Interesting Facts about Nitroglycerin

Facts:
The explosion of nitroglycerine forms up to 275000 atm in the matter of microseconds.
C3H5O9 (l)    à   1.5 N2 (g)    +    2.5 H2O (g)    +    3 CO2 (g)    +    0.25 O2 (g)
1 mole of nitroglycerin forms 7.25 moles of gas.

      It is very explosive and unstable, so it explodes when heated up or put under pressure. However, it's not so unstable when mixed with a clay called kieselguhr, forming dynamite

In Medication:
      Nitroglycerin pills help prevent chest pain caused by low blood flow. The nitroglycerin is converted into nitric oxide, which decrease chest pain, increase heart rate and dilate blood vessels to allow more flow and lower the blood pressure. Some side effects of using nitroglycerin medication include: low blood pressure causing dizziness, massive headache, weakening of limbs, painful urination and increased bowel movements.

In Industry
       Nitroglycerin was most commonly used for mining. Transportation of the substance soon became outlawed due to unexpected explosions, so much of the nitroglycerine needed to be used for blasting was instead made on-site. In the past, nitroglycerin was used to clear blocked oil wells. Nitroglycerin was also used to demolish buildings. In the past, there was not very good technology for special effects in movies, so many directors of old films utilized dynamite in many movies!
