INORGANIC HALOGEN OXIDIZERS
Abstract
Oxychlorine trifluoride has been synthesized from Cl2O + F2 in the presence of CsF, RbF, KF, and NaF as well as in their absence. Oxychlorine trifluoride has also been synthesized from uncomplexed chlorine nitrate in 84% yield. Fluorination in situ of the Cl2 + HgO reaction products has also produced ClF3O. Florox was stable in excess hydrogen fluoride or excess oxygen at ambient temperature and stable to 5-day storage at 71 C in Monel. In a flow system, thermal decomposition of Florox started near 300 C and was complete below 586 C. The predominant product recovered above 300 C was chlorine monofluoride. The complex between Florox and CsF dissociated below 150 C and allowed complete removal of contaminant ClF3 as the remaining nonvolatile solid CsClF4. Investigation of the FNO complex of ClF3O by F(19) n.m.r. showed exchange at -77 C; an infrared study at -196 C indicated the complex to be predominately covalent. Attempts to reduce ClF3O to FClO have been unsuccessfully attempted with AgF, Cl2, and Cl2O. Fluorination of Cl2O by F2, ClF3, and ClF5 has also failed to produce FClO. As a new route to oxychlorine fluorides, the reported intermediate ClO. x AsF5 has been investigated. The synthesis of new bromine oxyfluorides from Br2O complexes failed, giving mainly BrF5.
