Phosphate Diester Hydrolysis by Dinuclear Tb(III) Complexes with BDBPH in Second-order Dependence
摘要:
The kinetic study on the hydrolysis reaction of bis(4-nitrophenyl) phosphate (BNPP) catalyzed by Tb-BDBPH system(2:1) was carried out in 50% ethanol solution (pH 7.0-10.0) at 35℃ with I=0.10NaNO3. The second-order rate constant kBNPP, 2.3×10-3 (mol-1L S-1), was determined. The dinuclear monohydroxo species, L-2Tb-OH, is kinetically mainly active species.The hydrolysis rate of BNPP by the complex is increased almost 2.6 million-fold compared with the background hydroxide rate at the same condition.
