Abstract
Metallic aluminium is reacted with an aluminium alkyl and hydrogen at elevated temperature and pressure to give an alkyl aluminium hydride. The reaction may be carried out at a temperature within the range 60 DEG to 200 DEG C. (preferably about 100 DEG to about 140 DEG C.), and under a pressure of at least 150 atmospheres. The reaction temperature should not exceed the decomposition temperature of the alkyl aluminium hydride. The aluminium should preferably be free from oxide coating; this may be removed by milling the rod submerged in an inert solvent in the absence of oxygen. Preferably the reaction is conducted in the presence of an alkyl halide (ethyl iodide or n-propyl bromide) or an alkyl aluminium halide as activator, and of an inert solvent such as a paraffinic or alicyclic hydrocarbon. Water and oxygen should not be present, the preparation being carried out in an inert atmosphere of, e.g., nitrogen. The alkyl aluminium hydrides may be used as catalysts in the polymerization of olefins, or may be reacted with a -olefines at elevated temperature and pressure to produce aluminium trialkyls, thus dipropyl aluminium hydride reacts with propylene to give aluminium tripropyl. In an example finely-divided aluminium is suspended in a solution of aluminium triethyl in methylcyclohexane and heated in an autoclave in the presence of hydrogen at 100 DEG C. and 250 atmospheres pressure. The aluminium sesquibromide with sodium. The product was filtered in a nitrogen atmosphere to give a solution containing ethyl aluminium hydrides. This solution was then reacted with ethylene at 100 DEG C. and 100 atmospheres pressure to give a solution containing aluminium triethyl.
