Epoxides common names

Epichlorohydnn is the common name of an industrial chemical used as a component in epoxy cement The molecular formula of epichlorohydnn is C3H5CIO Epichlorohydnn has an epoxide functional group it does not have a methyl group Write a structural formula for epichloro hydrin... 

Three membered rings that contain oxygen are called epoxides At one time epox ides were named as oxides of alkenes Ethylene oxide and propylene oxide for exam pie are the common names of two industrially important epoxides... 

Homopolymers of PO and other epoxides are named a number of ways after the monomer, eg, poly(propylene oxide) (PPO) or polymethjioxirane from a stmctural point of view, polyoxypropylene or poly(propylene glycol) or from the Chemicaly hstracts (CA) name, poly[oxy(methyl-l,2-ethanediyl)], a-hydro- CO-hydroxy-. Common names are used extensively in the Hterature and in this article. 

Epoxides (Oxiranes) We have already encountered some of the chemistry of epoxides in Section 8-12. Epoxides are three-membered cyclic ethers, usually formed by peroxyacid oxidation of the corresponding alkenes. The common name of an epoxide is formed by adding oxide to the name of the alkene that is oxidized. The following reactions show the synthesis and common names of two simple epoxides. 

Epoxides are also named as alkene oxides, since they are often prepared by adding an O atom to an alkene (Chapter 12). To name an epoxide this way, mentally replace the epoxide oxygen by a double bond, name the alkene (Section 10.3), and then add the word oxide. For example, the common name for oxirane is ethylene oxide, since it is an epoxide derived from the alkene ethylene. We will use this common method of naming epoxides after the details of alkene nomenclature are presented in Chapter 10. 

The fourth class which are peculiar to PVC have one thing in common namely an ability to react witti HCl. They include such diverse substances as inorganic lead salts, heavy metal soaps, organo-tin compounds, epoxides and many others. Although their ability to react with HCl may be a contributory factor their main function is undoubtedly to react with and deactivate potential sites of initiation such as branch points or areas of unsaturation.. ... 

Ethers in which the oxygen atom is incorporated into a three-membered ring are called epoxides or oxiranes. The common name of an epoxide uses the common name of the alkene, followed by oxide, assuming that the oxygen atom is where the tt bond of an alkene would be. The simplest epoxide is ethylene oxide. 

Epoxides are cyclic ethers with three-membered rings. In lUPAC nomenclature epoxides are called oxiranes. The simplest epoxide has the common name ethylene oxide ... 

Common names for epoxides are derived by giving the common name of the alkene from which the epoxide might have been derived, followed by the word oxdde, an example is ethylene oxide. 

In common nomenclature, epoxides are named from the alkene from which they are derived followed by the word oxide. 

For our current discussion, we will focus on oxiranes, cychc ethers containing a three-membered ring system. This ring system is more reactive than other ethers because it has significant ring strain. Substituted oxiranes, which are also called epoxides, can have up to four R groups. The simplest epoxide (no R groups) is often called by its common name, ethylene oxide. 

Substitutive lUPAC nomenclature treats epoxides as epoxy derivatives of alkane parents the epoxy-piefix is hsted in alphabetical order like other substituents. Some industrial chemicals have common names formed by adding the word oxide to the name of the alkene. 

Preparations of these 1,2-bis-electrophiles share some common features. In particular, esters of trifluoropyruvic acid (like MeTFP 1015) are available commercially, but they can be prepared in two steps from an epoxide 1067 (namely, hexafluoropropylene oxide, which is available on industrial scale) [633] (Scheme 228). hi turn, epoxides 1067 are obtained by oxidation of the corresponding perfluorinated alkenes, e.g. with hypochlorite [634]. 

Three- through six-membered cyclic ethers have common names. Cyclic ethers with three ring atoms are called epoxides. Since these compounds can be made by oxidizing an alkene, the common name of an epoxide adds oxide to the name of the alkene.
