The peroxides from methylrhenium trioxide (MTO) and hydrogen peroxide, CH 3ReO 2(η 2-O 2), A, and CH 3Re(O)(η 2-O 2) 2(H 2O), B, have been fully characterized in both organic and aqueous media by spectroscopic means (NMR and UV−vis). In aqueous solution, the equilibrium constants for their formation are K 1 = 16.1 ± 0.2 L mol - 1 and K 2 = 132 ± 2 L mol - 1 at pH 0, μ = 2.0 M, and 25 °C.

In the presence of hydrogen peroxide the catalyst decomposes to methanol and perrhenate ions with a rate that is dependent on [H 2O 2] and [H 3O +]. The complex peroxide and pH dependences could be explained by one of two possible pathways: attack of either hydroxide on A or HO 2 - on MTO. The respective second-order rate constants for these reactions which were deduced from comprehensive kinetic treatments are k A = (6.2 ± 0.3) × 10 9 and k MTO = (4.1 ± 0.2) × 10 8 L mol - 1 s - 1 at μ = 0.01 M and 25 °C. The plot of log k ψ versus pH for the decomposition reaction is linear with a unit slope in the pH range 1.77−6.50.

Polotebnov was the first to advance the theory that a skin disease should be regarded as a disease of the entire body and that the pathology of the disease should be studied within the context of the functional changes that occur. He established the importance of the nervous system in the development of dermatoses. Moved Permanently. The document has moved here.

The diperoxide B decomposes much more slowly to yield O 2 and CH 3ReO 3. This is a minor pathway, however, amounting to.
