Process for recovery of a carboxylic acid from a feed stream containing the corresponding ester |
| abstract |
A carboxylic acid e.g. acetic acid, is recovered from an aqueous feed stream containing the corresponding ester, an alcohol and a small amount of water by catalytically dehydrating the alcohol to the corresponding ether and water, and reacting the water with the ester to generate a liquid carboxylic acid rich product stream. The acid is recovered by distillation. In a second embodiment, additional alcohol and/or water are co-fed with the feed or fed directly to a catalytic distillation column, resulting in a liquid bottom product stream of substantially pure acetic acid and a top distillate stream of substantially pure ether. |
