Fluorine reaction with air solid
WebFluorine reacts violently with organic matter (such as rubber, wood, and cloth), and controlled fluorination of organic compounds by the action of elemental fluorine is only possible if special precautions are taken. WebWhen fluorine gas is distilled through cold water (at low temperature), oxygen difluoride (F 2 O) is given as the product. But due to less solubility, this method is not efficient. …
