In the presence of caesium carbonate 1, the direct reaction of CO2(110 atm) with CO (20 atm) results in reductive capture of CO2 to give caesium oxalate 2 in good yield at elevated temperature (380 °C).
High-pressure responses of RbHCO3 and CsHCO3 were characterized by in situ Raman spectroscopy and X-ray and neutron diffraction observations. RbHCO3 exhibited a monoclinic (phase IV) and a triclinic (phase V) high-pressurephase at ∼0.5 GPa and room temperature. Increasing compression induced unique behavior in a specific cell parameter (a in phase IV or c in phase V), which first increased, and then

Methods to recover or separate cesium formate or rubidium formate or both from a mixed alkali metal formate blend are described. One method involves adding cesium sulfate or rubidium sulfate to the mixed alkali metal formate blend in order to preferentially precipitate potassium sulfate from the mixed alkali metal formate blend. Another method involves adding cesium carbonate or cesium bicarbonate or both to preferentially precipitate potassium carbonate/bicarbonate and/or other non-cesium or non-rubidium metals from the mixed alkali metal blend. Further optional steps are also described. Still one other method involves converting cesium sulfate to cesium hydroxide.

The crystal and molecular structures of acid salt Rb2H3IO6 were determined. The anion part of the structure is united via a hydrogen bonding system to form a layer parallel to the xy plane. The proton conductivity in the temperature range of 40-60degreesC was found to be 10(-7)-5 x 10(-6) Ohm(-1)cm(-1), E-a = 2 eV.
