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-
Relative vapour density 3.24 sulfuric acid, and aluminium chloride + nitro-
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.

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