The authors tried to purify three kinds of phenols (Phenol from distillation of coaltar, Phenol from sulfonation of benzene, Phenol from cumen) by the zone melting method. Three samples were zone-purified through 20 zone passes. Each fraction (one zone length) of the individual sample was determined by refractive index, infrared spectrometry and qualitative test by thin-layer Chromatography.
