The epoxide resins also known as epoxy resins and, occasionally, as ethoxyline resins, are characterized by the possession of more than one 1,2-epoxy group per molecule. This group may lie within the body of the molecule but is usually terminal. The three-membered epoxy ring is highly strained and is reactive to many substances, particularly with ...

Aliphatic Epoxide Carboxylation
Annual Review of Biochemistry, 2003▪ Abstract Aliphatic epoxides (epoxyalkanes) are highly reactive electrophilic molecules that are formed from the monooxygenase-catalyzed epoxidation of aliphatic alkenes. The bacterial metabolism of short-chain epoxyalkanes occurs by a three-step pathway resulting in net carboxylation to β-ketoacids.

An epoxidation byCorynebacterium simplex
Experientia, 1964Wahrend unserer Untersuchungen uber die mikrobiologische Dehydrierung verschiedener 16β-Methylsteroide durch Bakterienkulturen vonCorynebacterium simplex, wurde eine neue Art von Umwandlung beobachtet. Von 16β-Methyl-Δ9(11)-pregnen-17α, 21-diol-3, 20-dion-21-acetat ausgehend, gelang es aus den Kulturfiltraten 16β-Methyl-Δ1, 4-pregnadien-9α, 11α-epoxy ...

Fluoroalkylethylenes and their epoxides
Journal of Fluorine Chemistry, 1991Abstract Fluoroalkylethylenes of types 1 and 2 are unresponsive to the usual reagents for epoxidation, but recent methods have made the epoxides and related halohydrins readily available. Use of the reagent X2/nSO3, which readily attacks the double bond of both 1 and 2, will be described in detail and compared to two other effective reagents ...

Ethyl ether dates as far back as the thirteenth century when it was first discovered by mixing ethanol and sulfuric acid, historically known as oil of vitriol. During the 1800s, it was first used widely as an anesthetic until the mid-1950s when it was eventually replaced by less flammable anesthetics.

Simultaneous steady-state plasma concentrations of carbamazepine and carbamazepine-10,11-epoxide have been measured by high pressure liquid chromatography in 101 epileptic children and adults taking the drug. There was either no statistically significant correlation, or only a very poor correlation, between drug dose and steady-state plasma levels of a)
