Ethyl nitrate is the ethyl ester of nitric acid and has the chemical formula C 2 H 5 N O 3.It is a colourless, volatile, explosive, and extremely flammable liquid. It is used in organic synthesis with use as a nitrating agent and as an intermediate in the preparation of some drugs, dyes, and perfumes. [1]
The OSHA definition is arguably broad enough to include oxygen-deficient circumstances in the absence of "airborne contaminants", as well as many other chemical, thermal, or pneumatic hazards to life or health (e.g., pure helium, super-cooled or super-heated air, hyperbaric or hypo-baric or submerged chambers, etc.).
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]
2 O entering the atmosphere is the result of human activity, [68] control of nitrous oxide is part of efforts to curb greenhouse gas emissions. [ 130 ] Most human caused nitrous oxide released into the atmosphere is a greenhouse gas emission from agriculture , when farmers add nitrogen-based fertilizers onto the fields, and through the ...
In organic chemistry, a nitrate ester is an organic functional group with the formula R−ONO 2, where R stands for any organyl group. They are the esters of nitric acid and alcohols . A well-known example is nitroglycerin , which is not a nitro compound, despite its name.
High-temperature flame with solid particles, which interfere with flame colorants. Reacts with nitrates, except ammonium nitrate, yielding nitrogen oxides, ammonia, and heat (the reaction is slow at room temperature but violent at above 80 °C and may spontaneously ignite); the reaction can be inhibited by a weak acid, e.g. boric acid. Corroded ...
These are thought to be the principal pathways for formation of nitric acid in the atmosphere. [8]: 224–225 This nitric acid contributes to acid rain or may deposit to soil, where it makes nitrate, which is of use to growing plants. The aqueous phase reaction 2 NO 2 + H 2 O → HNO 2 + HNO 3. is too slow to be of any significance in the ...
Peroxyacetyl nitrate (C 2 H 3 NO 5): formed from NO x and VOCs, like ozone. Photochemical smog: particles are formed from gaseous primary contaminants and chemicals. [96] Smog is a type of pollution that occurs in the atmosphere. Smog is caused by a huge volume of coal being burned in a certain region, resulting in a mixture of smoke and sulfur ...
