Abstract

Homogeneous solutions for DNA hydrolysis are prepared from cerium(IV) ion, lanthanide(III) ion, and dextran. When [Ce(IV)] = 10, [Pr(III)] = 5, and [dextran (monomeric residue)] = 20 mmol dm−3 at pH 7.0 and 50 °C, the pseudo-first-order rate constant for the hydrolysis of thymidylyl(3′→5′)thymidine (TpT) is 0.10 h−1.

Abstract

We have studied on the mechanism of the photocatalytic dehydrogenation of methanol over Pt/TiO2. D2 was only evolved from CH3OD, and D2, HD, and H2 were detected in the evolved gas in the case of the mixed sample of CH3OD and CH3OH. These results show that the evolved hydrogen came from hydroxyl hydrogen atom of methanol. And the rate determining step was discussed in connection with comparison among the evolution rates of H2, HD, and D2, respectively.
