A. Mutalib et al., BASE HYDROLYSIS OF TRIS(ACETYLACETONATO)METAL(III) COMPLEXES INVOLVING TECHNETIUM AND RUTHENIUM, Journal of radioanalytical and nuclear chemistry, 170(1), 1993, pp. 67-77
Base hydrolysis of Tc(acac)3 and Ru(acac)3 was studied in 0.1-1M NaOH
at different temperatures. In spite of apparent similarity of these co
mplexes Tc(acac)3 showed more complexity than Ru(acac)3 in kinetic beh
avior. Tc(acac)3 decomposes with a rate, d[Tc(acac)3]/dt = (k1[OH-] + k2[OH-]2)[Tc(acac)3], where k1 and k2 at 25-degrees-C are (1.67 +/-
0.11) x 10(-5) mol-1 . s-1 and (1.71 +/- +/- 0.14) x 10(-5) mol-1 . s-
1, respectively. Decomposition of Ru(acac)3 is expressed by the rate e
quation d[Ru(acac)3]/dt = k[OH-][Ru(acac)3], where k at 37-degrees-C i
s (8.01 +/- 0.23) x 10(-6) mol-2 . s-1.
