Epoxides belong to a group of reactive organic compounds which contain an epoxide functionality, i.e. a three-membered cyclic ether containing two C atoms and one O atom. Epoxides are prepared by epoxidation or from hydroperoxides during autoxidation of olefins. Furthermore, epoxides can be synthesized by dehydrohalogenation of halohydrins or by dehydration of 1,2-diols.

Epoxides react with numerous compounds with ring opening yielding alcohols, halohydrins, glycols, amino alcohols etc. Therefore, the most important representatives for the chemical industry, ethylene glycol and propylene oxide, are starting materials for many industrial products. Reactions under suitable conditions with compounds containing active hydrogen atoms can lead to polymerization. For example, epoxide waxes and products of ethoxylation, such as polyethylene glycoles, -oxide and polyethers in general, are prepared this way.
