Description:


Phenylcarbinol is also known as benzyl alcohol. Its density is 1.045 g/mL at 25 ° C (lit). Benzylalcohol is one of the simplest fatty alcohol containing phenyl. It can be seen as benzene substituted by hydroxymethyl, or methyl alcohol substituted by phenyl. It is a colorless transparent sticky liquid with faint aroma. Sometimes benzyl alcohol is placed for a long time, it will smells like bitter almond flavor because of oxidation. Polarity, low toxicity and low steam, so it is used as alcohol solvent. It is combustible, and slightly soluble in water (about 25ml of water soluble 1 gram of benzyl alcohol).It is miscible with ethanol, ethyl ether, benzene, chloroform and other organic solvents.

 

Usage:


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.
