Washing to remove HBr.
« on: July 01, 2018, 04:38:25 AM »
In a reaction where the solvent is Ethyl Acetate, Hydrogen Bromide is produced. Most is evolved from the solution but some remains, what is the best way to remove it? Is a water wash enough or would there be a better option such as aqueous Sodium Carbonate/Hydroxide?

do not wash with sodium hydroxide as it hydrolyses the ethyl acetate. sodium bicarbonate will do it. just be careful with it in the seperatory funnel as a lot of CO2 will be produced.
