It is a three-membered heterocyclic compound containing one oxygen atom in the ring, and is a type of epoxide. It is a type of cyclic ether, but the three-membered ring has a large strain, so it is prone to ring-opening reactions. It is also called ethylene oxide or oxirane. It is produced by reacting ethylene chlorohydrin with an alkali hydroxide. This reaction was first performed by C. A. Wurtz of France in 1859, and is known as the laboratory method for producing ethylene oxide.

環内に酸素原子一つを含む3員環複素環式化合物で、エポキシドの一種である。環状エーテルの一種であるが、3員環が大きなひずみをもっているので開環反応をおこしやすい。酸化エチレン、オキシランともよばれる。 エチレンクロロヒドリンと水酸化アルカリとの反応により生成する。この反応は、1859年にフランスのC・A・ウュルツにより最初に行われた反応で、エチレンオキシドの実験室的製法として知られている。
