二氟化氧

Oxygen Difluoride


产品介绍 Product introduction

        二氟化氧（OF2），分子量为54.0，沸点为-144.8℃，是一种无色气体，冷冻后成为淡黄色液体。由于氟的电负性大于氧，电子向氟原子偏移，故其中氧为正二价，氟为负一价。纯二氟化氧在玻璃容器中稳定，是最稳定的氟氧化合物，200℃以上分解成氧气和氟气，可用作极强的氧化剂和氟化剂，也用于制取氧正离子盐。
Oxygen difluoride (OF2) is a colorless gas with the molecular weight of 54.0 and boiling point of 144.8℃, it is pale yellow liquid when it is freezed. Since fluorine is more electronegative than oxygen and the electron migrates toward fluorine atoms, oxygen has a charge of plus two and fluorine has a charge of minus one. Pure oxygen difluoridei s stable in glass container, it is one of the most stable fluorine oxygen compounds, it decomposes into oxygen and fluorine above 200 ℃, it can be used as a strong oxidant and fluridizer and also used for oxygen cation salts.
