Die Farbreaktion der Phenole mit dem Chlor/<i>o</i>‐Tolidin‐Reagens

Abstract

Abstract Phenols produce colours with chlorine/ o ‐tolidine, a method usually applied for the detection of NH‐groups. A series of phenols has been tested and the results are compared with standard tests for phenols. The procedure described is particularly suitable for spray reagents in paper and thin layer chromatography.
