ABSTRACT:
The peroxonium salts, H.sub.3 O.sub.2.sup.+ Sb.sub.2 F.sub.11.sup.-, H.sub.3 O.sub.2.sup.+ SbF.sub.6.sup.- and H.sub.3 O.sub.2.sup.+ AsF.sub.6.sup.-, are prepared by protonation of H.sub.2 O.sub.2 in anhydrous HF solutions of the corresponding Lewis acids. The salts decompose producing the corresponding H.sub.3 O.sup.+ salts and O.sub.2 in the temperature range of from 20.degree. to 50.degree. C. and thus are useful as oxidizers in situations where the production of oxygen in the 20.degree.-50.degree. C. temperature range is desirable. The salts also provide a convenient means for storing H.sub.2 O.sub.2 in a solid form.
