Phenol solution Phenol, also known as carbolic acid and hydroxybenzene, is the simplest phenolic organic matter and a weak acid. It is a colorless crystal at normal temperature and toxic. Phenol is a common chemical and an important raw material for producing some resins, fungicides, preservatives and drugs (such as aspirin). Phenol is corrosive, slightly soluble in water at room temperature and easily soluble in organic solutions; When the temperature is higher than 65℃, it can be miscible with water in any proportion. Its solution can be washed with alcohol when it touches the skin, and phenol is pink when exposed to air. It can absorb moisture in the air and liquefy it. No special smell, extremely dilute solution has sweet taste. Very corrosive. Strong chemical reaction ability. Reacting with aldehydes and ketones to produce phenolic resin, bisphenol A and acetic anhydride; Salicylic acid reacts to produce phenyl acetate and salicylate. Halogenation, hydrogenation, oxidation, alkylation, carboxylation, esterification and etherification can also be carried out. Phenol is a solid at normal temperature, which can't react smoothly with sodium. If the method of melting phenol by heating and adding metallic sodium is used in the experiment, phenol will be easily reduced, and the color of phenol will change when heating, which will affect the experimental effect.
