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.
