Aluminium carbide

Interaction with aluminium carbide is incandescent, and with caesium acetylide at 350°C is explosive. Other related compounds may be expected to be oxidised violently if unmoderated. 

Why can calcium carbide be called an acetylide, while beryllium and aluminium carbides cannot be given this name ... 

Reaction LVI. Action of Water on certain Metallic Carbides. (J. C. S., 87, 1232.)—This reaction has an important and well-known application in the production of acetylene on an industrial scale. Methane can be obtained in a similar way from aluminium carbide. 

Methane is prepared from aluminium carbide and dilute hydrochloric acid in a similar apparatus. It is purified as described on p. 182.

By the action of water on aluminium carbide, methane is obtained3 admixed, however, with a little hydrogen.4... 

Methane-14 was prepared (Ciranni and Guarino, 1966) from aluminium carbide and pure T2O. The crude CT4, specific activity of 116,500 Curies per mole, was immediately diluted with a large excess of CH4 and subjected to a rigorous purification, including a preparative gas-chromatographic separation over a special capillary column that allows (Bruner and Cartoni, 1965) the complete resolution of the four tritiated methanes, from CH3T to CT4. The final sample, whose isotopic purity is illustrated in Fig. 5, was further diluted with CH4 to a specific activity of 0-2 Curies per mole to carry out the decay experiments. Nefedov et al. (1968) used CT4 prepared by essentially the same procedure in their study of the reactions of methyl ions in hydroxylic compounds. 

Mercuric chloride is dissolved in a very dilute aqueous solution of hydrochloric acid and an equal weight of aluminium carbide added, mercury dimeth5d soon separates. ... 

Nersesyants et al. [91] were successful in using this method for the separate determination of aluminium and aluminium carbide. A solid sample was treated with an acid, and the gas evolved was collected in a gas volume-measuring device. The gas composition was determined on a column containing molecular sieves by conventional gas chromatography. The hydrogen content is proportional to that of the metal in the sample, and the content of the organic gaseous component corresponds to that of the carbide [91]. 

The compound is also formed when aluminium carbide is treated with water ... 

Strongly electropositive metal carbides react to form flammable hydrocarbon gases, e.g., aluminium carbide gives methane.
