Persulfate and perphosphate oxidation of 2‐propanol: A relative rate study

Abstract

A competitive reaction study for two isoelectronic peroxides (peroxodisulfate SzOi-and peroxodiphosphate P20:-) interacting with the free radical .C(CH&OH is described. The radical formation is initiated by photolysis, the amounts of peroxide remaining analyzed volumetrically. It is found that persulfate reacts with the organic radical over 100 times more rapidly than does perphosphate. Mechanistic consequences in relation to previous work are briefly discussed.

“…2a ) appears to correspond to the adduct of such a radical intermediate ( 2 ) with SO 4 ˙ – . 24 This species has been characterized with high mass accuracy (0.8 ppm error) and closely matches the predicted isotopic distribution pattern (Fig. S4 † ) for the sulfated product.…”
