Californium oxychloride (Cf OCl) is a radioactive actinide salt first discovered in measurable quantities in 1960. It is composed of a single californium cation and oxychloride consisting of one chloride and one oxide anion. It was the first californium compound ever isolated.[2]
Synthesis
Californium (III) oxychloride is made with the treatment of Cf2O3 with moist hydrogen chloride or CfCl3 with water vapor.[3]. The equation of the reaction with moist HCl (Hydrogen chloride) is: The Reaction with moist hydrogen chloride is called Hydrochlorination. The equation to the reaction with Water vapour and Californium trichloride: .[4]
