this has been discussed (again) about a month ago... Evaporate sea water
and salt remains...
But, could EtBr sublimate? Or could it be distilled (especially when
heating in microwave that "shakes" every single water molecule and
generates way higher temps locally)? Could HBr be generated and make it
volatile (the rest of this aromatic polycycle is stable and likely to
From physico-chemical info (posted here) I found no indication that it
would behave in such manners...
