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 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).
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 ...
A salt metathesis reaction is a chemical process involving the exchange of bonds between two reacting chemical species which results in the creation of products with similar or identical bonding affiliations. [1] This reaction is represented by the general scheme: + +
The salt KHSO 5 is often referred to as oxone, but they are not the same. Oxone refers to the triple salt 2KHSO 5 ·KHSO 4 ·K 2 SO 4, which is more shelf-stable than KHSO 5. [16] Epoxidations using isolated dioxirane (e.g. DMD or TFD) avoid the need for aqueous buffering. The volatile dioxiranes DMD and TFD can be isolated via distillation.
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% ...

While the FDA encourages manufacturers to remove 1,4-dioxane, it is not required by federal law. [29] On 9 December 2019, New York passed a bill to ban the sale of cosmetics with more than 10 ppm of 1,4-dioxane as of the end of 2022. The law will also prevent the sale of household cleaning and personal care products containing more than 2 ppm ...
