Abstract
벤조산과 그 유도체들에 대한 음이온 교환분리를 여러 농도의 염화니켈-메탄올 용매 내에서 연구하였다. Amberlite CG-400, Cl- form에 대한 유기산들의 부피분배계수를 측정하고 이 분배계수로부터 제시된 적절한 농도의 NiCl2-MeOH 용액을 용리액으로 사용하여 몇 개의 혼합유기산을 정량적으로 분리하였다. 모든 유기산들의 농도는 자외선 분광광도계를 사용하여 정량하였다.

The anion exchange separation of a number of benzoic acid and its derivatives has been studied in various concentrations of NiCl2-methanol solvent medium. The volume distribution coefficients with Amberlite CG-400, Cl- form have been measured in these medium. Several synthetic mixtures of organic acids were separated quantitatively by elution with a suitable concentration of NiCl2-MeOH solution suggested by the distribution data. The concentration of organic acids were determined by UV spectrophotometry.
