The Woolwich process was expensive: it needed 11 pounds (5.0 kg) of strong nitric acid for every pound of RDX. [49] By early 1941, the NDRC was researching new processes. [49] The Woolwich or direct nitration process has at least two serious disadvantages: (1) it used large amounts of nitric acid and (2) at least one-half of the formaldehyde is ...
RDX is a widely used explosive material that is produced by the nitrolysis reaction of hexamine. Nitrolysis is a chemical reaction involving cleavage ("lysis") of a chemical bond concomitant with installation of a nitro group (NO 2). Typical reagents for effecting this conversion are nitric acid and acetyl nitrate.
HMX is more complicated to manufacture than most explosives, and this confines it to specialist applications. It and RDX are both produced by the Bachmann process—nitration of hexamine using a mixture of ammonium nitrate and nitric acid in a mixture of acetic acid and acetic anhydride as solvent—with the major product determined by the specific reaction conditions.
Esbit's Safety Data Sheet states combustion can create formaldehyde, ammonia, nitrogen oxide, hydrogen cyanide and ingestion may cause nausea, vomiting, gastrointestinal disturbances, and kidney damage. When burned, the chemical oxidation of the fuel yields noxious fumes, which requires cooking foods in a container, such as a pot or pan, with a ...
A solution of nitric acid, water and alcohol, nital, is used for etching metals to reveal the microstructure. ISO 14104 is one of the standards detailing this well known procedure. [45] Nitric acid is used either in combination with hydrochloric acid or alone to clean glass cover slips and glass slides for high-end microscopy applications. [46]
Red fuming nitric acid (RFNA) is a storable oxidizer used as a rocket propellant. It consists of nitric acid ( H N O 3 ), dinitrogen tetroxide ( N 2 O 4 ) and a small amount of water . The color of red fuming nitric acid is due to the dinitrogen tetroxide, which breaks down partially to form nitrogen dioxide .
n.o.s. = not otherwise specified meaning a collective entry to which substances, mixtures, solutions or articles may be assigned if a) they are not mentioned by name in 3.2 Dangerous Goods List AND b) they exhibit chemical, physical and/or dangerous properties corresponding to the Class, classification code, packing group and the name and description of the n.o.s. entry [2]
Organyl derivatives of nitramide, R−NH−NO 2 and R 2 N−NO 2, are widely used as explosives: examples include RDX and HMX. It is an isomer of hyponitrous acid. Nitramide can be viewed as a nitrogen analog of nitric acid (HO−NO 2), in which the hydroxyl group −OH is replaced with the amino group −NH 2.
