Thanks rrkss. That's good to know. It seems that EtOH wouldn't be good for Grignards though?

Nope but theres two factors to consider: a) Its only 1.5% and b) A good chemist will always distill his freshly dried solvent just before the reaction ;)

By the way, the KI method is only for extreme levels of peroxides, as far as I have experienced.

FeSO4 test is more sensitive if even if small levels of peroxides are present. Would use this any time over KI method.




Any sufficiently advanced technology is indistinguishable from magic.

re disposal

Model airplaners might buy it through an online auction. You'd want locals, to avoid having to ship it.

Or mix it into your petrol tank, or into 2-stroke fuel.

TERRIBLE advice! Ether will make a gasoline engine predetonate (knock).
