✦ Synopsis


In part I of this series .l, the determination of the ultraviolet al)sorption spectra in cyclohcxanc solution of a number of methyl aryl ethers was described.

'I'llcse compounds, by virtue of their charactcristic spectra may be readily recognized, and if present together, may he sepratcd by cltltion chromatography on suitilblc rllumina columns2.
