Description

The dissertation deals with the radiation chemistry of aqueous solutions of sodium-dimethyl phosphate (CH3O)2P(O)O-Na+, (DMP), with the intention to get more detailed information about the mechanism of the radical phosphate ester fission by this simple model substance. In order to find out the mechanism of the fission of the C-OPO3 binding, the product formation was followed up after the gamma-irradiation of DMP in aqueous solutions. Moreover it was possible by applying the pulse radiolysis to observe the absorption spectra of radical intermediate products and to investigate the kinetic phenomena of their disappearance.

Abstract (German)

Die Arbeit befasst sich mit der Strahlenchemie waessriger Loesungen des Natriumdimethylphosphats, (CH3O)2P(O)O-Na+, (DMP), mit dem Ziel, naeheres ueber den Mechanismus der radikalischen Phosphatesterspaltung an dieser einfachen Modellsubstanz zu erfahren. Um den Mechanismus der Spaltung der C-OPO3-Bindung aufzuklaeren, wurde die Produktbildung nach der γ-Bestrahlung von DMP in waessrigen Loesungen verfolgt. Daneben wurde es durch Anwendung der Pulsradiolyse moeglich, die Absorptionsspektren von radikalischen Zwischenprodukten zu beobachten und die Kinetik ihres Verschwindens zu untersuchen. (orig./HK)
