Photocatalytic Degradation of 4-Chlorophenol. 1. The Hydroquinone Pathway
Abstract
Complete mineralization of 4-chlorophenol in water can be achieved by photocatalytic degradation of oxygenated solutions containing suspended TiO 2 . The chemical pathways of this degradation are complex, and in this paper, that which begins with hydroquinone is examined. Hydroxylation to form 1,2,4-benzenetriol is the first step, though a very small amount of cleavage of the C1−C2 bond is observed. The first major group of acyclic compounds derives from oxidative cleavage of either the C1−C2 or C3−C4 bond of 1,2,4-benzenetriol. It is argued that this results from single electron oxidation and capture by superoxide. Many smaller compounds have also been identified, and routes to various ones of them are proposed. Nearly all of the compounds are verified by use of authentic samples.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
