Regeneration of carboxylic acid-laden basic sorbents by leaching with a volatile base in an organic solvent
Patent

OSTI ID:20013949
Carboxylic acids are sorbed from aqueous feedstocks onto a solid adsorbent. The acids are freed from the sorbent phase by treating it with an organic solution of alkylamine thus forming an alkylamine/carboxylic acid complex which is decomposed with improved efficiency to the desired carboxylic acid and the alkylamine. Carbon dioxide addition can be used to improve the adsorption of the carboxylic acids by the solid phase sorbent.
