The analysis confirmed the presence of a secondary 

 amine : — 



I. 0.2529 gr. substance gave 0.7925 gr. carbon dioxide 

 and 0.2350 gr. water, equal to 0.2 161 3 gr. C. and 0.0261 1 

 gr. H. 



II. 0.2291 gr. substance gave 10 cc. of moist nitrogen 

 (thermometer 22° C. barometer 729 mm.) equal to 0.010854 



gr. N. 



Calculated for 

 C22H31N. 



C22 — 264 — 85.44 per cent 

 H31— 31— 10.03 



N - 14- 4.53

Upon standing, the amine became darker in color, and in 

 concentrated sulphuric acid dissolved with an exquisite 

 golden color which grew darker in the air ; the addition of a 

 nitrite or of nitric acid to this solution changed the color, 

 first to light violet, then to a deep blue. In connection 

 with these bases, a considerable quantity of unchanged phenol 

 was found, which was isolated and distilled. Boiling point, 

 247°-250°. 



The results of corresponding experiments with the bromides 

 and chlorides of zinc and ammonium are here tabulated. 

 Temperature, 330°-340° ; time, forty hours.
