Trioxygen difluoride is an inorganic chemical compound of oxygen from the group of oxygen fluorides . In more recent literature, the existence of the connection is not considered certain. It is assumed that it is a mixture of dioxygen difluoride and tetra oxygen difluoride .

Extraction and presentation

Trioxygen difluoride can be obtained by reacting oxygen with fluorine at around −190 ° C in an electrical discharge at low pressure.

${\displaystyle \mathrm {3\ O_{2}+2\ F_{2}\longrightarrow 2\ O_{3}F_{2}} }$

It was first synthesized and studied in the late 1930s by the Japanese scientists Aoyama and Sakuraba.

properties

Trioxygen difluoride is a deep red liquid that solidifies at −190 ° C and tends to undercool. It decomposes above −157 ° C into oxygen and dioxygen difluoride . It is a strong oxidizing agent, comparable to, for example, dioxygen difluoride and more reactive than fluorine and oxygen difluoride .
