I sold the phenol is a colorless or white crystals, a special smell. When opening the package due to oxidation in air and was pink. Shandong national standard phenol (C6H6O, PhOH) phenol, also known as carbolic acid, hydroxy, is the most simple phenols, a weak acid. Many pharmaceutical uses of phenol, phenol, synthetic resin is mainly used to make dyes, plastics, synthetic fibers and pesticides, salicylic acid. Preparation of phenol by distillation of coal tar by phenol prices by acid after alkaline fusion. Chlorobenzene hydrolysis Phenol bactericide the oxidation of the cumene rearrangements Phenol: insulation materials are mainly foam Phenolic Resin Phenolic foam insulation Features, heat, fire and light, used as adiabatic energy saving, new materials fireproof central air conditioning system can be widely used, lightweight insulation color plates, house insulation can drop insulation, pipe insulation in the field of chemical insulation materials (especially cryogenic insulation), travel and other places. Phenolic foam because of its low thermal conductivity, good insulation properties, known as the king of the insulation. Phenolic foam is not only low thermal conductivity, good insulation properties, also has flame retardant, thermal stability, high light, low smoke, low toxicity, thermal, mechanical strength, noise, and strong resistance to chemical corrosion, weather and many other type of good term advantage, phenolic foam rich source of raw materials, low prices, and production and processing is simple, uses a wide range of products.
