  2. Nitroethane - Wikipedia

    en.wikipedia.org/wiki/Nitroethane

    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.

  3. Self-propagating high-temperature synthesis - Wikipedia

    en.wikipedia.org/wiki/Self-propagating_high...

    Self-propagating high-temperature synthesis (SHS) is a method for producing both inorganic and organic compounds by exothermic combustion reactions in solids of different nature. [1] Reactions can occur between a solid reactant coupled with either a gas, liquid, or other solid.

  4. Exothermic reaction - Wikipedia

    en.wikipedia.org/wiki/Exothermic_reaction

    In thermochemistry, an exothermic reaction is a "reaction for which the overall standard enthalpy change ΔH⚬ is negative." [ 1 ] [ 2 ] Exothermic reactions usually release heat . The term is often confused with exergonic reaction , which IUPAC defines as "... a reaction for which the overall standard Gibbs energy change Δ G ⚬ is negative."

  5. Nef reaction - Wikipedia

    en.wikipedia.org/wiki/Nef_reaction

    In organic chemistry, the Nef reaction is an organic reaction describing the acid hydrolysis of a salt of a primary or secondary nitroalkane (R−NO 2) to an aldehyde (R−CH=O) or a ketone (R 2 C=O) and nitrous oxide (N 2 O). The reaction has been the subject of several literature reviews.

  6. Exothermic process - Wikipedia

    en.wikipedia.org/wiki/Exothermic_process

    An exothermic thermite reaction using iron(III) oxide. The sparks flying outwards are globules of molten iron trailing smoke in their wake. Some examples of exothermic processes are: [14] Combustion of fuels such as wood, coal and oil/petroleum; The thermite reaction [15] The reaction of alkali metals and other highly electropositive metals ...

  7. Blowing agent - Wikipedia

    en.wikipedia.org/wiki/Blowing_agent

    Gaseous products and other byproducts are formed by a chemical reaction of the chemical blowing agent, promoted by the heat of the foam production process or a reacting polymer's exothermic heat. Since the blowing reaction occurs forming low molecular weight compounds acting as the blowing gas, additional exothermic heat is also

  8. Thermochemistry - Wikipedia

    en.wikipedia.org/wiki/Thermochemistry

    Thermochemistry is the study of the heat energy which is associated with chemical reactions and/or phase changes such as melting and boiling.A reaction may release or absorb energy, and a phase change may do the same.

  9. Nitro compound - Wikipedia

    en.wikipedia.org/wiki/Nitro_compound

    Chloramphenicol is a rare example of a naturally occurring nitro compound. At least some naturally occurring nitro groups arose by the oxidation of amino groups. [17] 2-Nitrophenol is an aggregation pheromone of ticks. Examples of nitro compounds are rare in nature. 3-Nitropropionic acid found in fungi and plants .
