Gases common materials

Dry chlorine has a great affinity for absorbing moisture, and wet chlorine is extremely corrosive, attacking most common materials except HasteUoy C, titanium, and tantalum. These metals are protected from attack by the acids formed by chlorine hydrolysis because of surface oxide films on the metal. Tantalum is the preferred constmction material for service with wet and dry chlorine. Wet chlorine gas is handled under pressure using fiberglass-reinforced plastics. Rubber-lined steel is suitable for wet chlorine gas handling up to 100°C. At low pressures and low temperatures PVC, chlorinated PVC, and reinforced polyester resins are also used. Polytetrafluoroethylene (PTFE), poly(vinyhdene fluoride) (PVDE), and... 

The gas is essentially inert to common materials of construction such as stainless steel under normal conditions of use. Platinum and gold are also not attacked by pure hydrogen chloride. 

Chemical Reactivity - Reactivity with Water Reacts violently, forming corrosive and toxic fumes of hydrogen bromide Reactivity with Common Materials Attacks and corrodes wood and most metals in the presence of moisture. Flammable hydrogen gas may collect in enclosed spaces Stability During Transport Stable if protected from moisture Neutralizing Agents for Acids and Caustics Hood with water, rinse with dilute sodium bicarbonate or soda ash solution Polymerization Not pertinent Inhibitor of Polymerization Not pertinent. 

Chemical Reactivity - Reactivity with Water No reaction Reactivity with Common Materials Corrosive to aluminum, zinc and tin. Contact with some metals can generate flammable hydrogen gas Stability During Transport Stable Neutralizing Agents for Acids and Caustics Dilute with water and rinse with dilute acetic acid Polymerization Not pertinent Inhibitor cf Polymerization Not pertinent. 

Chemical Reactivity - Reactivity with Water. Reacts slowly to form flammable hydrogen gas. The reaction is not hazardous unless water is hot or unless confined Reactivity with Common Materials Corrosive to natural rabber, some synthetic robbers, some greases and some lubricants Stability During Transport Stable below 302° F Neutralizing AgerUs for Acids and Caustics Not pertinent Polymerization Not pertinent Inhibitor of Polymerization Not pertinent.
