โœฆ Synopsis

Comples mistures of dicarbosylic acids are separated by anion-eschange chromatography in sodium sulphate and determined automatically by chromic acid 'oxidation.

With strongly polar species, the anion-exchange affinity increases with decreasing ionic size and with increasing strength of the parent acid. This acid strength effect is more important in sulphate than in phosphate medium. With non-polar species, hydrophobic contributions exert a predominant effect upon the retention volume.

The 10 isomeric naphthalene dicarboxylic acids have been eluted from a column of Dowex 1 anion exchange resin using potassium bromide O-l M. By comparison of their behaviour, it now seems possible that failure to observe these acids in the sub-humic acids of Lawson and co-workers may have been due t
