  2. Pyrophoricity - Wikipedia

    en.wikipedia.org/wiki/Pyrophoricity

    The creation of sparks from metals is based on the pyrophoricity of small metal particles, and pyrophoric alloys are made for this purpose. [2] Practical applications include the sparking mechanisms in lighters and various toys, using ferrocerium; starting fires without matches, using a firesteel; the flintlock mechanism in firearms; and spark testing ferrous metals.

    en.wikipedia.org/wiki/Pyrotechnic_composition

    A pyrotechnic composition is a substance or mixture of substances designed to produce an effect by heat, light, sound, gas/smoke or a combination of these, as a result of non-detonative self-sustaining exothermic chemical reactions. Pyrotechnic substances do not rely on oxygen from external sources to sustain the reaction.

  7. Diborane - Wikipedia

    en.wikipedia.org/wiki/Diborane

    As a pyrophoric substance, diborane reacts exothermically with oxygen to form boron trioxide and water: 2 B 2 H 6 + 6 O 2 → 2 B 2 O 3 + 6 H 2 O (ΔH r = −2035 kJ/mol = −73.47 kJ/g) Diborane reacts violently with water to form hydrogen and boric acid: B 2 H 6 + 6 H 2 O → 2 B(OH) 3 + 6 H 2 (ΔH r = −466 kJ/mol = −16.82 kJ/g) Diborane ...

  8. Anthocyanin - Wikipedia

    en.wikipedia.org/wiki/Anthocyanin

    Although approved as food and beverage colorant in the European Union, anthocyanins are not approved for use as a food additive because they have not been verified as safe when used as food or supplement ingredients. [4] There is no conclusive evidence that anthocyanins have any effect on human biology or diseases. [4] [5] [6]

  9. Naturally occurring phenols - Wikipedia

    en.wikipedia.org/wiki/Naturally_occurring_phenols

    The hardening of the protein component of insect cuticle has been shown to be due to the tanning action of an agent produced by oxidation of a phenolic substance forming sclerotin. [ citation needed ] In the analogous hardening of the cockroach ootheca , the phenolic substance concerned is 3:4-dihydroxybenzoic acid ( protocatechuic acid ).
