Acetylene (systematic name: ethyne) is the chemical compound with the formula C 2 H 2 and structure H−C≡C−H.It is a hydrocarbon and the simplest alkyne. [8] This colorless gas is widely used as a fuel and a chemical building block.
Thermobaric and fuel–air explosives have been used in guerrilla warfare since the 1983 Beirut barracks bombing in Lebanon, which used a gas-enhanced explosive mechanism that was probably propane, butane, or acetylene. [109] The explosive used by the bombers in the US 1993 World Trade Center bombing incorporated the FAE principle by using ...
Dalén himself was blinded in an acetylene explosion. In 1896, French chemists Georges Claude and Albert Hess discovered that large quantities of acetylene could be dissolved in acetone and rendered nonexplosive. [1] As the liquid was reduced by consumption or cooling, explosive acetylene gas would collect in the space above the liquid's surface.
Only pure chemicals belong here not fuel air mixtures to be here a gas must have an upper explosive limit of 100%. Pages in category "Explosive gases" The following 9 pages are in this category, out of 9 total.
Controlling gas and vapor concentrations outside the flammable limits is a major consideration in occupational safety and health. Methods used to control the concentration of a potentially explosive gas or vapor include use of sweep gas, an unreactive gas such as nitrogen or argon to dilute
Silver acetylide can be produced by passing acetylene gas through a solution of silver nitrate: [3] 2 AgNO 3 (aq) + C 2 H 2 (g) → Ag 2 C 2 (s) + 2 HNO 3 (aq) The reaction product is a greyish to white precipitate. This is the same synthesis from Berthelot in which he first found silver acetylide in 1866. [4]
The velocity of detonation is an important indicator for overall energy and power of detonation, and in particular for the brisance or shattering effect of an explosive which is due to the detonation pressure. The pressure can be calculated using Chapman-Jouguet theory from the velocity and density.
Very often, a flammable substance is led to the machine. Common substances are air with propane gas or acetylene. A device is then used to detonate the mixture remotely. These devices are often self-built, improvised explosive devices. In other cases, true explosives or pyrotechnics are used. Such attacks began in the Netherlands.
