ABSTRACT:
Concentrated acetic acid of 95 to 100 weight percent concentration containing both ionic and coordinate bromine can be successfully purified to a bromine content of less than 3 ppm by the sequential steps of catalytic hydrogenation, contacting the resulting acetic acid with alkali metal hydroxide, carbonate or bicarbonate, and then distilling acetic acid from the alkali metal.
