I. Application direction and field
1. In the field of sterilization and preservative: O-Phenylphenol and its sodium salt have high weed-eliminating activity and possess broad-spectrum antibacterial and antifungal capabilities. They are non-toxic and odorless, making them excellent preservatives. They can be widely used for mold prevention and freshness preservation of fruits and vegetables, such as oranges, lemons, pineapples, melons, pears, peaches, tomatoes, and cucumbers, reducing the degree of spoilage to a minimum after use. They can also be used for sterilization and preservative purposes in leather, paper, wood, cosmetics, food packaging, and more. Additionally, they can be synthesized into disinfectants for long-term use in homes, hospitals, and other settings.
2. In the field of dyeing auxiliaries and surfactants: O-Phenylphenol and its sodium salt can serve as dyeing carriers for polyester fibers and hydrophobic synthetic fibers such as acrylic and polyester, significantly enhancing the colorfastness of fibers. Additionally, O-Phenylphenol improves the swelling properties of fibers and enhances their wrinkle resistance, making it widely used in the production processes of dyeing agents, surfactants, and dye intermediates.
3. In the field of synthesizing new plastics, resins, and polymers: Using O-Phenylphenol as the raw material, new phosphorus-containing flame retardant intermediates DOPO can be synthesized. DOPO and its derivatives can be used to produce new phosphorus-containing flame-retardant polyesters, flame-retardant epoxy resins, and nylon materials with better thermal stability and flame retardancy. Additionally, O-Phenylphenol can also serve as a reactive diluent for synthetic resins and a fiber modifier. The new polymers synthesized from it can be used to prepare paints with excellent water and alkali resistance, or to manufacture high-end optical instruments and eyewear.
4. Pharmaceutical field: O-O-Phenylphenol as a drug intermediate, can be used to synthesize cholesterol ester hydrolysis inhibitor, antispasmodic drugs, anti-inflammatory drugs and analgesics and some skin disease drugs.
5. Battery field: In button batteries, O-Phenylphenol as an additive can effectively improve battery performance and prolong battery life, while reducing environmental pollution. Due to its good photoelectric properties, it can also be used as a positive electrode active material to prepare rechargeable batteries, and can also act as a sensitizer in renewable energy.
6. Optical Film Field: O-Phenylphenol plays a crucial role in the production of optical films. Adding O-Phenylphenol to the coating material formula can effectively improve the film-forming properties of the coating, making the surface of the optical film smoother and flatter, reducing internal defects and impurities in the film layer. This not only enhances the transparency of the optical film but also reduces light scattering loss within the film layer. Additionally, it improves the consistency of light transmittance across different wavelengths, thereby enhancing the image clarity and color reproduction of display devices. It is widely used in optical films for various display technologies, such as liquid crystal displays (LCDs) and organic light-emitting diode displays (OLEDs).
7. Other Applications: O-Phenylphenol can absorb ultraviolet light and emit fluorescence in the visible spectrum, making material surfaces appear whiter and enhancing visual effects. It effectively resists the degradation of materials by sunlight, ensuring product quality stability. Therefore, it is widely used in paper, plastics, wool textiles, and coatings. Additionally, it can kill bacteria and inhibit the growth and reproduction of microorganisms, extending the shelf life of goods, improving product quality, and ensuring the safety, hygiene, and quality stability of contents within packaging. It is also used as a developer in synthetic pressure-sensitive and thermal paper, an antioxidant in lubricating oils, and an anti-fatigue agent.
