Benzyl alcohol is an organic compound with the formula C6H5CH2OH. With the cas number 100-51-6, it is also called (Hydroxymethyl)benzene;alcoolbenzylique;Bentalol;benzalalcohol;Benzalcohol;Benzenemethan-lo;benzenmethanol;Benzoyl alcohol. Benzyl Alcohol is an aromatic alcohol used as a preservative, as the active ingredient in head lice treatment, and as a solvent. It is most often created by combining benzyl chloride (a suspected carcinogen that has been used as a war gas) with sodium hydroxide (lye).
Physical properties about Benzyl alcohol are: (1)ACD/LogP: 1.055; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 1.06; (4)ACD/LogD (pH 7.4): 1.06; (5)ACD/BCF (pH 5.5): 3.73 ; (6)ACD/BCF (pH 7.4): 3.73; (7)ACD/KOC (pH 5.5): 89.37 ; (8)ACD/KOC (pH 7.4): 89.37; (9)#H bond acceptors: 1; (10)#H bond donors: 1; (11)#Freely Rotating Bonds: 2; (12)Index of Refraction: 1.546; (13)Molar Refractivity: 32.704 cm3; (14)Molar Volume: 103.25 cm3; (15)Polarizability: 12.965 10-24cm3; (16)Surface Tension: 40.7179985046387 dyne/cm; (17)Density: 1.047 g/cm3; (18)Flash Point: 97.507 °C ; (19)Enthalpy of Vaporization: 46.614 kJ/mol; (20)Boiling Point: 204.699 °C at 760 mmHg; (21)Vapour Pressure: 0.158000007271767 mmHg at 25°C
Preparation of Benzyl Alcohol: Benzyl alcohol is produced naturally by many plants and is commonly found in fruits and teas. It is also found in a variety of essential oils including jasmine, hyacinth, and ylang-ylang. Benzyl alcohol is prepared by the hydrolysis of benzyl chloride using sodium hydroxide:
C6H5CH2Cl + NaOH → C6H5CH2OH + NaCl
It can also be prepared via a Grignard reaction by reacting phenylmagnesium bromide (C6H5MgBr) with formaldehyde, followed by acidification.
Uses of Benzyl Alcohol: Benzyl Alcohol (CAS NO.100-51-6) is used as a bacteriostatic preservative at low concentration in intravenous medications. It is also used as a general solvent for inks, paints, lacquers, and epoxy resin coatings.In organic synthesis, benzyl esters are good protecting groups due to they can be removed by mild hydrogenolysis. Besides Benzyl alcohol has been used as a dielectric solvent for the dielectrophoretic reconfiguration of nanowires. Moreover it is also a precursor to a variety of esters, used in the soap, perfume, and flavor industries. It is often added to intravenous medication solutions as a preservative because of its bacteriostatic and antipruritic properties. At last it is also used as a photographic developer.
When you are using this chemical, please be cautious about it as the following:
1. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice;
2. Wear suitable protective clothing and gloves;
3. Avoid contact with skin and eyes;
4. Do not breathe gas/fumes/vapor/spray (appropriate wording to be specified by the manufacturer);
5. Avoid exposure - obtain special instruction before use;
