The resulting carboxylic acid halide or carboxylate salt can be used as an acylating reagent or alkylating reagent, and metal halide or onium halide liberated during this can be reacted anew with carboxylic anhydride and regenerated, thereby making it possible to effect a hydrolysis-free alkylation...

Replacing the cation of a carboxylate by H+ to get carboxylic acid (if required). 4. Concentration/purification. Removal of the bulk solvent or capture of the carboxylic acid, achieving concentration. Removal of remaining impurities. 5. Upgrading. Transformation to chemical derivatives (if required...
Thus, almost any carboxylic acid can be made to dissolve in water by converting it to such a salt, which is easily done by adding a strong base—most commonly sodium hydroxide (NaOH) or potassium hydroxide, (KOH). The calcium and sodium salts of propanoic (propionic) acid are used as ...

In many cases carboxylate salts are formed whereas carboxylic acids are desired. When converting carboxylate into carboxylic acid, H+ has to replace the counterion of the carboxylate (e.g. Na+). Depending on the required procedure, the removal will lead to a (sodium) salt or base as co-pro...
