Description of Benzyl alcohol

Benzyl alcohol is an aromatic alcohol with the formula C6H5CH2OH. The benzyl group is often abbreviated “Bn” (not to be confused with “Bz” which is used for benzoyl), thus benzyl alcohol is denoted as BnOH. Benzyl alcohol is a colorless liquid with a mild pleasant aromatic odor. It is a useful solvent due to its polarity, low toxicity, and low vapor pressure. Benzyl alcohol is partially soluble in water (4g/100mL) and completely miscible in alcohols and diethyl ether. The anion produced by deprotonation of the alcohol group is known as benzylate or benzyloxide.

What is Benzyl alcohol?

Part I: Introduction

With the development of technology and social progress, machinery, medicine, cosmetics, electronics, ceramics, glass, etc. are all-pervasive in people’s daily lives. One of these products is benzyl alcohol, which is widely used in some fields.

The official answer: benzyl alcohol, also known as benzyl alcohol, molecular formula C6H5CH2OH, density 1.045 g/mLat25°C (lit.), is the simplest fatty alcohol containing phenyl, which can be regarded as hydroxymethyl substituted benzene, or phenyl substituted methanol. It is a colorless, clear, viscous liquid with a faintly aromatic odor, sometimes with a slightly bitter almond smell of benzaldehyde due to oxidation when benzyl alcohol is left for a long time. It is polar, low in toxicity, and has a low vapor pressure, which is why it is used as an alcohol solvent.

Where are the main areas of application for benzyl alcohol?

Part II: In-depth development

Benzyl alcohol is an extremely useful fragrance fixing agent and is indispensable in the preparation of jasmine, under-the-moon, and ylang-ylang fragrances. It is used in the formulation of soaps; daily make-up fragrances. But benzyl alcohol can be slowly natural oxidation, part of the generation of benzaldehyde and benzyl ether, so that commercially available products often with almond fragrance, so should not be stored for a long time. Benzyl alcohol is widely used in the production of industrial chemicals. It is used as a solvent for paints; a photographic developer; a stabilizing Chemicalbook agent for polyvinyl chloride; a pharmaceutical; a solvent for synthetic resins; a solvent for vitamin b injections; and a preservative for ointments or pharmaceutical solutions. It can be used as nylon silk; desiccant for fiber and plastic film, dye; cellulose ester; solvent for casein, intermediate for making benzyl ester or ether. It is also widely used in the production of pens (biros oil); paint solvents, etc. GB2760–1996 stipulates that it is temporarily allowed to be used as an edible spice.

Benzyl alcohol is used as a preservative for ointment, desiccant for fiber, nylon silk and plastic film, stabilizer for polyvinyl chloride, photographic developer, solvent for acetate, ink, paint, paint, epoxy resin paint, dyestuff, casein, shellac, and gelatin, intermediate for making benzyl ester or ether. It is also used to make fragrances and flavorings (mostly benzyl alcohol esters of fatty acids) for use as additives in soaps, perfumes, cosmetics, and other products. Used as a discriminator between quartz and wool fibers as it has almost the same refractive index as quartz and wool fibers. The hydroxyl group of benzyl alcohol is very active in the fragrance industry and it can react with benzene to form diphenylmethane, with acrylonitrile to form N-benzylacrylamide (Ritter reaction), and with phosphorus halides and hydrohalic acids to form benzyl halides. Both benzyl halochemicalbook and benzyl alcohol are benzyl (phenylmethyl) chemistry reagents used to give benzyl protecting groups to carboxylic acid and alcohol hydroxyl groups. The benzyl protecting group is easily removed by hydrogenation. In addition, benzyl alcohol is also readily oxidized to benzoic acid by a variety of oxidizing agents, which, if oxidized with nitric acid, can produce either an aldehyde or an acid, depending on the concentration and temperature. When penicillin is injected, benzyl alcohol is often used as an anesthetic to prevent the patient from feeling too much pain, so that the pain is not too intense, hence the name “painless water”. However, a common clinical side effect was soon discovered: gluteus contracture. In 2005, the State Drug Administration banned the use of benzyl alcohol as a solvent for penicillin injections.

WHY THEY SAY TO US

Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
