C6H5-OH + H2S2O8

hi, i founded that:

    PHENOL

                          Molecular formula: C6H6O
                       CAS registry number: 108-95-2
                  RTEC registry number: SJ 3325000 (solid)

    Relative molecular mass          94.11                White crystalline solid turning pink or red when
    Melting point (°C)               40.9                 exposed to air and light; burning taste and
    Boiling point (°C)               181.75               distinctive odour; the compound reacts moderately
    Water solubility (g/litre)       67                   fast with oxidizing agents and violently with
    Specific density (25°C)          1.071                butadiene, peroxydisulfuric acid, peroxymono-

    Vapour pressure (kPa) (20°C)     0.04 (0.357 mmHg)    benzene; when heated or burning the compound
    Ignition temperature (°C)        715                  emits toxic fumes; the compound is extremely
    Flash point (closed cup) (°C)    80                   destructive to mucous membranes, skin, and eyes
    Flammability (explosive)                              and may be fatal if inhaled, swallowed, or absorbed
      limits (vol. %)                1.3-9.5              through the skin

what is the reaction between Ph-OH and H2S2O8 ?
i guess Ph-X reacts same way ?

Disposition in the Body.Rapidly absorbed from the gastrointestinal tract and readily penetrates the skin. It is metabolised by conjugation to yield phenyl glucuronide and phenyl sulfate; small amounts are oxidised to catechol and quinol which are also conjugated. Oxidation of these metabolites to quinones may tint the urine green.(hehehe) ;D  Acid–labile phenol conjugates are present endogenously in serum at concentrations of about 0.1 mg/L. Phenol is a metabolite of benzene. Endogenous phenol concentrations in urine average about 5 to 10 mg/L.
Toxicity.Phenol denatures and precipitates cellular proteins and thus may cause rapid poisoning. The minimum lethal dose by mouth is about 1 g. Severe and even fatal poisoning may also arise from absorption of phenol from open wounds or through the intact skin. The maximum permissible atmospheric concentration is 5 ppm.

It gets oxidized to quinones

preferably p-benzoquinone.

This reaction doesn't work for Ph-X, and anyway, if you have that you can use if for better things.
