  2. 1-Nitropropane - Wikipedia

    en.wikipedia.org/wiki/1-Nitropropane

    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.

  3. Nitroethane - Wikipedia

    en.wikipedia.org/wiki/Nitroethane

    Nitroethane is produced industrially by treating propane with nitric acid at 350–450 °C. 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 ...

  4. Nitro compound - Wikipedia

    en.wikipedia.org/wiki/Nitro_compound

    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).

  5. Water-reactive substances - Wikipedia

    en.wikipedia.org/wiki/Water-reactive_substances

    Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .

  6. Azeotrope tables - Wikipedia

    en.wikipedia.org/wiki/Azeotrope_tables

    This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

  7. Dilution (equation) - Wikipedia

    en.wikipedia.org/wiki/Dilution_(equation)

    Dilution is the process of decreasing the concentration of a solute in a solution, usually simply by mixing with more solvent like adding more water to the solution. To dilute a solution means to add more solvent without the addition of more solute. The resulting solution is thoroughly mixed so as to ensure that all parts of the solution are ...

  8. 1,4-Dioxane - Wikipedia

    en.wikipedia.org/wiki/1,4-Dioxane

    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 ...

  9. Enthalpy of neutralization - Wikipedia

    en.wikipedia.org/wiki/Enthalpy_of_neutralization

    as the acid and the base are fully dissociated and neither the cation B + nor the anion A − are involved in the neutralization reaction. [1] The enthalpy change for this reaction is -57.62 kJ/mol at 25 °C. For weak acids or bases, the heat of neutralization is pH-dependent. [1] In the absence of any added mineral acid or alkali, some heat is ...
