Dielectric aluminium compounds

Due to their good donor properties formamide and acetamide dissolve many ionic compounds7 94,96 g ch as alkali halides, various salts of copper, zinc, cadmium, aluminium, tin, lead, nickel, mercury and other acceptor compounds, such as FeCls or SbCls. The high dielectric constants allow considerable dissociation of the compounds ionized in the solutions. 

Pb(CH3)4 can be applied to extract aluminium and alkylaluminium alkoxide impurities from organoaluminium complexes used in the electrolytic preparation of tetraorganolead compounds [177]. Pb(CH3)4 was claimed to prevent corrosion of graphite by CO2 used as fluid coolant in nuclear reactors [178], and to stabilize halogenated aryl compounds, employed as dielectric, insulating, or cooling agents [179].
