NaAlH4 Chemical Structure

 

Dr. Zidan’s method2 uses a specifically formulated solution of NaAlH4 in tetrahydrofuran (Product No. 698865),3,4 developed by Aldrich Materials Science for use as the hydride source and electrolyte in the preparation of AlH3 by electrolysis as show in Equations 1 and 2.2
