Applicaton of o-phenylphenol

Used as a carrier for hydrophobic synthetic fibers such as chlorinated fiber and polyester when using Vector staining method, surfactants, bactericidal preservatives, and dye intermediates. In Japan, 2-Phenylphenol and it’s sodium salt are used for citrus mildew prevention. Mix 0.8% of this product in the wax and spray it on the harvested Citrus.It can also be used together with biphenyl to minimize the rots. The range of fruits allowed in the United Kingdom, United States, and Canada is relatively larger, including apples, pears, and pineapples. The product is also used in cosmetics as a preservative.

Ortho-phenylphenol is an organic chemical product with a very wide range of uses. It is widely used in the fields of sterilization and corrosion protection, printing and dyeing auxiliaries and surfactants, as well as stabilizers and flame retardants for the synthesis of new plastics, resins and polymer materials. Its specific uses are as follows:

Antiseptic and antiseptic:

O-Phenylphenol and its sodium salt have high weed-killing activity, and have broad-spectrum bactericidal and mildew-removing ability, and with low-toxicity and tasteless. They are good preservatives and can be used for anti-mould and fresh-keeping of fruits and vegetables, especially for mildew preventing of the Citrus ,also can used to treat lemons, pineapples, melons, fruits, pears, peaches, tomatoes, cucumbers, etc., to minimize the rot. Countries such as the United Kingdom, United States, and Canada are allowed to use a wider range of fruits, including apples.

Ortho-phenylphenol and its sodium salt can be used as preservatives and fungicides in cosmetics, wood, leather, fiber and paper, etc. The general use concentration is 0.15-1.5%. The U.S. Environmental Protection Agency (EPA) allows the use of nearly two hundred varieties of Bactericidal soup, Sterilizing and deodorizing lotion lotions, and antiseptic preservatives with o-phenylphenol or its sodium salt as the main ingredient, and it is considered that these products are non-toxic , the annual consumption of o-phenylphenol exceeds 1 million pounds only in this field.

Dyeing carrier for synthetic fibers:

Ortho-phenylphenol and its water-soluble sodium salt can be used as a dye carrier for polyester fibers,and also used as a carrier for hydrophobic synthetic fibers such as chlorinated fiber and polyester when using Vector staining method.

Synthesis of new phosphorus-containing flame-retardant materials:

When the polymer material containing Organophosphorus compounds is burned, it will form a Graphite carbonized film on the surface of the material to isolate the polymer from the air. It has good flame-retardant properties, high flame-retardant efficiency, low volatility,  good oil and hydrolysis resistance .It has good performance and is more and more widely used, and will gradually replace the inorganic and halogen-containing flame-retardant materials used today. Using o-phenylphenol as raw material, a new type of phosphorus-containing flame-retardant intermediate DOPO can be synthesized.
