The differences in reactivity of these halides make available compounds bearing two different amine substituents. Nitration of aldehyde 104, followed by oxidation affords the acid 106. The acid is then converted to the primary amide (107), and the nitro group is reduced catalytically to the corresponding... 

Nitrations of aromatic amines often involve the intermediate formation of N-nitramines, although these are rarely seen under the strongly acidic conditions of mixed acid nitration (Section 4.5). N,2,4,6-Tetranitro-N-methylaniline (tetryl) is an important secondary high explosive usually synthesized from the nitration of N,N-dimethylaniline or 2,4-dinitro-N-methylaniline. ° The synthesis of tetryl is discussed in Section 5.14.

TNT 7.5, Al dust 0.5, coal 3 and chalk 0.5%. The introduction of up to 10% of hydrazine nitrate in an AN expl markedly increases sensitivity and deton rate. AN and hydrazine nitrate are prefetbably mixed together prior to the addition of other ingredients, or they may be fused, solidified and subdivided prior to such addition (Ref 80) k)An expl obtai ned by neutralization of an acidic nitrated polyol such as NG by the addition of amines or amides such as urea, especially i n the form of a melt with AN i n a eutectic mixt. The expl is stable i n storage, especially when the amine or amide is present in excess(Ref 87)... 

Nitric acid not only nitrates, but oxidizes the highly reactive ring as well, with loss of much material as tar. Furthermore, in the strongly acidic nitration medium, the amine is converted into the anilinium ion substitution is thus controlled not by the —NH2 group but by the NH3 group which, because of its positive charge, directs much of the substitution to the meta position.

ACRYLIC ACID, 2-ETHYLHEXYL-ESTER (103-11-7) CnHjoOj Combustible liquid. Forms explosive mixture with air [explosion limits in air (vol %) 0.8 to 6.4 flashpoint 180°F/82°C oc autoignition temp 496°F/258°C Fire Rating 2]. Unless inhibited, contact with heat, sunlight, contaminants, or peroxides may cause hazardous polymerization. Reacts violently ivith strong oxidizers, with risk of fire and explosions. Incompatible with strong acids, alkalis, aliphatic amines, alkanolamines, nitrates. The uninhibited monomer vapor may block vents and confined spaces by, forming a solid polymer material. On small fires, use AFFF, foam, dry chemical, or COj extinguishers.
