Dichlorine heptaoxide Usage And Synthesis
UsesCl2O7 is a colorless liquid that is an excellent oxidizer. It is perchloric acid with the water removed.
PreparationDichlorine Heptoxide is a chemical compound with the formula Cl2O7. Dichlorine heptoxide is the anhydride of perchloric acid and is related to perchlorates in general. It is produced by the careful distillation of perchloric acid in the presence of a dehydrating agent such as phosphorus pentoxide:
2HClO4＋P4O10→Cl2O7＋H2P4O11
It is also produced by the careful distillation of perchloric acid that has been dehydrated with P2O5. It may also be formed by illumination of mixtures of chlorine and ozone. It slowly hydrolyzes back to perchloric acid, if allowed to contact moisture in any way. Dichlorine heptoxide melts at 91.5°C and boils at 82°C. It is highly explosive and can be set off with flame, mechanical shock, and on contact with organic substances. Cl2O7 is an endothermic molecule, which means that it is intrinsically unstable:
2Cl2O7→2Cl2＋7O2 (DH＝＋135 kJ/mol).
