The VOC Solvents Emissions Directive was the main policy instrument for the reduction of industrial emissions of volatile organic compounds (VOCs) in the European Union. It covers a wide range of solvent-using activities, e.g. printing, surface cleaning, vehicle coating, dry cleaning and manufacture of footwear and pharmaceutical products.
The Protocol to the 1979 Convention on Long-Range Transboundary Air Pollution Concerning the Control of Emissions of Volatile Organic Compounds or Their Transboundary Fluxes (known as the Volatile Organic Compounds Protocol or the VOC Protocol) is a protocol to the Convention on Long-Range Transboundary Air Pollution which aims to provide for the control and reduction of emissions of volatile ...
Lower flammability limits for many organic materials are in the range of 10–50 g/m 3, which is much higher than the limits set for health reasons, as is the case for the LEL of many gases and vapours. Dust clouds of this concentration are hard to see through for more than a short distance, and normally only exist inside process equipment.
The ether normally has a water content of 1.5–2%; in absence of water, ethylene oxide polymerizes. [37] Halohydrins can also be obtained by passing ethylene oxide through aqueous solutions of metal halides: [33] 2 (CH 2 CH 2)O + CuCl 2 + 2 H 2 O → 2 HO–CH 2 CH 2 –Cl + Cu(OH) 2 ↓
Toluene is an organic compound which is mostly harmless to adults and is sometimes abused as an inhalant. Fetal toluene syndrome has been defined and resembles fetal alcohol syndrome with resultant birth defects, but the U.S. Centers for Disease Control and Prevention have identified differentiating features between the two syndromes including FTS having the additional facial features of ...
It forms adducts with a variety of Lewis acids. It is classified as a hard base and its base parameters in the ECW model are E B = 1.86 and C B = 1.29. Dioxane produces insoluble coordination polymers by linking metal centers. [17] In this way, it is used to drive the Schlenk equilibrium, allowing the synthesis of dialkyl magnesium compounds. [10]
Acetone (2-propanone or dimethyl ketone) is an organic compound with the formula (CH 3) 2 CO. [22] It is the simplest and smallest ketone (>C=O).It is a colorless, highly volatile, and flammable liquid with a characteristic pungent odour, very reminiscent of the smell of pear drops.
BPA has been found to interact with a diverse range of hormone receptors, in both humans and animals. [78] It binds to both of the nuclear estrogen receptors (ERs), ERα and ERβ . BPA is a selective estrogen receptor modulator (SERM), or partial agonist of the ER, so it can serve as both an estrogen agonist and antagonist .
