Diethyl ether hydroperoxide forms polymers known as diethyl ether peroxide, or ethylidene peroxide: The peroxide is a colorless oil that is an extremely brisant and friction sensitive explosive material , however the polymeric materials are solid making them more dangerous as evaporation of the volatile diethyl ether can leave thin films of ...
Auto-oxidation reaction is also observed with common ethers, such as diethyl ether, diisopropyl ether, tetrahydrofuran, and 1,4-dioxane. An illustrative product is diethyl ether peroxide . Such compounds can result in a serious explosion when distilled. [ 12 ]
Reactions where the stereochemistry of the hydroxyl group is inverted saw lower regioselectivity, and removal of the hydroxyl group gave the exclusive formation of the other regioisomer. It is likely that the close proximity of the hydroxyl group in the syn isomer acidifies the ring-fusion proton through hydrogen-bonding interactions, thus ...
The reaction is catalyzed by acids, usually sulfuric acid. The method is effective for generating symmetrical ethers, but not unsymmetrical ethers, since either OH can be protonated, which would give a mixture of products. Diethyl ether is produced from ethanol by this method. Cyclic ethers are readily generated by this approach.
For industrial reactions a radical initiator, such as benzoyl peroxide, will be intentionally added. All of these processes lead to the generation of carbon centred radicals on the polymer chain (R•), typically by abstraction of H from labile C-H bonds.
Diacyl peroxides are typically prepared by treating hydrogen peroxide with acid chlorides or acid anhydrides in the presence of base: [1] H 2 O 2 + 2 RCOCl → (RCO 2) 2 + 2 HCl H 2 O 2 + (RCO) 2 O → (RCO 2) 2 + H 2 O. The reaction competes with hydrolysis of the acylating agent but the hydroperoxide anion is a superior nucleophile relative ...
After removing the ether peroxide from the building, crews took the chemical to a nearby rock quarry and detonated it safely, according to Johnson. The buildings evacuated on campus were reopened ...
The Baeyer–Villiger oxidation is an organic reaction that forms an ester from a ketone or a lactone from a cyclic ketone, using peroxyacids or peroxides as the oxidant. [1] The reaction is named after Adolf von Baeyer and Victor Villiger who first reported the reaction in 1899.
