of FeBr3 that then makes a complex [ph-Br]+[FeBr4]- -> ph-Br + HBr + FeBr3
@Nicodem: thanks, very interesting and answered my question. The foirmation of dibrom products is a sideraction that requires workup. I've seen
steam distillation recommended and I don't like the idea vey much. It would mean distilling twice and a lot of water removal. Why not simply do a
fractional distillation? Do you see any reasons for steam and not frax first time through instead?
