Synthesis
All syntheses start from the perxenates, which are accessible from the xenates through two methods. One is the disproportionation of xenates to perxenates and xenon:
- 2 HXeO4– + 2 OH– → XeO64– + Xe + O2 + 2 H2O
The other is oxidation of the xenates with ozone in basic solution:
- HXeO4– + O3 + 3 OH– → XeO64– + O2 + 2 H2O
Barium perxenate is reacted with sulfuric acid and the unstable perxenic acid is dehydrated to give xenon tetroxide:
- Ba2XeO6 + 2 H2SO4 → 2 BaSO4 + H4XeO6
- H4XeO6 → 2 H2O + XeO4
Any excess perxenic acid slowly undergoes a disproportionation reaction to xenic acid and oxygen:
- 2 H4XeO6 → O2 + 2 H2XeO4 + 2 H2O

Famous quotes containing the word synthesis:
“The invention of photography provided a radically new picture-making process—a process based not on synthesis but on selection. The difference was a basic one. Paintings were made—constructed from a storehouse of traditional schemes and skills and attitudes—but photographs, as the man on the street put, were taken.”
—Jean Szarkowski (b. 1925)
“If in the opinion of the Tsars authors were to be the servants of the state, in the opinion of the radical critics writers were to be the servants of the masses. The two lines of thought were bound to meet and join forces when at last, in our times, a new kind of regime the synthesis of a Hegelian triad, combined the idea of the masses with the idea of the state.”
—Vladimir Nabokov (1899–1977)
“The spider-mind acquires a faculty of memory, and, with it, a singular skill of analysis and synthesis, taking apart and putting together in different relations the meshes of its trap. Man had in the beginning no power of analysis or synthesis approaching that of the spider, or even of the honey-bee; but he had acute sensibility to the higher forces.”
—Henry Brooks Adams (1838–1918)
