Physical and chemical properties of phenol, phenol melting point of 40.5 ℃, boiling point is 181.7 ℃, at room temperature, a colorless or white crystalline phenol prices, there is a special smell. Phenol density than water, slightly soluble in cold water, in water to form a white cloudy; but soluble in hot water above 65 ℃. Soluble in alcohol, ether and other organic solvents. Phenol molecule by a hydroxy group directly attached to the benzene ring. According Kekule type phenol fungicide benzene, the hydroxyl group is attached to the double bond of phenol excreta disposal, as enol structure. However, due to the stability of the benzene ring, such a structure is hardly converted to the keto form phenol bisphenol A: an amine curing agent for epoxy adhesives accelerator, the reference amount of 3 to 5 parts. Also with polyethylene polyamine heating the reaction of modified epoxy curing agent. Also used as epoxy flexibilizer. Phenol excreta disposal, Jiaonan phenol, Wei Wei Connaught Chemical provided by Qingdao Sino Chemical Co. Qingdao Wei Connaught Chemical Co.
