19. Interaction of Hydrazine Sulphate 
with Nitrites, and a new method for the determination of 
“ Nitritic’’ Nitrogen.

Consequent upon the discovery of the unstable alkylamine 
nitrites (vide Trans. Chemical Society 1911) by Ray and Raks- 
hit, we undertook the preparation, if possible, of the nitrites 
of Hydrazine and Hydroxylamine which are strong bases. 
The possibility of a hydrazine nitrite was further strengthened 
by the existence of a dithionate of the same base which has 
been described by Sabanieff (Journ. Chem. Soc. 1899, Ab- 
stracts, Part II, page 364). Accordingly, we tried to prepare 
the salt by a double decomposition between Barium-Nitrite 
and Hydrazine Sulphate. On mixing the solutions of the two 
substances there was immediate precipitation of Barium 
cold, which readily decomposes with the rise of temperature. 
The isolation of the pure nitrite had therefore to be given up, 
and our attention was directed to a systematic examination of 
the gases evolved, hoping thereby to gain some information as 
to the nature of the reactions occurring. It was at first sup- 
posed that the nitrous acid liberated would act upon the 
Hydrazine or amido-amine, in the same manner as it does with 
ammonia or amines, the reaction proceeding according to the 
following equation. 
H.NH,+HO.NO = H.OH +N,+H_0.

It would appear from the above that the reaction would 
be accompanied by the formation of hydrogen peroxide in 
solution, and a regular search was therefore made for the 
latter. On applying the ether-chromic acid and titanium solu-
