Uses

1.Benzyl alcohol can be used as raw materials and fixatives of spice, pharmaceutical raw materials and anesthetics, preservatives, coloring additives, coatings and solvent of inks. It also can be used to make ballpoint oil.
2.It can be used as chromatographic analysis reagent. And it also can be used in organic synthesis.
3.It can be used for the preparation of sesame oil, drugs and the like. It also can be used as the solvent and fixatives of spice.
4.Benzyl alcoholexists in many fragrant essential oils. Then it can be used as condensing agent with benzyl acetate in jasmine, gardenia, lilac, ylang-ylang, tuberose, hyacinth, acacia and other floral type. It has the fixative effect too. It is often used as the solvent to dissolve artificial musk and other spices. In addition, it can be used as food spices inedible flavor, like cherries, grapes, honey, orange, raspberry, walnut, vanilla.
5.Benzyl alcohol is the edible spice that is temporarily allowed to use. It is mainly used in almonds, oranges, cherries, grapes, strawberries and other fruit-based flavor. The dosage of benzyl alcohol is as the normal production needs. It is usually 1200mg/kg in the chewing gum, 220mg/kg in baked foods, 160mg/kg in cold drinks, 47mg/kg in the candy, and 15mg/kg in soft drinks.
6.Benzyl alcohol is a very useful fixative. It is the indispensable spices to allocate jasmine, polianthes tuberosa, ylang-ylang and other flavorings. It can be used to prepare soaps and daily cosmetics flavorings. But benzyl alcohol can be naturally and slowly oxidized. Part of benzyl alcohol will be oxidized to benzaldehyde and benzyl ether, which makes commercial products with almond scent. It should not be stored for a long time. Benzyl alcohol is widely used in the production of industrial chemicals. It can be used as coating solvent, photographic developer, PVC stabilizer, medicine, solvent of synthetic resin, solvent of vitamin B injection, preservative of unguent or liquid. It also can be used as desiccant of nylon, fiber and plastic film, solvent of dye, cellulose ester and casein, intermediate to prepare benzyl esters or ethers. Meanwhile, it is widely used as pen oil, paint solvent, etc.
7.GB 2760--1996 stipulates that benzyl alcohol can be used as food spices temporarily. It also can be used as fixative agent and grease solvent. As spices, it is mainly used for the preparation of berries, nuts and other flavors.
8.It can be used in organic synthesis. It can be used as solvent of gelatin, casein (heat), cellulose acetate and shellac and the like, microscope embedding material. It also can be used to determinate the contents of vitamin B12.

Air & Water Reactions

Slightly soluble in water.

storage

Benzyl alcohol oxidizes slowly in air to benzaldehyde and benzoic acid; it does not react with water. Aqueous solutions may be sterilized by filtration or autoclaving; some solutions may generate benzaldehyde during autoclaving.
Benzyl alcohol may be stored in metal or glass containers. Plastic containers should not be used; exceptions to this include polypropylene containers or vessels coated with inert fluorinated polymers such as Teflon.
Benzyl alcohol should be stored in an airtight container, protected from light, in a cool, dry place.
