Beschreibung:
Benzyl alcohol is an aromatic alcohol with the formula C6H5CH2OH. The benzyl group is often

abbreviated “Bn” (not to be confused with “Bz” which is used for benzoyl), thus benzyl alcohol is

denoted as BnOH. Benzyl alcohol is a colorless liquid with a mild pleasant aromatic odor. Es ist ein

useful solvent due to its polarity, geringe Toxizität, and low vapor pressure. Benzyl alcohol is partially

in Wasser löslich (4 g/100 mL) and completely miscible in alcohols and diethyl ether.

Benzyl alcohol is produced naturally by many plants and is commonly found in fruits and teas. es ist

also found in a variety of essential oils including jasmine, hyacinth, and ylang-ylang.It is also one

of the chemical compounds found in castoreum. This compound is gathered from the beaver

plant food.

Benzyl alcohol has nearly the same refraction index of quartz and wool fibre. If a clear quartz

object is immersed in benzyl alcohol, it becomes almost invisible. This has been used as a

method to non-destructively recognize if an object is made of true quartz or not (see crystal skull).

Similarly, white wool immersed in benzyl alcohol also becomes almost invisible clearly revealing

contaminants such as dark and medullated fibres and vegetable matter

Benzyl alcohol is only a mild acute toxin with an LD50 of 1.2 g/kg in rats. It oxidizes rapidly in

healthy individuals to benzoic acid, conjugated with glycine in the liver, and excreted as hippuric

acid. Very high concentrations can result in toxic effects including respiratory failure, vasodilation,

hypotension, convulsions, and paralysis.

Benzyl Alcohol is often the primary solvent and sometime the only solvent in a given formula. Es ist

primary function is as a sterilizing agent. jedoch, due to its solvency power it is often used to

keep hormones in solution with oil or other vehicles. It is also one of the thinnest (that is best for

viscosity reduction) The major drawback to this solvent is that it tends to make for painful

injections if the concentration goes above 10%. (This is true for any low molecular weight

alcohol). Less than this tends to be painless for most people.

Anwendung:
Benzyl alcohol used as ointment’s preservatives, fiber, nylon and plastic film’s desiccant, PVC

stabilizers, photographic developer, solvent of acetate fiber, ink, paint, paint, epoxy resin coating,

dye, such as gelatin, casein, shellac , intermediate for preparing benzyl ester or ether. Also used

for preparing spices and flavoring agent ,additives to soap, perfume, cosmetics and other

Produkte. Because of index and quartz and wool fiber having nearly the same refractive , so as to

identify agents of quartz and wool fiber. In perfumery industry used as a fixative and diluent.
