A generic epoxide. In organic chemistry, an epoxide is a cyclic ether, where the ether forms a three-atom ring: two atoms of carbon and one atom of oxygen. This triangular structure has substantial ring strain, making epoxides highly reactive, more so than other ethers. They are produced on a large scale for many applications.
Ethylene oxide is an organic compound with the formula C2H4O. It is a cyclic ether and the simplest epoxide: a three-membered ring consisting of one oxygen atom and two carbon atoms. Ethylene oxide is a colorless and flammable gas with a faintly sweet odor.
Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. [1] The IUPAC name for an epoxide group is an oxirane.
Epoxy value. Epoxy value derives from the Epoxy equivalent weight (EEW) or Weight Per Epoxide (WPE) and is a measure of the epoxy content of an epoxy resin or epoxy reactive diluent, or glycidyl ether. [1] This is an important parameter as it allows determination of the correct mix ratio of an epoxy system with a curing agent. [2]
A cyclic ether. Also the simplest epoxide. Dimethyl ether: A colourless gas that is used as an aerosol spray propellant. A potential renewable alternative fuel for diesel engines with a cetane rating as high as 56–57. Diethyl ether: A colourless liquid with sweet odour. A common low boiling solvent (b.p. 34.6 °C) and an early anaesthetic ...
Chemical reaction between ethylene oxide and substrate. In organic chemistry, ethoxylation is a chemical reaction in which ethylene oxide (C2H4O) adds to a substrate. It is the most widely practiced alkoxylation, which involves the addition of epoxides to substrates. In the usual application, alcohols and phenols are converted into R (OC2H4)nOH ...
Silyl enol ether. In organosilicon chemistry, silyl enol ethers are a class of organic compounds that share the common functional group R3Si−O−CR=CR2, composed of an enolate (R3C−O−R) bonded to a silane (SiR4) through its oxygen end and an ethene group (R2C=CR2) as its carbon end. They are important intermediates in organic synthesis ...
Glycidyl methacrylate (GMA) is an ester of methacrylic acid and glycidol. Containing both an epoxide and an acrylate groups, the molecule is bifunctional. It is a common monomer used in the production of epoxy resins. While typical home epoxies contain diglycidyl ether of bisphenol A (DGEBA), glycidyl methacrylate is instead used to provide ...
