Phthanophenol, for white flaky crystals, is an important new fine chemical products and organic intermediates, widely used in sterilization, anti-corrosion, printing and dyeing aids and surfactants, synthesis of new plastics, resins and polymer materials stabilizers and flame retardants and other fields, its specific uses are as follows:
Anti-corrosion sterilization
Because phthalatephenol and its sodium salt removal activity is very high, and has a broad spectrum of sterilization and mold removal capacity, and non-toxic tasteless, is a better preservative, can be used for fruit and vegetable anti-mold preservation, especially for citrus mold, can also be used to handle lemon, pineapple, melon, fruit, pears, peaches, tomatoes and cucumbers, can reduce decay to a minimum.
Staining carrier
Phthaluton phenol and its water-soluble sodium salt can be used as a dye carrier for polyester fiber, and can also be used as a carrier for hydrophobic synthetic fiber sleight of blue, polyester and so on when using carrier dyeing.
Flame retardant materials
Because the polymeric material containing the machine phosphorus compound in combustion, will form a graphite-like carbonized film on the surface of the material, so that the polymer from the air isolation, with good flame retardant properties, high flame retardant efficiency, and low volatility, oil and hydrolysis good, more and more widely used, and will gradually replace the current use of inorganic and halogen-containing flame retardant materials. With phthalatephenolas as raw material, a new phosphorus-containing flame retardant intermediate DOPO can be synthesized
