tetramethylammonium hydroxide usage and synthesis |
chemical properties | colourless to yellow liquid |
general description | tetramethylammonium hydroxide is a solid in the hydrated form or a colorless liquid with a strong ammonia-like odor. tetramethylammonium hydroxide is soluble in water. tetramethylammonium hydroxide is corrosive to metals and tissue. |
air & water reactions | tetramethylammonium hydroxide is soluble in water. |
reactivity profile | tetramethylammonium hydroxide acts like a base. bases are chemically similar to sodium hydroxide (naoh) or sodium oxide (na2o). they neutralize acids exothermically to form salts plus water. when soluble in water they give solutions having a ph greater than 7.0. mixing these materials with water can generate troublesome amounts of heat as the base is dissolved or diluted. bases react with certain metals (such as aluminum and zinc) to form oxides or hydroxides of the metal and generate gaseous hydrogen. bases may initiate polymerization reactions in polymerizable organic compounds, especially epoxides). they may generate flammable and/or toxic gases with ammonium salts, nitrides, halogenated organics, various metals, peroxides, and hydroperoxides. materials of this group often serve as catalysts. |
health hazard | toxic; inhalation, ingestion or skin contact with material may cause severe injury or death. contact with molten substance may cause severe burns to skin and eyes. avoid any skin contact. effects of contact or inhalation may be delayed. fire may produce irritating, corrosive and/or toxic gases. runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. |
fire hazard | combustible material: may burn but does not ignite readily. when heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. contact with metals may evolve flammable hydrogen gas. containers may explode when heated. runoff may pollute waterways. substance may be transported in a molten form. |
