The radiolysis of hydrogen sulphide in the presence of butadiene-1, 3 and carbon tetrachloride

Abstract

The γ-radiolysis of hydrogen sulphide in the presence of : utadiene and carbon tetrachloride was studied. Addition of butadiene causes the slow diminishing in G(H₂) and sharp lowering in G(S) from 7.1 for pure H₂S down to 0.8 at all the used concentrations of butadiene. When carbon tetrachloride is added to hydrogen sulphide, G(H₂) is not changed but G(S) increases by ΔG(S) ≈ 2. The presence of butadiene and carbon tetrachloride together allows to the same change in G(H₂) as in the case of butadiene alone and lowering I(S) to zero. The ionic mechanism of molecular sulphur formation is proposed, consistent with the observed experimental facts.
