heterocyclic compound
There are many different sulfur-containing heterocycles. One of the best known is thiophene, C4H4S, derivatives of which occur as plant pigments and as other natural products such as biotin.
Oxirane, also known as ethylene oxide, is produced on a large industrial scale through the direct oxidation of ethylene using oxygen. This process is facilitated by a silver catalyst supported on an inactive, refractory material.123
As a highly reactive heterocyclic compound containing a three-membered ring, oxirane serves as a vital bulk chemical. Its industrial importance stems from its ability to undergo ring-opening reactions, which are used to manufacture essential products such as ethylene glycol—commonly used as antifreeze—as well as various polymers and plastics.12
