Just something I've been wondering, since using a solvent that doesn't dissolve oxygen (anything but water?) would prevent aluminum oxide from forming
and keep the newly exposed surfaces pure aluminum.
Would this work, and has anyone tried it?Fulmen - 30-9-2023 at 12:32
Yeah, but only to a degree and for a short while. It's hard to completely prevent oxidation outside of a noble gas atmosphere. But I have successfully
tinned aluminum foil using some oil (silicon perhaps, I forget), although it was always a bit hit-and-miss.

By your estimation, would this method be useful for making aluminum isopropoxide under isopropanol?cirrostratus - 30-9-2023 at 21:54
Hey,
I've done a bunch of experiments with Aluminum Isopropoxide.
I've always been able to use scissored-up aluminum foil for making it, just with a catalytic amount of Iodine in the reaction flask. Even just a
couple of prills worth in a 500 ml set up. It takes a while for the reaction to get going though (like a couple of hours) so I usually just let it
reflux for a while.
Catalytic Iodine is also great for similar purposes in Grignards.
