15.7: Synthesis of Epoxides - Chemistry LibreTexts
Epoxides (also known as oxiranes) are three-membered ring structures in which one of the vertices is an oxygen and the other two are carbons. The most important and simplest epoxide is ethylene oxide which is prepared on an industrial scale by catalytic oxidation of ethylene by air.
Epoxide | Synthesis, Reactions, Ring-Opening | Britannica
epoxide, cyclic ether with a three-membered ring. The basic structure of an epoxide contains an oxygen atom attached to two adjacent carbon atoms of a hydrocarbon. The strain of the three-membered ring makes an epoxide much more reactive than a typical acyclic ether.
Epoxide - Wikipedia
Simple epoxides are often referred to as oxides. Thus, the epoxide of ethylene (C 2 H 4) is ethylene oxide (C 2 H 4 O). Many compounds have trivial names; for instance, ethylene oxide is called "oxirane".
Epoxide Functional Group - ChemTalk
Thus, the simplest epoxide, C 2 H 4 O, has the IUPAC name of 1,2-epoxyethane. Other examples include 3,4-epoxyheptane, with an epoxy group between carbons 4 and 5, and 1,2-epoxy-3,5-cyclohexadiene. Another common epoxide naming convention involves simply naming the parent alkene followed by the term oxide.

The most important and simplest epoxide is ethylene oxide which is prepared on an industrial scale by catalytic oxidation of ethylene by air. Ethylene oxide is used as an important chemical feedstock in the manufacturing of ethylene glycol, which is …
18.4 Cyclic Ethers: Epoxides - Organic Chemistry | OpenStax
Ethylene oxide, the simplest epoxide, is an intermediate in the manufacture of both ethylene glycol, used for automobile antifreeze, and polyester polymers. Approximately 37 million tons of ethylene oxide is produced worldwide each year, most of it by air oxidation of ethylene over a silver oxide catalyst at 300 °C.
3.9: Ethers, Epoxides and Sulfides - Chemistry LibreTexts
Epoxides. An epoxide is a cyclic ether with three ring atoms. These rings approximately define an equilateral triangle, which makes it highly strained. The strained ring makes epoxides more reactive than other ethers. Simple epoxides are named from the parent compound ethylene oxide or oxirane, such as in chloromethyloxirane.
Synthesis of Epoxides - Organic Chemistry Tutor
We’ll explore the two primary methods for creating epoxides: the epoxidation of alkenes with peroxy acids, and the process of forming epoxides from halohydrins through intramolecular S N 2 reactions.
Epoxide - an overview | ScienceDirect Topics
Epoxides are organic three-membered cyclic oxygen compounds that derive from oxidative metabolism of endogenous metabolites (e.g., intermediate in cholesterol biosynthesis), as well as xenobiotic compounds (e.g., metabolite of benzpyrene), via chemical and …
Epoxides - Faculty of Science
Epoxides are cyclic ethers, a 3 membered ring (see above diagram). Their reactivity is such that they are essentially a separate functional group. There are two methods for naming epoxides: as the oxide of the corresponding alkene (this relates to a method of synthesising them).
