Synthesis of sodium aluminum hydride Abstract

Sodium aluminium hydride is a strong , very similar in reactivity to (LAH) and, to some extent, (DIBAL) in organic reactions. It is much more powerful reducing agent than due to the weaker and more Al-H bond compared to the B-H bond. Like LAH, it reduces to .

There was used, 8.8 grams of sodium; (0.382 moles) and 35.0 grams ofaluminum; (1.296 moles).

Vitride(R), 70 Percent in Toluene, also known as Sodium bis(2-methoxyethoxy)aluminum hydride, is an organoaluminium compound. It is used as a reducing agent in organic synthesis. Ungraded products supplied by Spectrum are indicative of a grade suitable for general industrial use or research purposes and typically are not suitable for human consumption or therapeutic use. These materials may or may not have a Certificate of Analysis available.

Synthesis of lithium aluminum hydride

Since the reaction utilizes equimolar portions of sodium and aluminum, there was an excess equivalent to (2.87-1.0), or 1.87 moles of aluminum.

Sodium tetrahydroaluminate can release up to 7.4 wt % of hydrogen when heated at 200 °C (392 °F). can be slow, several minutes being required to fill a tank. Both release and uptake are catalysed by .

Sodium tetrahydroaluminate adopts the structure of (is isostructural with) . As such, the tetrahedral AlH4- centers are linked with eight-coordinat Na+ cations. The compound is prepared from the elements under high pressures of H2 at 200 °C using catalyst:

Sodium aluminium hydride is highly flammable. It does not react in dry air at room temperature but is very sensitive to moisture. It ignites or explodes on contact with water.

Sodium aluminium hydride or sodium alanate is an with the NaAlH4. It is a white solid that dissolves in , but not in or hydrocarbons. It has been evaluated as an agent for the reversible storage of hydrogen and it is used as a for the of . Similar to , it is a consisting of separated and tetrahedral AlH4 .
