Chemical Properties
green crystalline powder
Uses
N,N-Diethyl-4-nitrosobenzenamine reacts with rubber to form a compound that acts as efficient antioxidants.
General Description
Green solid. Insoluble in water.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
A nitrated amine. Amines are combustible. The combustion of amines yields noxious NOx. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. Aromatic nitro compounds range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. The aromatic nitro compounds may explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water or organic solvents. The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups.
Safety Profile
Mutation data reported. When heated to decomposition it emits toxic vapors of NOx.
Check Digit Verification of cas no
The CAS Registry Mumber 120-22-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 120-22:
(5*1)+(4*2)+(3*0)+(2*2)+(1*2)=19
19 % 10 = 9
So 120-22-9 is a valid CAS Registry Number.

Nitrosation of arenes with nitrosonium ethyl sulfate
Zyk,Nesterov,Khlobystov,Zefirov
, p. 506 - 509 (1999)
Nitrosonium ethyl sulfate reacts with O-alkylphenols and N,N-dialkylanilines to give the corresponding 4-nitrosoarenes. The reaction is not accompanied by side processes characteristic of common nitrosating agents. Diazotization of primary aromatic amines with nitrosonium ethyl sulfate yields stable diazonium salts, which are promising reagents for organic synthesis.
NO2/H3BO3 as an effective nitrosonium source for electrophilic aromatic nitrosation under MW-promoted solvent-free conditions
Valizadeh, Hassan,Gholipour, Hamid
experimental part, p. 963 - 966 (2012/04/23)
[Bmim]NO2/H3BO3 was used as a nitrosonium source for the efficient synthesis of nitrosoarenes. The reaction was accomplished under MW irradiation at 60 W in a solventless system. Side processes such as oxidation or dealkylation were not observed during the nitrosation of alkyl phenyl ethers in the presence of this new reagent. The satisfactory results were obtained with very short reaction time, simplicity in the experimental procedure and good to excellent yields.
