Аннотация:Mechanochemically promoted reactions between sodium and aluminum binary hydrides in diethyl
ether in the presence of various promoters are studied. It is observed that a complexing reaction resulting in NaAlH4 is substantially promoted when LiAlH4 is added to the solution in a molar ratio of LiAlH4 : AlH3 = (12) : 1. NaAlH4 addition to the suspension has a smaller effect. In the presence of LiBH4, a cation-exchange reaction occurs to form LiAlH4 and NaBH4.
