hi, i founded that:
PHENOL
Molecular formula: C6H6O
CAS registry number: 108-95-2
RTEC registry number: SJ 3325000 (solid)

PHYSICAL PROPERTIES OTHER CHARACTERISTICS
----------------------------------------
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)
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.
Don't you think if I had something intelligent to say, it would bee in my post?

preferably p-benzoquinone.
This reaction doesn't work for Ph-X, and anyway, if you have that you can use if for better things.
It's good to bee back! Don't trust your computer!!
