  2. Colored fire - Wikipedia

    en.wikipedia.org/wiki/Colored_fire

    Generally, the color of a flame may be red, orange, blue, yellow, or white, and is dominated by blackbody radiation from soot and steam. When additional chemicals are added to the fuel burning, their atomic emission spectra can affect the frequencies of visible light radiation emitted - in other words, the flame appears in a different color ...

  3. Nitromethane - Wikipedia

    en.wikipedia.org/wiki/Nitromethane

    Pure nitromethane is an insensitive explosive with a VoD of approximately 6,400 m/s (21,000 ft/s), but even so inhibitors may be used to reduce the hazards. The tank car explosion was speculated [citation needed] to be due to adiabatic compression, a hazard common to all liquid explosives. This is when small entrained air bubbles compress and ...

  4. Nitro compound - Wikipedia

    en.wikipedia.org/wiki/Nitro_compound

    Explosive decomposition of organo nitro compounds are redox reactions, wherein both the oxidant (nitro group) and the fuel (hydrocarbon substituent) are bound within the same molecule. The explosion process generates heat by forming highly stable products including molecular nitrogen (N 2), carbon dioxide, and water. The explosive power of this ...

  5. CPK coloring - Wikipedia

    en.wikipedia.org/wiki/CPK_coloring

    Several of the CPK colors refer mnemonically to colors of the pure elements or notable compound. For example, hydrogen is a colorless gas, carbon as charcoal, graphite or coke is black, sulfur powder is yellow, chlorine is a greenish gas, bromine is a dark red liquid, iodine in ether is violet, amorphous phosphorus is red, rust is dark orange-red, etc.

  6. PLX - Wikipedia

    en.wikipedia.org/wiki/PLX

    PLX has been implicated as one of the materials capable of being used in catastrophic terrorism, as most steel core columns can not withstand the detonation of 10 – 30 kg PLX in direct contact (explosive on bare steel). Nitromethane and its gelling agents are freely sold to the public in the US, though.

    Division 1.1: Substances and articles which have a mass explosion hazard Division 1.2: Substances and articles which have a projection hazard but not a mass explosion hazard Division 1.3: Substances and articles which have a fire hazard and either a minor blast hazard or a minor projection hazard or both, but not a mass explosion hazard

  8. Flame - Wikipedia

    en.wikipedia.org/wiki/Flame

    Here the red color compared to typical yellow color of the flames suggests that the temperature is lower. This is because there is a lack of oxygen in the room and therefore there is incomplete combustion and the flame temperature is low, often just 600 to 850 °C (1,112 to 1,562 °F).

  9. Tetranitromethane - Wikipedia

    en.wikipedia.org/wiki/Tetranitromethane

    TNM is a pale yellow liquid that can be prepared in the laboratory by the nitration of acetic anhydride with anhydrous nitric acid (Chattaway's method). [8] This method was attempted on an industrial scale in the 1950s by Nitroform Products Company in Newark, USA, but the entire plant was destroyed by an explosion in 1953.
