Kinetics of reduction of sulfur dioxide by hydrogen sulfide in the presence of sulfoxides, pyridine N-oxide, trioctylphosphine oxide and tributyl phosphate
The kinetic regularities were studied of the reduction of SO/sub 2/ by hydrogen sulfide in m-xylene containing 0.025 M of aliphatic sulfoxides, (C/sub 1/-C/sub 8/alkyl), diphenyl-, dibenzyl sulfoxides, tributyl phosphate (TBP), trioctylphosphine oxide (TOPO) at 25/degree/C, and 0.001-0.003 M pyridine N-oxide (PyO) at 21-60/degree/C. It was shown that the reaction proceeds with the participation of an SO/sub 2/ complex having the composition of R/sub n/XO...SO/sub 2/ (where X = S, P, N). The kinetic regularities for the reaction taking place in the presence of aromatic sulfoxides are explainable by the contribution to the reaction of intermediate SO/sub 2/ complexes. The equilibrium constants of the complexation of SO/sub 2/ with aliphatic sulfoxides, PyO, TOPO, and TBP and the rate constant of the limiting stage of the reaction were calculated.
