WebAnswer (1 of 2): It’s called a workup. You do not reconvert aldehyde to carboxylic acid. workup is always opposite of what you do in the reaction. For example: If you run an acid-catalyzed reaction, what do you do afterward assuming the reaction is complete. Assume it is. You must add base to... WebHere, we present a protocol to remove aldehydes and reactive ketones from mixtures by a liquid-liquid extraction protocol directly with saturated sodium bisulfite in a miscible solvent. This combined protocol is rapid and facile to perform. The aldehyde or ketone can be re-isolated by the basification of the aqueous layer.
