steam. By this means a light golden oil was obtained, 

 which became colorless after distillation in an atmosphere 

 of hydrogen. A small portion distilled over at 290°-305°, a 

 greater amount between 305°-3i5°; at 315° partial decompo- 

 sition took place, yellowish white fumes were given off. 

 (Under similar conditions diphenylamine boiled at 297°.) 



An analysis of the portion distilling between 305°-3i5° 

 gave the following result : — 



I. 0.2176 gr. substance gave 0.6793 gr. carbon-dioxide and 

 0.183 gr. water, corresponding to 0.18525 gr. C. and 0.02033 

 gr. H. 



II. 0.1642 gr. substance gave 8 cc. of moist nitrogen (ther- 

 mometer 20° C, barometer 760 mm.) equal to 0.0090632 gr. N. 



III. 0.2737 gr. substance gave 13 cc. of moist nitrogen (ther- 

 mometer 21° C, barometer 726 mm.) equal to 0.0141 2 19 gr. N.

I was unable to obtain the base other than as a thick oil 

 even at temperature of — 1 5° C. A drop of nitric acid added 

 to the light yellow-brown solution of diphenisobutylamine in 

 concentrated sulphuric acid, produced a violet tint which 

 changed rapidly to blue and then to blue-black. 



Finally, the unchanged phenol separated from the first 

 ether extract was again set free by hydrochloric acid, isolated 

 with ether, and distilled at 229°-233°. The investigations 

 proved that in its qualitative aspects, at least, isobutylphenol 

 is analogous to benzol-phenol, the cresols and the xylenes. 

 The results of repeated experiments have shown that a better 

 yield of primary and secondary amines is obtained by the 

 action of zinc-ammonium-bromide than with Zfinc-ammonium-
