Pulsed radiolysis of potassium 3-sulfolanyldithio-carbamate and sulfolane in aqueous solutions
The intermediate products of the radiolysis of potassium 3-sulfolanyldithiocarbamate and sulfolane were studied by the method of pulsed radiolysis with optical recording. It was found that the hydrated electron adds to the sulfonyl and dithiocarbamate groups to form anion radicals A and B, which have maximal absorption at /lambda//sub max/ /equals/ 600 and 315 nm, respectively. The kinetic first-order decay-rate constants of the anion radicals are equal to k/sub A/ /equals/ 7.0/centered dot/10/sup 5/ and k/sub B/ /equals/ 3.2/centered dot/10/sup 4/ sec/sup /minus/1/. It was found that there is an electron transfer from anion radical A to the dithiocarbamate electron acceptor center of the second anion radical A with the formation a trianion diradical. The rate constant of this process is higher than or equal to 8.5/centered dot/10/sup 10/ dm/sup 3//centered dot/mole/sup /minus/1//centered dot/sec/sup /minus/1/.
