Benzyl alcohol is used as a general solvent for inks, paints, lacquers, and epoxy resin coatings.It is also a precursor to a variety of esters, used in the soap, perfume, and flavor industries. It is also used as a photographic developer.
Benzyl alcohol has been used as a dielectric solvent for the dielectrophoretic reconfiguration of nanowires.
(2)Use in health care
Benzyl alcohol is used as a bacteriostatic preservative at low concentration in intravenous medications, cosmetics and topical drugs.
The use of benzyl alcohol as a 5% solution has been approved by the U.S. FDA in the treatment of head lice in children older than 6 months and in adults.
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 test has been used to determine non-destructively whether an object is truly made of quartz (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.
Function and Use:
Benzyl alcohol can be used as preservative of ointments, desiccant of fibers, nylon and plastic film, stabilizer of PVC, photographic developer, solvent of acetate fiber, inks, coatings, paints, epoxy paints, dyes, casein, gelatin, shellac and the like, and intermediate to prepare the benzyl esters or ethers. It also can be used to prepare spices and flavorings (mostly benzyl alcohol ester of fatty acids), which can be used as additive of soaps, perfume, cosmetic and other products.
Since the quartz and wool fibers have almostsame refractive index, it can be used to identificate them. In addition, it is used as fixative and diluent inperfume industry. The hydroxy of benzyl alcohol is very lively.
It can react with benzene to generate diphenyl methane, and with acrylonitrile to generate N-benzyl acrylamide (Ritter reaction). It also can react with phosphorus halide and halogen acid to generate benzyl halide. Benzyl halide and benzyl alcohol are benzylation (phenylmethyl) reagent. It can be used as benzyl-protecting group for carboxylic acid and alcohol hydroxy. Benzyl-protecting group can be removed by hydrogenation easily. In addition, benzyl alcohol can also be easily oxidized to benzoic acid by a variety of oxidants. If nitric acid is used, it can be oxidized to aldehyde or acid with different concentration and temperature.
While taking penicillin injections, benzyl alcoholis always used as anesthesia in order to prevent the patient from pain, in which conditions the pain is not too strong. So benzyl alcohol is also known as “painless water”. However, a common clinical side effect is founded: gluteus contracture disease. This is because that benzyl alcohol is not easy to be absorbed by human body. It will chronically accumulate at the injection site, and lead to necrosis of surrounding muscles. In severe cases, it may affect the growth of bone. In 2005, the state food and drug administration issued a ban on benzyl alcohol used as the solvent of penicillin injections.
