If you have a can of ether around do you have some Chloroform around as well?  |
it does not evaporate but oxidzes to peroxide. Very common in organic labs to evaporate ether to obtain the product. Kids have blown up flasks in rotarvaps from using old oxidized stock ether... So evaporation is very normal process that is safe. Bubbling O2 in ether would produce the peroxide. The can in question is way outdated. I would assume pre80's SOP.
Multiple different types. Mostly CDCl3 as normal chloroform is just a more polar solvent than water.
