摘要

UF(6)is commonly employed in enrichment technologies and is known to react rapidly with water vapor to form radioactive particulates and hydrofluoric acid vapor. The kinetics of the UF(6)hydrolysis reaction have been observed directly for the first time. The rate appears to be half order and second order for UF(6)and water, respectively, with a rate constant of 1.19 +/- 0.22 Torr(-3/2)s(-1). The proposed mechanism involves formation of the [UF6 center dot 2H(2)O] adductviatwo separate reactions.
