Basic Info

Preparation method

There are mainly separation methods and synthesis methods. The synthesis method includes phenol coupling method, cyclohexanone condensation dehydrogenation method, biphenyl sulfonation hydrolysis method, etc. Among them, cyclohexanone condensation dehydrogenation method is more widely used.

Uses

Sterilization and antiseptic: 2-Phenylphenol has a broad spectrum of sterilization and mold removal capabilities, and can be used for the anti-mold preservation of fruits and vegetables, such as citrus, apples, pears, etc., and can also be used for the antiseptic of wood, leather, paper, etc.
Dyeing carrier: It and its water-soluble sodium salt can be used as a dye carrier for polyester fibers, and is also a carrier for hydrophobic synthetic fibers such as chloroprene and polyester when dyed with carriers.
Flame retardant materials: Using o-phenylphenol as a raw material, a new type of phosphorus-containing flame retardant intermediate DOPO can be synthesized, which is used for flame retardant polyester, epoxy resin, etc.
Others: It can be used to synthesize a developer for synthesizing pressure-sensitive and heat-sensitive paper; reacting with BCl₃ can obtain antioxidants and anti-fatigue agents for lubricating oils; reacting with glycerol to obtain compounds, which can be used for fiber modification, etc.
