Alkali metals chemical incompatibilities

Chemical Incompatibility Hazards While N2 and C02 may act as inerts with respect to many combustion reactions, they are far from being chemically inert. Only the noble gases (eg., Ar and He) can, for practical purposes, be regarded as true inerts. Frank (Frank, Inerting for Explosion Prevention, Proceedings of the 38th Annual Loss Prevention Symposium, AIChE, 2004) lists a number of incompatibilities for N2, C02, and CO (which can be present in gas streams from combustion-based inert gas generators). Notable incompatibilities for N2 are lithium metal and titanium metal (which is reported to burn in N2). C02 is incompatible with many metals (eg., aluminum and the alkali metals), bases, and amines, and it forms carbonic acid in water,... [Pg.37]

Earthquakes provide the ultimate test of the storage of incompatible chemicals and are sometimes followed by fires in chemical stores. Very few causes of ignition are found alkali metals halogen oxysalts in conjunction with strong acids and sulphuric or nitric acid and cellulose (wood flooring). These usually then ignite vapours of flammable solvents. [Pg.137]

SAFETY PROFILE A poison. Flammable by chemical reaction an oxidizer. Explosive reaction with hydrogen peroxide, chlorine + ethylene. Reacts violently with molten potassium, molten sodium, S, (H2S + BaO + air). Forms explosive mixtures with nonmetals [e.g., phosphorus (impact-sensitive), sulfur (friction-sensitive)]. Incompatible with alkali metals, reducing materials. Dangerous when heated to decomposition it emits highly toxic fumes of Hg. See also MERCURY COMPOUNDS, INORGANIC. [Pg.881]
