Peroxide ether
WebEthers. Organic peroxides are formed in ethers via a mechanism catalyzed by heat, light and oxygen. In addition to potentially interfering with a given method due to their high reactivity, ether peroxides are highly unstable and represent a potential explosion hazard at concentrations above 100ppm. Lower levels of these peroxides may also ... WebTypical classes of compounds that form peroxides include: Ethers, acetals, and ketals, especially cyclic ethers and those with primary and/or secondary alkyl groups ; Aldehydes, …

WebThe peroxide list does not address the broad range of chemical-specific hazards and properties that are associated with the individual chemicals. For instance, 2-Butanol, Diethyl ether, and Tetrahydrofuran, among many others, form explosive levels of peroxides on concentration. Furthermore, Isopropyl ether, Tetrafluoroethylene, and Butadiene ... WebOn no account should any ether with a peroxide content above 50 ppm be used without purification, an on no account should any ether be distilled or evaporated to dryness, since when using large volumes even low peroxide concentrations, which are not readily detected by the above methods, can concentrate to dangerous levels. Removal of Peroxides 1.
WebUse and Storage of Peroxide-Forming Solvents. The solvents most commonly used in the laboratory solvents, such as diethyl ether, tetrahydrofuran, cyclohexene, glycol ethers, … WebPeroxide-forming chemicals are a class of compounds that have the ability to form shock-sensitive explosive peroxide crystals when exposed to various storage conditions or extended storage times. These peroxide crystals can violently detonate when subjected to: thermal and mechanical shock, impact and friction, or combined with other compounds.
WebPeroxide-forming chemicals should be stored in their original manufacturer’s container whenever possible. This is very important in the case of diethyl ether because the iron in the steel containers that the material is shipped in acts as a peroxide inhibitor. Inhibitors Webperoxide formation. Time Autoxidation generally refers to the slow reaction between organic chemicals and elemental oxygen under mild conditions. Over time, and in the presence of …
WebPeroxides are a class of chemical compounds with unusual stability problems and are one of the most hazardous classes of chemicals routinely handled in the laboratory. Peroxides can be formed via intentional chemical reactions (i.e., ozonolysis), but just as hazardous is the inadvertent peroxide formation during storage of certain compounds.
