How was the nitroglycerin made more stable?
Dynamite was invented by Alfred Nobel in 1866. Nitroglycerin, a very unstable explosive, was already known. Nobel mixed the nitroglycerin with silica to stabilize it and form a solid material.
What neutralizes nitroglycerin?
In its purest form, nitroglycerin has a rather unique chemical structure that leads to it being extremely unstable and dangerous to handle. 9 percent sodium chloride solution or five percent glucose solution, and this neutralizes the unstable and explosive effects of the nitroglycerin.
What is used to make nitroglycerin?
Nitroglycerin is an explosive compound formed by the combination of glycerol and nitric and sulfuric acids. It was first synthesized in 1864 by chemist Ascanio Sobrero, who destroyed his notes for fear of the damage his highly unstable discovery might cause.
How was nitroglycerin made?
Nitroglycerine is an explosive liquid which was first made by Ascanio Sobrero in 1846 by treating glycerol with a mixture of nitric and sulphuric acid. He made one of his most important discoveries when he found that by mixing nitroglycerine, an oily fluid, with kieselguhr, the mixture could be turned into a paste.
How is nitroglycerin volatile?
Nitroglycerin is a powerful and unstable explosive that Alfred Nobel used in his invention of dynamite in the mid 1800s. Being a volatile liquid, fumes of nitroglycerin were constantly inhaled by workers in the dynamite factories in Stockholm. The result of this inhalation was two-fold.
What makes nitroglycerin so volatile?
An Explosive Combination of Atoms Nitroglycerin is an oily, colourless liquid, but also a high explosive that is so unstable that the slightest jolt, impact or friction can cause it to spontaneously detonate. It is the speed of the decomposition reaction which makes nitroglycerin such a violent explosive.
How is nitroglycerin administered?
Nitroglycerin comes as a sublingual tablet to take under the tongue. The tablets is usually taken as needed, either 5 to 10 minutes before activities that may cause attacks of angina or at the first sign of an attack.
Why is nitroglycerin so sensitive?
You can see that 4 moles of nitroglycerin produces 35 moles of hot gases. The concentrated gases are under very high pressure, so they expand rapidly. The heat speeds up the individual gas particles, boosting the pressure even higher. The gas expands faster than the speed of sound, it generates a powerful shock wave.
Who improved the handling of nitroglycerin?
Nitroglycerin is a powerful and unstable explosive that Alfred Nobel used in his invention of dynamite in the mid 1800s. Nobel developed this easily handled explosive to great benefit in his heavy construction businesses (roads, tunnels, etc.).
How do you administer nitro?
Place the tablet under the tongue or between the cheek and gum, and let it dissolve. Do not eat, drink, smoke, or use chewing tobacco while a tablet is dissolving. Nitroglycerin sublingual tablets usually give relief in 1 to 5 minutes.
Why was nitroglycerin so unstable?
The reason nitrogen triiodide is so unstable is down to its molecular structure – one nitrogen atom and three iodine molecules all on one side due to how the nitrogen’s electrons are arranged.
How did Alfred Nobel invent nitroglycerin as an explosive?
Nitroglycerin is an oily liquid that may explode when subjected to heat, shock, or flame. Alfred Nobel developed the use of nitroglycerin as a blasting explosive by mixing nitroglycerin with inert absorbents, particularly ” Kieselguhr “, or diatomaceous earth. He named this explosive dynamite and patented it in 1867.
What did Nobel do with nitroglycerine and kieselguhr?
He made one of his most important discoveries when he found that by mixing nitroglycerine, an oily fluid, with kieselguhr, the mixture could be turned into a paste. This material could be kneaded and shaped into rods suitable for insertion into drilling holes.
What did Alfred Nobel use for his first invention?
His first major invention was a blasting cap (igniter), a wooden plug filled with black gunpowder, which could be detonated by lighting a fuse. This in turn, caused an explosion of the surrounding nitroglycerine. Alfred Nobel worked hard to improve nitroglycerine as an explosive that could be used in blasting rock and in mining.
When did Alfred Nobel invent the first dynamite?
This early period of experimentation cost Nobel his factory, which blew up, and the deaths of a number of workmen as well as his brother, Emil. In 1867, Nobel’s discovery that nitroglycerin mixed with an absorbent substance was much safer to handle led to the invention of dynamite.
