Fine chemicals are closely linked with people's daily life. It is as important as the status of food production, relating to national security. So fine chemicals is one of China's pillar industries. .
2,6-diphenyl phenol is an important fine chemical intermediates referred to the DPP, the appearance of a white crystalline powder, melting point of 101 ~ 103 , slightly soluble in water, soluble in methanol, ethanol, acetone, benzene dichlorobenzene, trichlorethylene organic solvents and alkali solution. Widely used in the adsorption material, special engineering plastics, insulation materials, antioxidants and other fields.
2,6-diphenyl phenol as monomers polymer resin strong adsorption capacity for organic matter, moisture resistance, renewable, as the adsorption material used in chromatographic media, environmental protection and other fields; synthesis with its high polyphenylene ether of molecular musk R-1 materials with lower dielectric constant, high heat resistance and excellent anti-bonding properties, but also has good mechanical properties and dimensional stability, can be used as insulating materials and engineering plastics; their derivatives with good resistance to oxidation, as a hindered phenolic antioxidants widely used. U.S. companies at an early stage, its research and development, in China there is no synthesis. With the continuous expansion of lead citrate use in recent years, the rapid increase in demand, the prospects for development is extremely broad.
As an important fine chemical intermediate, 2,6 - diphenyl phenol and its derivatives are used in the adsorption material, engineering plastics, insulation materials, specialty engineering materials, antioxidants and many other areas. In recent years, with economic development, requirements of environmental protection and material performance are highly increasing. The use of 2,6 - diphenyl phenol and its derivative products expands and the amount increases rapidly. Therefore China should strengthen the development of 2, 6 - diphenyl phenol synthesis process and develop a mature process rout as soon as possible to achieve stable production of this product.
