C6H5-OH + H2S2O8 | ||||||
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 ? |

other fun facts to know about phenol | ||||||
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) ![]() 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? |

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. It's good to bee back! Don't trust your computer!! |
