Conversion of Benzol-Phenol. 1/ 



Dicarvacrylamine : — 



NfCioHi3 = CooH,6NH. 



The raw, dark-colored, oily, secondary amine was distilled 

 with superheated steam ; the oil which came over in light 

 golden drops and floated on the surface of the milky distillate 

 was extracted with ether, dried over caustic potash and finally 

 redistilled in vacuum. The greater portion distilled at 344°- 

 34'8° ; above this temperature decomposition took place. 

 The fraction so distilling was almost colorless, had a most 

 pleasant odor, dissolved readily in alcohol, ether, and benzol. 

 At — 18° C. the body retained the consistence of an oil. With 

 concentrated sulphuric acid, a golden tint was produced which 

 changed by the addition of a nitrate or nitrite, first, to green- 

 blue, then to blue. 



The analysis gave the following result : — 



I. 0.1856 gr. substance gave 0.5814 gr. carbon-dioxide 

 and 0.1 61 9 gr. water, corresponding to 0.15856 gr. C. and 

 0.01798 gr. H. 



II. 0.2322 gr. substance gave 10.5 cc. of moist nitrogen 

 (thermometer 22° C, barometer 720 mm.) equal to 0.011396 

 gr. N.
