Hydrolysis of chlorobenzene (the Dow process), https://www.britannica.com/science/phenol, Centers for Disease Control and Prevention - Phenol, National Center for Biotechnology Information - PubChem - Phenol. Is It Bad to Take Ibuprofen on an Empty Stomach? In its pure form, it may be colorless or white. The solubility behaviour of phenol and water is complicated, and beyond UK A level. Phenol-derived compounds have a variety of uses, including: Phenol liquid is often used in molecular biology with trichloromethane and chloroform to separate RNA, DNA, or proteins, and isolate them in the pure form. The crystals are often rather wet and discoloured. Thus, they are more soluble in water than are alcohols and have higher boiling points. Although this process seems more complicated than the Dow process, it is advantageous because it produces two valuable industrial products: phenol and acetone. There are hundreds of different kinds of phenols, and these contribute to the variety of plant life found on earth. Phenol is quite toxic, however, and concentrated solutions cause severe but painless burns of the skin and mucous membranes. Our website services, content, and products are for informational purposes only. Phenolics also can be used as an intermediate for industrial synthesis to make a variety of products, ranging from plastics, explosives, paints, fertilizers, textiles, aspirin and paper. It may be colorless or white and has a mild sugary odor. 8–15 g is enough for a lethal dose taken orally. . Most of this research comes from animal models, but human studies are also promising. At least one polyphenol, resveratrol, is believed to have potent anti-aging effects. Phenol can be injected into your muscles to treat a condition known as muscle spasticity. A small 2001 study of 172 people found that 98.8 percent of those who received a chemical matrixectomy with phenol cauterization had successful results. Phenol is used in some throat sprays that can help numb your throat and relieve symptoms caused by a sore throat, or irritation in the mouth caused by canker sores. For example, phenol itself is used (in low concentrations) as a disinfectant in household cleaners and in mouthwash. Read the ingredients label carefully to make sure you’re not allergic to any other components of the spray. The Dow process is somewhat more general, but the stringent conditions required often lead to low yields, and they may destroy any other functional groups on the molecule. It causes your muscles to become tight. If high levels of phenol comes into contact with the skin, Princeton University’s Environmental Health and Safety Office recommends immediately flushing the skin with large amounts of water. Phenol is a type of organic compound. It provides effective, low-cost hygiene to poverty-stricken communities. Antioxidants are incredibly important, but most people don't really understand what they are. It can be caused by conditions like Parkinson’s disease, cerebral palsy, or brain trauma. Antioxidant molecules are like a barrier between free radicals and healthy molecules: antioxidants replace the missing electron and render it harmless. A phenol injection helps limit the signals sent from your nerves to your muscles that cause contractions. Phenol-formaldehyde resins are heat-resistant and waterproof, though somewhat brittle. There is an interaction between the delocalised electrons in the benzene ring and one of the lone pairs on the oxygen atom. Phenol is somewhat soluble in water because of its ability to form hydrogen bonds with the water. Chlorobenzene is hydrolyzed by a strong base at high temperatures to give a phenoxide salt, which is acidified to phenol. Some, such as anthocyanins and flavonoids, provide coloration. In short, since the category encompasses such a broad variety of chemicals, it also encompasses a broad variety of effects on human health. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Learn more about the chemistry in the products we rely on every day, including how and why particular chemicals are used in different products, and health and safety information about these chemicals. Phenol-based products for mouth and throat pain are widely available and safe to use in small doses. The pH level of phenol helps separate the DNA and RNA. Some notable phenolic antioxidants with proven health effects include: Phenol-based compounds have been found to have some cancer prevention properties. Mildly acidic, it requires careful handling because it can cause chemical burns. Tylenol is safe when it's used according to the directions on the label. Carbolic acid was used by Joseph Lister as one of the first antiseptics to sterilize medical equipment for cleaning wounds.
