I. — On the Conversion of Some of the Homologues 



of Benzol-Phenol into Primary and 



Secondary Amines. 



By RACHEL LLOYD. 



Various experiments, attended with but little or no suc- 

 cess, have been made by distinguished chemists at different 

 periods of time to convert benzol-phenol into aniline. 



Some years since, Professor V. Merz and W. Weith ^ 

 obtained aniline, together with diphenylamine, by heating 

 benzol-phenol and zinc-ammonium-chloride at a temperature 

 of 280-300°. Later experiments, made in the laboratory 

 of Professor Merz^ have shown that the above-mentioned 

 changes take place more readily when ammonium-chloride is 

 added to the zinc-ammonium-chloride and the temperature 

 raised to 330°. Under these conditions, the three cresols 

 have been converted into the corresponding mono- and dito- 

 lylamines, as well as the xylenes into primary and secondary 

 amines. It has been further proved that zinc-ammonium- 

 bromide and ammonium-bromide produce similar results 

 to those given by zinc-ammonium-chloride and ammonium- 

 chloride.
