Nitromethane is used as a fuel in motor racing, particularly drag racing, as well as for radio-controlled model power boats, cars, planes and helicopters. In this context, nitromethane is commonly referred to as "nitro fuel" or simply "nitro", and is the principal ingredient for fuel used in the "Top Fuel" category of drag racing. [14]
1-nitropropane is produced industrially by the reaction of propane and nitric acid. This reaction forms four nitroalkanes: nitromethane, nitroethane, 1-nitropropane, and 2-nitropropane. 1-nitropropane is also a byproduct of the process for making 2-nitropropane, which is done by vapour phase nitration of propane.
The pK a values of nitromethane and 2-nitropropane are respectively 17.2 and 16.9 in dimethyl sulfoxide (DMSO) solution, suggesting an aqueous pK a of around 11. [22] In other words, these carbon acids can be deprotonated in aqueous solution. The conjugate base is called a nitronate, and behaves similar to an enolate.
This exothermic reaction produces four industrially significant nitroalkanes: nitromethane, nitroethane, 1-nitropropane, and 2-nitropropane. The reaction involves free radicals, such as CH 3 CH 2 CH 2 O., which arise via homolysis of the corresponding nitrite ester. These alkoxy radicals are susceptible to C—C fragmentation reactions, which ...
For the first time in two decades, the Food and Drug Administration (FDA) has approved a new class of medication that provides an alternative to addictive opioids for patients looking to manage ...
3. Lifestyle Changes. Along with oral and topical medications, lifestyle changes also can often help put the brakes on a receding hairline and even trigger some new hair growth.

Treatment of aromatic nitro compounds with metal hydrides gives good yields of azo compounds. For example, one could use: Lithium aluminium hydride [20] Zinc metal with sodium hydroxide. [19] (Excess zinc will reduce the azo group to a hydrazino compound.)
