Art. L. — On a Base derived from a Waste-product in the Aniline 

 Manufacture; by C. Loring Jackson. 



In the spring of 1875 under the direction of Prof. A. W. 

 Hofmann I investigated a waste-product from the factory of 

 Drs. Martius and Mendelssohn-Bartholdy at Eummelsburg near 

 Berlin, which was obtained after the toluidine had passed over 

 in the annual rectification of the highest fractions from the 

 n. The results I then obtained were pub- 

 lished in the Berichte der Deutschen Chemischen Gesellschaft 

 for 1875, page 968, and may be briefly restated as follows by 

 way of introduction to my subsequent work. 



The substance, a black oily liquid, was dissolved in strong 

 hydrochloric acid, and freed from tar by repeated filtration ; 

 the oily base set free by sodic hydrate was" then fractioned, and 

 yielded at first xylidine and allied bodies which were not 

 further examined; later a fraction from 280° to 320° which, 

 after removal of naphtylamine with dilute sulphuric acid, was 

 converted into a nitrate and purified by crystallization ; it then 

 formed radiated groups of white needles which gave on

By heating with nitric acid a magenta-colored substance. was 

 formed which rendered it very difficult to obtain the salt white. 

 The sulphate was very soluble. 



The chloride C, ,H, 4 NC1 crystallized in white flat needles. 



The platinum salt (C, 3 H, 4 N) 3 PtCl 6 crystallized in very 



characteristic fan-like groups of sparingly soluble light yellow 



needles often more than half a centimeter long. The analysis 



gave

The free base C, 3 H, 3 N was obtained as an oil which gave 

 reform and potassic hydrate a smell similar to that of 

 the isocyanides ; it was therefore a primary amine, and its form- 

 ula must be written C, ,H. ,NH 3 . 



An acet-compound C, 3 H, ,NHC 2 H 3 was also prepared by 

 the action of aeetyl-ehloride on the free base ; it crystallized m 

 white needles and melted at 114° 25. At that time also some 

 attempts were made to obtain synthetically a base with the 

 same formula, but the results were not published.
