Abstract
Uranyl p-toluenesulfonate was synthesized and studied. This salt crystallizes from aqueous solution as pentahydrate. Its solubility is 2.57 mol kg- 1 at 25°C. Anhydrous salt and lower hydrates were prepared. Hydration of the anhydrous salt in air at various water vapor pressures was studied. The TGA data show that uranyl p-toluenesulfonate pentahydrate has the layered structure of the hydration shell. The IR spectra of crystal hydrates with the same composition obtained by the dehydration-hydration procedure are the same in the region of frequencies of sulfonate group and differ in the region of water vibrations.
