Abstract

Abstract:

The problem of whether α-AlH₃ crystallized by aluminum hydride etherates(AlH₃·nEt₂O) stored for varying time is systematically studied. First, AlH₃·nEt₂O was prepared by a conventional method and stored under a nitrogen atmosphere for 1 to 20 days, and then α-AlH₃ was prepared by a solid phase and vacuum crystallizing technique based on the AlH₃·nEt₂O. XRD, TGA and SEM analysis show that the ether composition gradually decreases during storage and α-AlH₃ with higher purity can be prepared within 10 days of storage. However, after 10 days, γ-AlH₃ with smaller particle size appeared. Finally, we confirm that the amount of ether in AlH₃·nEt₂O is directly related to the quality of prepared α-AlH₃. Another highlight of this paper is the abandonment of the toxic reagent toluene used in conventional processes. This also provides a possibility for the kilogram preparation of α-AlH₃.
