O-phenylphenol (OPP) is an important new type of fine chemical products and organic intermediates. It is widely used in the fields of sterilization, anti-corrosion, printing and dyeing auxiliaries, surfactants, stabilizers and flame retardants of new plastics, resins and polymer materials.
O-phenylphenol is mainly used to prepare o-phenylphenol formaldehyde resin, and to prepare varnish with excellent water and alkali stability. This varnish has strong durability and weather resistance, especially suitable for wet and cold weather and marine ships.
Opp is a good preservative, can be used for fruit and vegetable mildew prevention, can also be used to treat lemon, pineapple, melon, pear, peach, tomato, cucumber, can reduce the rot to the minimum. The United Kingdom, the United States and Canada are allowed to use a wide range of fruits, including apples, pears, pineapples, etc.
A chlorinated derivative of o-phenylphenol, 2-chloro-4-phenylphenol, used as a herbicide and disinfectant, and as a fungicide for the control of fruit tree diseases. O-phenylphenol was sulfonated and condensed with formaldehyde to form dispersant for pesticide.
The preparation of 2-chloro-4-phenylphenol from OPP can be used as herbicide and disinfectant, OPP can be used to produce non-ionic emulsifier and synthetic dyes, o-phenylphenol and its water-soluble sodium salt can also be used as dye carrier for polyester fiber, triacetic acid fiber, etc,
(1) Synthesis of flame retardant polyester
Dop0 was used as raw material to react with itaconic acid to form an intermediate, odop-bda, which can partly replace ethylene glycol to obtain a new phosphorus containing flame retardant polyester.
(2) Synthesis of flame retardant epoxy resin
Epoxy resin is widely used in adhesives, electronic instruments, aerospace, coatings and advanced composite materials due to its excellent adhesion and electrical insulation properties. In 2004, the consumption of epoxy resin in the world reached more than 200000 tons / year.
(3) Improving the organic solubility of polymers
(4) As an intermediate in the synthesis of antioxidant
(5) Stabilizers for synthetic polymer materials
(6) Synthetic luminescent parent
