1. Fungicides: fruit and vegetable preservative. It is mainly used for the treatment of citrus epidermis mold.
2. For the European Economic Community countries and the United States, in addition to be applied citrus, can still use it for cucumber, carrot, apple, melon, tomatoes and so on. Japan is limited to citrus with the maximum residue 0.01g/kg (1990).
3. The usage condition of each country is as follows (allowable amount, mg/kg) Canadian cherry, 5; citrus, cucumber, pepper, pineapple, tomato, 10; sweet potato, 15; carrot, peach, plum fruit, 20; ; Melon, 12. European citrus, 12. Dutch citrus, 10. English citrus, 70; apple, pear, pineapple, 10; melon, 125. Orange, pepper, pineapple, tomato, sweet potatoes, 15; carrots, peaches, plums, pears, pears, pears, pears, pears, pomegranates, citrus, cucumber, grapefruit: 20; apple, pear, 25; Roman melon, 125 (edible part ≤10).
4. Usage method: The goods is embedded into wax at about 0.8% with spray or dipping way for treatment, being able to prevent the corruption caused by the Gectricnumdidum. This product is of the best efficacy with biphenyl. For the treatment of mildew caused by P. digitation in citrus, 60.% of the untreated product was moldy in about 3 to 5 weeks while only 3.4% of the treated product became moldy finally.
5. 2-Phenylphenol can be used as antiseptic fungicide. China provides that it can be used for citrus preservation with the maximum usage amount of 3.0g/kg and the residue amount being not greater than 12 mg/kg.
6. As antiseptic fungicide, the provisions of China can also be used for citrus preservation, the maximum use of 3.0g/kg and residue being not greater than 12mg/kg.
7. 2-Phenylphenol is used for strong bactericidal function, being used for the preservation of wood, leather and paper as well as storage of fruits and vegetables and meat preservation.
8.  2-hydroxy biphenyl is used as the carrier of carrier dyeing method of hydrophobic synthetic fiber polyvinyl chloride and polyester, surfactants, bactericidal preservatives, dye intermediates. In Japan, 2-hydroxy biphenyl and sodium salt is used for the prevention of citrus mildew. We can embed into wax with 0.8% of the product and spray into the post-harvest citrus, or can also use it in combination with biphenyl, being able to minimize the corruption. Britain, the United States, and Canada allow the use of a larger range of fruits, including apples, pears, pineapple and so on. The goods, as a preservative is also used in cosmetics. The oral LD50 of 2-hydroxybiphenyl to rats was 2.7-3.0 g/kg.
9. It can be used for preservation of fruits and vegetables.
10. 2-Phenylphenol can be applied to fluorescence determination of triose. It can also be used as Dye intermediates.
11. Used as a deoxyribonuclease (DNase) inhibitor;

Identification test

Take 1 mL of 1% ethanol solution, plus 4 mL of 0.2% borax solution and a small amount of small crystals of 2,6-dichloro benzoquinone chloride imine, after shaking, the solution should be green to blue.
Take 1 mL of 1% of the sample ethanol solution, plus 1 mL of formaldehyde sulfuric acid solution (TS-113), the interface should be red.

Content analysis

Accurately weigh about 2 g of powder sample, add 25 mL of sodium hydroxide test solution (TS-224), if necessary, it can be warmly dissolved. Add water to 500ml after cooling and take it as a sample solution. Take 25 mL of this sample solution and transfer into the iodine bottle, accurately add 30 mL of 0.1mol/L potassium bromate solution plus 5 mL potassium bromide test solution (TS-181) 5 mL and 50 mL methanol for thoroughly shaking. Quickly add about 10 mL of 1: 1 dilute hydrochloric acid, immediately plug and gently shake for a reaction of 30s. Take 15 ml of potassium iodide solution (TS-192) and place into the upper part of the iodine bottle, and the stopper was let out to let it flow in. After thoroughly rinsing the stopper and bottle with water, the sample was shaken for 5 min. The free iodine was titrated with 0.1 mol/L sodium thiosulfate solution and the starch test solution (TS-235) was used as the indicator. The same method is applied for blank test to obtain content according to the following formula.
Content (%) = 4.255 × (a-b) /sample amount (g) × 50 × 100%
Where a-blank consumption of sodium thiosulfate volume, m1;
B-Sample solution consumption of sodium thiosulfate volume, ml.


ADI: 0 to 0.2 mg/kg (0.2 to 1.0 mg/kg under certain conditions; FAO/WHO, 2001).
LD50: 2.7 to 3.0 g/kg (rat, oral).
The Tokyo health institute in Japan has found that experimental animals have a significant role in bladder cancer.

Usage limit

GB 2760-2001: citrus fresh 1.0g/kg, residues ≤ 12mg/kg.

Production method

(1) It can be recovered from the distillation residue of the process of phenol production via sulfonation. The phenol distillation residue contains about 40% of phenyl phenol with the other components including phenol, inorganic salts, water and so on. After vacuum distillation, the mixed phenyl phenol fraction is separated out with the vacuum being 53.3-66.7kPa. The temperature, started to be cut at 65-75 ℃ to until 100 ℃ above, but should not higher than 1345 ℃. Then take advantage of the solubility difference of ortho, p-hydroxy biphenyl in the trichlorethylene, the two are separated into pure product. The mixed material (mainly 2-hydroxy biphenyl and 4-hydroxy biphenyl) is heated to be dissolved in the trichlorethylene, after cooling, first precipitate out 4-hydroxy biphenyl crystal. After centrifuge filtration, dry to obtain 4-hydroxy biphenyl. The mother liquor was washed with a sodium carbonate solution, followed by dilute alkaline to make the 2-hydroxybiphenyl salt. After standing stratification, take the upper 2-hydroxybiphenyl sodium salt for dehydration under reduced pressure, namely, sodium salt products. The 2-hydroxybiphenylsodium salt is white to light red powder, being easily soluble in water with the solubility in 100g of water being 122g. The pH value of the 2% aqueous solution is 11.1-12.2. It is also easily soluble in acetone, methanol, soluble in glycerol, but insoluble in oil. The sodium salt of 2-hydroxy biphenyl, after acidification, can lead to the formation of 2-hydroxy biphenyl with both of them being food additives.
(2) The mixture of 2-Phenylphenol (o-phenylphenol) and p-phenylphenol is obtained from the by-product of the phenol production by the sulfonation process. The mixture is heated and dissolved in trichlorethylene. After cooling crystallization, we can obtain para-phenylphenol with centrifuge filtering and solid drying to obtain Phenylphenol. The mother liquor was washed with sodium carbonate solution, neutralized with dilute sodium hydroxide and acidified to give o-phenylphenol.
(3) The distillation residue of sulfonation method for production of phenol production contains about 40% of the mixed (para and ortho) phenyl phenol. Taking advantage of difference of the fractionation and solubility in the trichlorethylene, separate and recover ortho products.
The above distillation residue is subject to vacuum distillation at 53.3~66.7 kPa, collecting the distillate fraction at 65~100 °C, namely mixed phenyl phenol. The mixture was heated to be dissolved in trichlorethylene with cooling first precipitating out the para-phenyl phenol. After centrifugal filtration, wash the mother liquor with sodium carbonate solution so that the o-phenyl phenol will become sodium salt. After standing, take the upper sodium salt, after acidification, we can obtain the product.
(4) It can be obtained through the co-heating of dibenzofuran and sodium metal to about 200 °C with the resulting product subjecting to acid decomposition.
(5) It can be obtained through the diazotization and further hydrolysis of 2-aminobiphenyl.

General Description

Light lavender crystals or solid.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

2-Phenylphenol react as a weak organic acid. Exothermically neutralizes bases. May react with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides to generate flammable gas (H2) and the heat of the reaction may ignite the gas. Is sulfonated very readily (for example, by concentrated sulfuric acid at room temperature) in exothermic reactions. May be nitrated very rapidly. Nitrated phenols often explode when heated and also form metal salts that tend toward detonation by rather mild shock. Can react with oxidizing agents .

Fire Hazard

2-Phenylphenol is combustible.
