研究了铀(V)歧化反应的动力学和机理。与之前的一项研究一致（T. W.牛顿和F. B.贝克）。化学。， 4,1166(1965))，歧化速率被观察到由于U （VI）的存在而减慢，这种影响归因于形成了一个Uv 'UVI配合物，其吸收光谱在360- 760nm范围内被测量。考察了离子强度、酸浓度和络合阴离子的存在对歧化率的影响。在D20溶液中进行了反应研究，并对反应机理进行了探讨。
The kinetics and mechanism of the disproportionation ofU (V) have been investigated. In agreement with a previous study (T. W. Newton and F. B. Baker, Inorg. Chem., 4, 1166 (1965)), the rate of disproportionation was observed to be retarded by the presence of U (VI), the effect being attributed to the formation of a Uv’UVI complex whose absorption spectrum in the range 360-760 nm has been measured. The effect of ionic strength, acid concentration, and the presence of com-plexing anions on the disproportionation rate has been examined. The reaction has alsobeen studied in D20 solution and reaction mechanisms are discussed.
