The reaction has been the subject of several literature reviews. [1] [2] [3] The Nef reaction: 1. Salt of a nitroalkane 3. Ketone 4. Nitrous oxide. The reaction was reported in 1894 by the chemist John Ulric Nef, [4] who treated the sodium salt of nitroethane with sulfuric acid resulting in an 85–89% yield of nitrous oxide and at least 70% ...
Nitroethane is an organic compound having the chemical formula C 2 H 5 NO 2. Similar in many regards to nitromethane , nitroethane is an oily liquid at standard temperature and pressure. Pure nitroethane is colorless and has a fruity odor.
Nitromethane reacts with solutions of sodium hydroxide or methoxide in alcohol to produce an insoluble salt of nitromethane. This substance is a sensitive explosive which reverts to nitromethane under acidic conditions and decomposes in water to form another explosive compound, sodium methazonate, which has a reddish-brown color:
The gas phase reaction between dilute F 2 and HN 3 produces FN 3. [44] [45] Chlorine azide, also a gas, can be produced from passing chlorine gas through a solution of NaN 3. [46] Chlorine azide tends to explode spontaneously even at reduced temperatures. Bromine azide is a liquid but is also treacherous. [46] BrN 3 hydrolyzes readily.
The reaction produces fragments from the parent alkane, creating a diverse mixture of products; for instance, nitromethane, nitroethane, 1-nitropropane, and 2-nitropropane are produced by treating propane with nitric acid in the gas phase (e.g. 350–450 °C and 8–12 atm).
Can we imagine ourselves back on that awful day in the summer of 2010, in the hot firefight that went on for nine hours? Men frenzied with exhaustion and reckless exuberance, eyes and throats burning from dust and smoke, in a battle that erupted after Taliban insurgents castrated a young boy in the village, knowing his family would summon nearby Marines for help and the Marines would come ...
Getting a good night's sleep can be a little more challenging amid the hype of the holidays. With changes in routine, diet and potentially time zones, quality sleep could be difficult to come by ...
