2-Nitrochlorobenzene is an organic compound with the formula ClC 6 H 4 NO 2. It is one of three isomeric nitrochlorobenzenes . [ 1 ] It is a yellow crystalline solid that is important as a precursor to other compounds due to its two functional groups.
The Birkeland–Eyde process was one of the competing industrial processes in the beginning of nitrogen-based fertilizer production. It is a multi-step nitrogen fixation reaction that uses electrical arcs to react atmospheric nitrogen (N 2) with oxygen (O 2), ultimately producing nitric acid (HNO 3) with water. [1]
Mixed oxides of nitrogen (MON) are solutions of dinitrogen trioxide (N 2 O 3) in dinitrogen tetroxide/nitrogen dioxide (N 2 O 4 and NO 2). It may be used as an oxidizing agent in rocket propulsion systems. [1] Mixed oxides of nitrogen are produced by dissolving nitric oxide (NO) gas in liquid dinitrogen tetroxide. Nitric oxide reacts with ...
Due to relatively weak N–O bonding, all nitrogen oxides are unstable with respect to N 2 and O 2, which is the principle behind the catalytic converter, and prevents the oxygen and nitrogen in the atmosphere from combusting.
Nitrochlorobenzene is typically synthesized by nitration of chlorobenzene in the presence of sulfuric acid: C 6 H 5 Cl + HNO 3 → O 2 NC 6 H 4 Cl + H 2 O. This reaction affords a mixture of isomers. Using an acid ratio of 30/56/14, the product mix is typically 34-36% 2-nitrochlorobenzene and 63-65% 4-nitrochlorobenzene, with only about 1% 3 ...

Nitrogen enters the ocean through precipitation, runoff, or as N 2 from the atmosphere. Nitrogen cannot be utilized by phytoplankton as N 2 so it must undergo nitrogen fixation which is performed predominantly by cyanobacteria. [82] Without supplies of fixed nitrogen entering the marine cycle, the fixed nitrogen would be used up in about 2000 ...
The 1,000th Wordle puzzle ran in March, a milestone for the popular game where players tend to stick to a formula, with 2.8 million people using the same starting word every day as proof. The most ...
