Aluminium borohydride, also known as aluminium tetrahydroborate, (in American English, aluminum borohydride and aluminum tetrahydroborate, respectively) is the chemical compound with the formula Al(BH4)3. It is a volatile pyrophoric liquid which is used as rocket fuel or jet fuel, or as a reducing agent in laboratories.
Preparation
Aluminium borohydride is formed by the reaction between sodium borohydride with aluminium chloride[2]:
- 3NaBH4 + AlCl3 → Al(BH4)3 + 3NaCl
or as the non-pyrophoric THF adduct, by the analogous reaction of calcium borohydride and aluminium chloride in tetrahydrofuran:[3]
- 3 Ca(BH4)2 + 2 AlCl3 → 3 CaCl2 + 2 Al(BH4)3
Reactions
Like all borohydrides, this compound is a reducing agent and hydride donor. It reacts with water to give elemental hydrogen gas[2], and reduces carboxylic esters, aldehydes, and ketones to alcohols.[3]
