Abstract

PURPOSE: To form and recover RuO4 by a dry method in a short time and a good yield by reacting ruthenium oxide hydrate or ruthenium hydroxide with F2 gas at room temp. and by cooling the reaction product gas with a cold trap.
CONSTITUTION: A reaction tube storing RuO2.xH2O or Ru(OH)3 is evacuated, introduced into a reaction tube contg. F2 gas of 300W500 mmHg held at room temp., and allowed to stand for 20 minW1 hr, forming RuO4. The reaction product gas contg. the RuO4 and HF simultaneously formed is passed through a cold trap cooled to around -30°C to release the HF from the trap, and the RuO4 is captured with the trap. The vapor press. of HF at -30°C is about 100 mmHg, and that of RuO4 about 0.1 mmHg.
