The other product, oxygen difluoride, is almost as strong an oxidizer as dioxygen difluoride, which is only stronger because it's oxygen difluoride plus more oxygen. Ice? No votes so far! Dioxygen difluoride is so volatile that it makes almost any organic substance ignite and explode at any temperature hotter than 300°F below zero. The general method of preparation of many oxygen fluorides is a gas-phase electric discharge in cold containers including O 2 F 2. “Being a high energy oxidizer, dioxygen difluoride reacted vigorously with organic compounds, even at … When did Elizabeth Berkley get a gap between her front teeth?

Some compounds are so unpleasant it would be better if they had names like ‘reconsideric acid’ or ‘notworthite’. Dioxygen difluoride is made up of two fluorine atoms and two oxygen atoms - earning it the nickname FOOF. 0000004626 00000 n Thus, the addition of even one drop of ozone difluoride to solid anhydrous ammonia will result in a mild explosion, when they are both at 90 K each. ‘No other chemical,’ he writes in 1984, using italics for emphasis, ‘is capable of PuF6 generation at temperatures even approaching the low temperatures used here.’ He even patented the method that same year, highlighting how with this superior approach there is virtually no damage to the containment vessels – no doubt a rare and impressive selling point. Dioxygen difluoride, O 2 F 2, is an unstable compound. 0 Decomposes to toxic gaseous fluorine if heated to high temperature. The latest addition to the long list of chemicals that I never hope to encounter takes us back to the wonderful world of fluorine chemistry.
