Benzamide has been made to undergo Hofmann rearrangement, in the presence of hypochlorite (OCl‐) generated in situ, by the electrolysis of sodium chloride solution using platinised titanium anode and graphite cathode. The product is not a pure primary amine, namely aniline; but a polymeric aniline derivative is produced. It has a free amino end; and/or a free amino end is generated during the process of diazotisation. The product has been diazotised and coupled with naphthols to give dyes. The nature of the dyes have been analysed by uv‐visible spectral studies. The dyes are slightly different from the dyes prepared from pure aniline.

Aqueous sodium chloride solution, containing benzamide was electrolysed (pH = 2), using platinised titanium anode and graphite cathode. The filtrate of the reaction mixture (pH = 4.5) was diazotised and coupled with α‐naphthol in NaOH and also with β‐naphthol in NaOH. Dyes were produced. These dyes were matched with the standard dyes prepared from aniline. Uv‐visible absorption spectral study reveals that the dyes produced are slightly different from the standard dyes. During the course of the reaction benzamide is converted into aniline with a long chain polymeric unit having a free amino end; and/or a polymeric unit which generates a free amino end during the process of diazotisation.

A light yellow luminescence is emitted when an adhesive binding two sheets of paper is stretched. The adhesive present on the paper is found to be fluorescent. The paper, even without the adhesive, is found to be fluorescent. The fluorescent nature of the materials has been confirmed by fluorescence spectra.
