Q & A
What is the significance of nitroglycerin in the history of explosives?
-Nitroglycerin is significant because it was a thousand times more potent than black powder, the previous dominant explosive. It revolutionized the industry and laid the foundation for modern high explosives.
Who discovered nitroglycerin and under what circumstances?
-Ascanio Sobrero, an Italian chemist, discovered nitroglycerin in 1847 while working at the University of Turin. He combined glycerin with a mixture of nitric acid and sulfuric acid, resulting in a powerful explosive.
What was the initial reaction of Ascanio Sobrero to his discovery of nitroglycerin?
-Ascanio Sobrero was initially shocked and scarred by the explosive power of nitroglycerin when it exploded during his experiment, leaving him with physical scars and a severe headache.
How did nitroglycerin compare to black powder in terms of pressure produced during detonation?
-Nitroglycerin produced 275,000 atmospheres of pressure in microseconds, compared to black powder, which generated 6000 atmospheres over milliseconds, making nitroglycerin significantly more powerful.
What was the role of flash cotton or nitrocellulose in the history of explosives?
-Flash cotton or nitrocellulose was the first plastic explosive discovered and served as an inspiration for Sobrero's discovery of nitroglycerin. It demonstrated the potential of nitro explosives before nitroglycerin was discovered.
How did the chemistry of nitrocellulose differ from that of cellulose?
-Nitrocellulose has the same base structure as cellulose, but each hydroxyl (OH) group in cellulose is transformed into a nitro group, making it highly reactive and capable of burning almost instantly.
What was Alfred Nobel's contribution to the stabilization of nitroglycerin?
-Alfred Nobel discovered that mixing nitroglycerin with Kieselguhr, or diatomite, a porous silica-rich sand, created a stable and easy-to-handle plastic paste, which he named Dynamite.
Why did Alfred Nobel decide to stabilize nitroglycerin?
-Alfred Nobel was deeply affected by the death of his brother Emil in a nitroglycerin factory explosion. This personal tragedy motivated him to find a way to stabilize the explosive and make it safer to use.
What is the legacy of Alfred Nobel beyond the invention of Dynamite?
-Alfred Nobel's legacy includes the establishment of the Nobel Prizes, which recognize achievements in Physics, Chemistry, Physiology or Medicine, Literature, and Peace, using the fortune he amassed from his invention.
How have modern nitro explosives evolved in terms of safety and stability compared to nitroglycerin?
-Modern nitro explosives like TNT and RDX prioritize stability and require a small triggering blast to detonate, making them safer to manufacture and handle compared to the highly sensitive nitroglycerin.
What impact did nitroglycerin have on the development of mega-constructions and the transportation industry?
-Nitroglycerin revolutionized the construction and transportation industries by providing a powerful tool for blasting and excavation, enabling the creation of large-scale infrastructure projects and facilitating the movement of people and goods.

Highlights
Nitroglycerin is a molecule that revolutionized the world as an explosive, being a thousand times more potent than black powder.
Black powder, invented by Chinese alchemists, was the dominant explosive for a thousand years due to its stability and ease of preparation.
Despite its widespread use, black powder had limitations, such as producing a lot of smoke and requiring large amounts for effective explosions.
Ascanio Sobrero, an Italian chemist, discovered nitroglycerin in 1847 by combining glycerin with a mixture of nitric and sulfuric acids.
Nitroglycerin's discovery was accidental and resulted in a violent explosion that scarred Sobrero for life.
The accidental ingestion of nitroglycerin by Sobrero led to the discovery of its medicinal properties, despite its explosive nature.
Nitroglycerin produces 275,000 atmospheres of pressure upon detonation, compared to the 6000 atmospheres of black powder.
Nitrocellulose, discovered by Christian Friedrich Schonbein, was the first plastic explosive and inspired Sobrero's discovery of nitroglycerin.
The fire triangle of nitro explosives is contained within the molecule itself, unlike black powder where each ingredient contributes to one element of the triangle.
Nitrocellulose burns almost instantly due to the fire triangle being present within each molecule, making it a powerful but safe explosive.
Alfred Nobel, after the tragic death of his brother Emil, was determined to stabilize nitroglycerin for safer use in industries.
Kieselguhr, or diatomite, was the key ingredient that Nobel used to stabilize nitroglycerin, creating a plastic paste that was safer to handle.
Dynamite, Nobel's invention, combined the power of nitroglycerin with the safety of a stable explosive, leading to immense industrial and financial success.
The Nobel Prizes, established by Alfred Nobel's will, have recognized contributions to humanity in various fields for over a century.
Modern nitro explosives like TNT and RDX prioritize stability and require a triggering blast for detonation, making them safer to manufacture and handle.
Nitroglycerin's impact on society was profound, enabling the construction of mega-structures and revolutionizing the transport of people and goods.
