Phenol Specification

The Phenol, monohydroxy derivative of benzene, is an organic compound with the chemical formula C6H5OH. It has the EINECS register number 203-632-7 and CAS register number 108-95-2. Phenol is appreciably soluble in water, with about 8.3 g dissolving in 100 mL (0.88 M). In addition, Phenol is a colourless crystals with a characteristic odour. It is stable which should be protected from strong oxidizing agents, strong bases, strong acids, alkalies and calcium hypochlorite. Phenol is flammable which may discolour in light. 

Physical properties about Phenol are: (1)ACD/LogP: 1.54; (2)ACD/LogD (pH 5.5): 1.54; (3)ACD/LogD (pH 7.4): 1.54; (4)ACD/BCF (pH 5.5): 8.72; (5)ACD/BCF (pH 7.4): 8.69; (6)ACD/KOC (pH 5.5): 164.00; (7)ACD/KOC (pH 7.4): 163.44; (8)#H bond acceptors: 1; (9)#H bond donors: 1; (10)#Freely Rotating Bonds: 1; (11)Index of Refraction: 1.553; (12)Molar Refractivity: 28.134 cm3; (13)Molar Volume: 87.863 cm3; (14)Polarizability: 11.153 10-24cm3; (15)Surface Tension: 40.9669990539551 dyne/cm; (16)Density: 1.071 g/cm3; (17)Flash Point: 72.475 °C; (18)Enthalpy of Vaporization: 43.524 kJ/mol; (19)Boiling Point: 181.839 °C at 760 mmHg; (20)Vapour Pressure: 0.614000022411346 mmHg at 25°C

Preparation of Phenol: Phenol has been made, over the years, by a variety of processes. Historically, an important method was the sulfonation of benzene followed by desulfonation with caustic soda:

C6H6 + H2SO4 → C6H5SO3H + H2O
C6H5SO3H + 2 NaOH → C6H5OH + Na2SO4

The above route to Phenol has no longer used. The principal process in use is the peroxidation of cumene (iso-propylbenzene) at 130 °C in the presence of air and a catalyst followed by decomposition of the peroxide at 55 to 65 °C in the presence of sulfuric acid. In the cumene process, cumene is oxidized to form cumene hydroperoxide that is then concentrated and cleaved to produce phenol and acetone. By-products of the oxidation reaction are acetophenone and dimethyl benzyl alcohol, which is dehydrated in the cleavage reaction to produce alpha-methylstyrene.

C6H6 + CH2=CH-CH3 → C6H5CH(CH3)2
C6H5CH(CH3)2 + O2 → C6H5C(CH3)2OOH
C6H5C(CH3)2OOH [H2SO4]→ C6H5OH + CH3COCH3

The toluene-benzoic acid process of preparation of Phenol involves three chemical reactions: (l) oxidation of toluene to form benzoic acid, (2) oxidation of benzoic acid to form phenyl benzoate, (3) hydrolysis of phenyl benzoate to form phenol.

2 C6H5CH3 + 3 O2 → 2 C3H5CO2H + 2 H2O
4 C6H5CO2H + O2 → 2 C6H5CO2C6H5 + 2 H2O + 2 CO2
C6H5CO2C6H5 + 2 OH- → 2 C6H5OH + CO2

Uses of  Phenol: Phenol was widely used as an antiseptic, especially as Carbolic soap. Phenol is also used in the preparation of cosmetics including sunscreens, hair dyes, and skin lightening preparations. The major uses of Phenol involve its conversion to plastics or related materials. Condensation with acetone gives bisphenol-A. Phenol is also used as an oral anesthetic/analgesic, commonly used to temporarily treat pharyngitis. Phenol is also a versatile precursor to a large collection of drugs, most notably aspirin but also many herbicides and pharmaceuticals. Phenol is one of the chemicals for embalming bodies for study because of its ability to preserve tissues for extended periods of time.

When you are using Phenol, please be cautious about it. Phenol is toxic, harmful, corrosive and highly flammable. There will be a danger of serious damage to health by prolonged exposure through inhalation, and in contact with skin and if swallowed. In addition, Phenol is toxic by inhalation, in contact with skin and if swallowed. What's more, there is a danger of very serious irreversible effects through inhalation, in contact with skin and if swallowed. In case of contact with eyes, you should rinse immediately with plenty of water and seek medical advice. Whenever you will contact Phenol, you should wear suitable protective clothing, gloves and eye/face protection. In case of accident or if you feel unwell, you can seek medical advice immediately (show label where possible). Meanwhile, you must avoid contact with skin and eyes.
