Extraction of carboxylic acids with amine extractants. 1. Equilibria and law of mass action modeling
Studies have been made of the extraction of acetic, lactic, succinic, malonic, fumaric, and maleic acids by Alamine 336, an aliphatic, tertiary amine extractant, dissolved in various diluents. TheExpand

Extraction of carboxylic acids with amine extractants. 3. Effect of temperature, water coextraction, and process considerations
Coextraction of water during extraction of succinic acid by Alamine 336 in different dulents has been measured. The amounts of coextracted water lie in the same order as the solubilities of water inExpand
