Περιγραφή:

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, αιθυλαιθέρας, benzene, chloroform and other organic solvents.

Χρήση:

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. Εξάλλου, 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.

Εξάλλου, 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.

Εφαρμογή :

1. Benzyl alcohol is a good middle boiling point solvent,it is widely used for additive to steroid when making into solution.

2. The main applications:paint solvent; ink solvent; plexiglass solvent; photographic developing agent; PVC stabilizer; medicine, synthetic resin solvent; ointment or liquid medicine; solvent for meat products tamp-pad ink and ball-point pen oil.

3. It is used for carpet degreaser; crater cleaning agent; silicone solvent stabilizer; benzyl ester or ether intermediate.

4. Benzyl alcohol is a kind of very useful perfume fixative. It is an indispensable spice when jasmine, tuberose or ylang is mixed, and used to compound soap and daily cosmetics.

5. Benzyl alcohol is used as a general solvent for inks, paints, lacquers, and epoxy resin coatings.

6. 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.
