Aluminium iodide

Aluminium powder bums when heated in carbon dioxide, and presence of aluminium chloride or aluminium iodide vapour in carbon monoxide or carbon dioxide accelerates the reaction to incandescence. 

In the preparation of aluminium iodide etherate from the elements in ether, the aluminium must be as turnings, rather than fine powder, to keep the reaction under control.

Ammino-aluminium Iodides,—Aluminium iodide is soluble in liquid ammonia, forming a colourless solution from which, on cooling to —83° C., a crystalline solid of composition A1I3.20NH3 separates. On rise of temperature it loses ammonia, and at S° to 13° C. the composition is that of hexammino-aluminium iodide, [A1(NII3)6]I3. Weber2 found that aluminium iodide absorbs ammonia gas slowly at first, and on warming a white voluminous powder was formed which contains at least four molecules of ammonia for every molecule of the iodide. It decomposes with loss of ammonia on treatment with water. 

Boron, which occurs in the second period of the periodic system as a tervalent ion, is naturally very small (see Table F), and, in the compounds which it forms with the halogens, the boron ion will be completely shielded by the three halogen ions, so that the boron halides are thus compounds with low boiling points. Of the halogen ions, iodine, which contains the most electrons, is the largest. In aluminium iodide the three iodine ions will shield the aluminium ion, as also do the somewhat smaller bromine or chlorine ions in... 

Within the context of mixed Lewis-acid catalysts, Marek and Lopour also showed that if aluminium iodide was used, its best partner in terms of initiation efficiency was titanium tetrachloride. 

By bubbling gaseous chlorine through chloroacetophenone in presence of aluminium iodide or chloride, aa-dichloroaceto-phenone is formed ... 

Aluminium triphenyl is the sole aluminium aromatic organic compound. Like the corresponding alkyls, it forms an etherate, but its decom K>sition by air is not so rapid. Mercury diphenyl and aluminium in a nitrogen atmosphere at 140 C. produce the compound, with much evoiution of heat, in a few seconds. Iodine decomposes it, with formation of aluminium iodide and iodobenzene. 

Condensation products formed by acetone and chloroform do not appear to ha "e been very thoroughly investigated, but iodine decomposes aluminium triphenyl, yielding aluminium iodide and iodobenzene.

In the question, you start with lOg of aluminium, so what masses of iodine and aluminium iodide are involved if the above ratio is to apply ... 

The water will vaporise. Purple iodine vapour will be produced. Sparks will be seen and a flame. An exothermic reaction is occurring between the aluminium and iodine. Energy is being released. When the reaction has finished, a white powder, aluminium iodide, will be present in the dish. 

Quaternary ammonium iodides have been found to improve the yield of aluminium iodide promoted aromatic ether cleavages to...
