| Hazard Information | Back Directory | 【General Description】
A colorless gas with a faint garlic-like odor. Easily ignited and burns with a sooty flame. Gas is lighter than air. Flame may flash back to the source of a leak very easily. Under prolonged exposure to fire or heat the containers may rupture violently and rocket. | 【Reactivity Profile】
ACETYLENE(74-86-2) reacts with alkali metals, forming Hydrogen gas. ACETYLENE(74-86-2) can react explosively with bromine [Von Schwartz 1918. p.142 ]. ACETYLENE(74-86-2) forms a sensitive acetylide when passed into an aqueous solution of mercuric nitrate, [Mellor 4:933. 1946-47]. An ACETYLENE(74-86-2) torch used to drill through a plow frame, which was filled with hydrogen gas, produced an explosion [NIOSH, June 1998]. ACETYLENE(74-86-2) reacts with silver, copper and lead to form sensitive, explosive salts. Since ACETYLENE(74-86-2) is endothermic and effectively a reducing agent, it's reaction with oxidants can be very violent (examples: calcium hypochlorite, nitric acid, nitrogen oxide, ozone, trifluoromethyl hypofluorite, etc.). 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]. ACETYLENE(74-86-2) and ammonia can form explosive silver salts in contact with Ag. (Renner, Hermann, Gunther Schlamp. "Silver, Silver Compounds, and Silver Alloys." Ullmann's Encyclopedia of Industrial Chemistry. Wiley-VCH Verlag GmbH & Co. KGaA. 2001.). | 【Air & Water Reactions】
Highly flammable. Slightly soluble in water. Reacts with water to form toxic ammonia fumes. | 【Health Hazard】
Headache, dizziness and loss of consciousness may occur. Death from ``smothering'' may occur if oxygen content of the air is severely reduced by dilution with acetylene. | 【Fire Hazard】
Behavior in Fire: May explode in fire |
