Abstract
Abstract n-Pentyl-2-pyridyl ketoxime hydrochloride has been prepared and examined as a colorimetric reagent for copper. It is less sensitive than some reagents, but shows a remarkable selectivity toward copper. The copper(I) -oxime compound can be extracted into isoamyl alcohol or into chloroform. In isoamyl alcohol the colored compound conforms to Beer's law in concentrations up to 5.6 · 10-4M and has a molar absorptivity of 2650 at 360 mμ. A procedure for the colorimetric determination of copper is given and its reliability is shown.
