용도
용도
Commercial applications of oxygen difluoride are limited. It is used in organic synthesis to prepare fluoropropylenes and acylfluorides. It is used as an oxidizing and fluorinating agent in many preparative reactions and as a monomer in diolefin copolymerization.
일반 설명
A colorless poisonous gas with a strong peculiar odor. Highly toxic by inhalation. Corrosive to skin and eyes. Can explode on contact with water. Decomposes to toxic gaseous fluorine if heated to high temperature. Prolonged exposure of the containers to high heat may result in their violent rupturing and rocketing. Used as an oxidizer for propellants.
제조 및 합성 방법
제조 방법
Oxygen difluoride may be prepared by passing fluorine gas slowly through a dilute solution of caustic soda. Usually a 2% solution of NaOH is suitable for the preparation: 2F2 + 2 Na OH → 2NaF + OF2 + H2O At a higher alkali concentration, oxygen is formed: 2F2 + 4NaOH → 4NaF + 2H2O + O2 Oxygen difluoride can be produced by electrolysis of an aqueous solution of HF or, alternatively, electroylzing molten potassium hydrogen difluoride, KHF2, in the presence of water.
