyst.
The process was based on the oxidation of hydrogen chloride:
The hydrogen chloride gas bubbles off and is discarded.
Most hydrogen chloride produced on an industrial scale is used for hydrochloric acid production.
In this reaction hydrogen chloride is generated, which forms a salt with the amine.
Breathing in gas with more than fifty parts per million of hydrogen chloride can cause death in humans.
