Benzyl alcohol Liquid

Benzyl alcohol is used as antiseptic of ointment, desiccant of fiber, nylon wire and plastic film, stabilizer of PVC, photographic developer, solvent of acetate fiber, ink, coating, paint, epoxy resin coating, dye, casein, shellac and gelatin to prepare benzyl ester or ether. It is also used to produce spices and flavoring agents (mostly benzyl esters of fatty acids) as additives in soaps, perfume, cosmetics and other products. As it has almost the same refractive index as quartz and wool fiber, it can be used as an identification agent for quartz and wool fiber. The hydroxyl group of benzyl alcohol used as fixative and diluent in the fragrance industry is very active. It can react with benzene to generate diphenylmethane, with acrylonitrile to generate N-benzylacrylamide (Ritter reaction), or with phosphorus halide and hydrohalide acid to generate benzyl halide. Halogenated Chemicalbooked benzyl and benzyl alcohol are benzyl (benzyl) reagents, which are used to give benzyl protection groups to carboxylic acids and alcohol hydroxyl groups. The benzyl protecting group is easily removed by hydrogenation. In addition, benzyl alcohol is also easy to be oxidized to benzoic acid by a variety of oxidants. If nitric acid is used for oxidation, it can generate aldehyde or acid depending on the concentration and temperature. When penicillin is injected, benzyl alcohol is often used for anesthesia to prevent the patient from feeling too much pain, so that the pain will not be too strong. Therefore, benzyl alcohol is also called "painless water". However, a common side effect, gluteal muscle contracture, was quickly found in clinic. This is because benzyl alcohol is not easy to be absorbed by the human body. If it is left at the injection site for a long time, it will lead to necrosis of surrounding muscles, and even affect bone development in serious cases. In 2005, the State Food and Drug Administration issued a document forbidding the use of benzyl alcohol as penicillin solvent for injection
