実験手順

N,N'-bis(3-hexylundecyl)pyridine-2,5-dicarboxamide was prepared using the method of Example 1 from 3-hexylundecylamine and pyridine 2,5-dicarboxylic acid. The product which was a brown oil was not distilled but was analysed as being 92% of theoretical strength (based on MW 642) by titration of an aliquot in acetic acid with perchloric acid. It was made up as a 0.2M solution in AROMASOL H and tested for extraction of copper in the presence of chloride ion using the method of Examples 6 and 7. The results are given in Table 3. They indicated that this compound is a strong extractant for copper which would be best employed in extracting copper from solutions of relatively low chloride ion concentration and relatively low acidity.
