Dihydrogen monoxide parody Dihydrogen monoxide parody The dihydrogen monoxide parody involves calling water by the unfamiliar chemical name "dihydrogen monoxide" (DHMO), or "hydroxylic acid" in some cases, and listing some of water's well-known effects in a particularly alarming manner, such as accelerating corrosion and causing suffocation. The parody often calls for dihydrogen monoxide to be banned, regulated, and labeled as dangerous. It illustrates how a lack of scientific literacy and an exaggerated analysis can lead to misplaced fears. The parody gained renewed popularity in the late 1990s when a 14-year-old student, Nathan Zohner, collected anti-DHMO petitions for a science project about gullibility. The
Ethylene oxide oxide with compounds containing active methylene group leads to the formation of butyrolactones: Ethylene oxide enters into the Friedel–Crafts reaction with benzene to form phenethyl alcohol: Styrene can be obtained in one stage if this reaction is conducted at elevated temperatures () and pressures (), in presence of an aluminosilicate catalyst. A series of polynomial heterocyclic compounds, known as crown ethers, can be synthesized with ethylene oxide. One method is the cationic cyclopolymerization of ethylene oxide, limiting the size of the formed cycle: To suppress the formation of other linear polymers the reaction is carried out in a highly dilute
