摘要

The reactions of rhodium oxide (Rh_2O_3) and / or rhodium metal with aluminum chloride (P_(AlCl_3 <= 3atm) under a chlorine atmosphere (Pcl_2 <=1 atm) have been studied. The formation of a Rh-Al-Cl gas complex is shown to enable the vapor transport of RhCl_3. UV/VIS spectrophotometry is used for characterizing the rhodium gas complex. A procedure for recovering rhodium metal from spent catalysts is suggested based on the vapor complexation of rhodium chloride with aluminum chloride.
