Sulphate of Diazotoluol , € 7 H 6 N 2 , SH 2 0 4 , 
is obtained in brilliant needles, plates, or prisms, according to the circumstances 
under which it crystallizes. On heating with sulphuric acid in the manner described 
when speaking of the sulphate of diazobenzol, it is converted into a sulpho-acid. 
The barium-salt of this acid crystallizes in long white needles, and is disulpho- 
toluylenate of barium, which, according to the subjoined analysis, has the formula 
© 7 Hg S 2 Ba 2 0 7 . 
0-530 grm. dried at 140° gave 0-276 grm. of sulphate of barium.

Perbromide of Diazotoluol, € 7 H 6 N 2 , HBr, Br 2 , 
is thrown down as a yellow oil, which, after evaporation of the excess of bromine, soli- 
difies to a crystalline mass. 
Platinum-salt of the Hydrochlorate of Diazotoluol , © 7 H 6 N 2 , HC1 Pt Cl 2 , 
is precipitated from a dilute solution of the hydrochlorate of diazotoluol by means of 
bichloride of platinum, and forms fine yellow prisms. When ignited with soda it yields 
an aromatic oil, chlorotoluol (C 7 H 7 Cl). It remains to be seen whether this oil be 
identical, or only isomeric with the chlorobenzyl discovered by Canizzako. 
0-360 grm. of substance gave 0-5765 grm. of carbonic acid and 0-1315 grm. of water. 
0-6305 grm. gave, on ignition with carbonate of sodium, 0-1925 grm. of platinum.

Diazotoluol-amidobenzol, 
1C 6 H 5 (H 2 N). 
This body is obtained by the action of aniline upon nitrate of diazotoluol. It crystal- 
lizes in beautiful long yellow needles. 
DIAZONITEANISOL COMPOUNDS. 
These compounds are nearly related to the diazonitrobenzol-compounds, both with 
regard to physical properties and their deportment with reagents. They are prepared 
also in a similar manner, and it is only necessary therefore to refer respecting their 
preparation to these analogous bodies.
