Aluminum galinstan Al/GaInSn is an amalgam of aluminum and galinstan used for reductive amination. It's a useful and non-toxic alternative to aluminum mercury Al/Hg.
I heated galinstan and aluminum and stirred to make aluminum galinstan.

I reduced phenyl-2-butanone (or P-2-Bu), and ammonia in ethanol solution using aluminum galinstan and then filtered to make phenylisobutylamine, and dried it with anhydrous magnesium sulfate. Then reacted the phenylisobutylamine ethanol solution with hydrogen chloride gas to make phenylisobutylamine HCl. The liquid galinstan was recoverable and reusable.
