Reaction Equilibrium of Penicillin G with Amberlite LA‐2 in a Nonpolar Organic Solvent

Biotechnology Progress, 2002
Abstract Studies have been made of the reactive extraction of penicillin G by Amberlite LA‐2, a secondary amine, dissolved in kerosene. On the basis of the previous works about extraction equilibria of monocarboxylic acids by some secondary amines in low polar organic solvents, four equilibrium models were suggested to describe the ...

Comparative Equilibrium Studies for Citric Acid by Amberlite LA-2 or Tridodecylamine (TDA)

Journal of Chemical & Engineering Data, 2009
Carboxylic acids like citric acid are produced by fermentation. They have been used in many industrial fields as intermediate and starting materials, and their importance is still growing. It is important to separate them from the fermentation broth. In this sense, comparison of different types of solvents and amines for extraction of carboxylic acids ...

Comparative Study on Reactive Extraction of Nicotinic Acid with Amberlite LA‐2 and D2EHPA

Separation Science and Technology, 2007
Abstract The comparative study of reactive extraction of nicotinic acid with Amberlite LA‐2 and D2EHPA in three solvents with different polarity indicated that the extractant type and solvent polarity control the extraction mechanism. Thus, the reactive extraction with Amberlite LA‐2 in low‐polar solvents occurs by means of the interfacial formation of
