Nitroglycerin (NG) (alternative spelling nitroglycerine), also known as trinitroglycerol (TNG), nitro, glyceryl trinitrate (GTN), or 1,2,3-trinitroxypropane, is a dense, colorless or pale yellow, oily, explosive liquid most commonly produced by nitrating glycerol with white fuming nitric acid under conditions appropriate to the formation of the nitric acid ester.
Nitroglycerin, also known as glyceryl trinitrate (GTN), is a vasodilator used for heart failure, high blood pressure (hypertension), anal fissures, painful periods, and to treat and prevent chest pain caused by decreased blood flow to the heart or due to the recreational use of cocaine.
Toxic by inhalation liquid, n.o.s. with an inhalation toxicity lower than or equal to 1000ml/m 3 and saturated vapour concentration greater than or equal to 10 LC 50: UN 3383: 6.1: Toxic by inhalation liquid, flammable, n.o.s. with an inhalation toxicity lower than or equal to 200ml/m 3 and saturated vapour concentration greater than or equal ...
The technique involves displacing and detonating nitroglycerin in hydraulically induced fractures followed by wellbore shots using pelletized TNT. [14] TNT is valued partly because of its insensitivity to shock and friction, with reduced risk of accidental detonation compared to more sensitive explosives such as nitroglycerin. TNT melts at 80 ...
Because of the risks of this medication, people taking alpha-blockers, over-the-counter nitrate supplements (like amyl nitrate, isosorbide mononitrate, isosorbide dinitrate, or nitroglycerin) or ...
Tovex Firebreak II used on Upper Bear Creek Trail in the Angeles National Forest. Tovex (also known as Trenchrite, Seismogel, and Seismopac) is a water-gel explosive composed of ammonium nitrate and methylammonium nitrate that has several advantages over traditional dynamite, including lower toxicity and safer manufacture, transport, and storage.
If ingested, like nitroglycerine, it rapidly causes vasodilation through the release of nitric oxide, a physiological signaling molecule that relaxes smooth muscle. [clarification needed] Consequently, diethylene glycol dinitrate has occasionally been used medically to relieve angina, which is substernal chest pain associated with impaired cardiac circulation.
Toxic substances – Substances with an LD 50 value ≤ 300 mg/kg (oral) or ≤ 1000 mg/kg (dermal) or an LC 50 value ≤ 4000 ml/m 3 (inhalation of dusts or mists) e.g. nearly everything that contains cyanide groups
