Liquid-liquid distribution of B group vitamins in polyethylene glycol-based systems

General regularities of the liquid-liquid distribution of B 1 , B 2 , B 6 , and B 12 vitamins in aqueous polyethylene glycol (PEG-2000, PEG-5000) solution-aqueous salt solution systems are studied. The influence of the salting-out agent, the concentration of the polymer, and its molecular weight on...

Zusammenfassung:	General regularities of the liquid-liquid distribution of B 1 , B 2 , B 6 , and B 12 vitamins in aqueous polyethylene glycol (PEG-2000, PEG-5000) solution-aqueous salt solution systems are studied. The influence of the salting-out agent, the concentration of the polymer, and its molecular weight on the distribution coefficients and recovery factors of the vitamins are considered. Equations relating the distribution coefficients (log D ) to the polymer concentration are derived.
