Description of Sodium orthophenyl phenol:
OPP is more selective than other free phenols but does produce phytotoxic effects.

Acetate and butyrate esters gave efficient control of Botrytis on grapes and Monilia on peaches, but esters of o-phenylphenol are easily hydrolyzed into the free phenol. 
The methyl ether was less active against Diplodia and virtually inactive against Penicillia.

Production method
Sodium orthophenyl phenol 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 1345C. 
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. 
Sodium orthophenyl phenol 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.

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.

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.

Sodium orthophenyl phenol can be obtained through the co-heating of dibenzofuran and sodium metal to about 200 °C with the resulting product subjecting to acid decomposition.

Sodium orthophenyl phenol can be obtained through the diazotization and further hydrolysis of 2-aminobiphenyl.

Introduction ortho-Phenylphenol (OPP) and Sodium orthophenyl phenols sodium salt, sodium ortho-phenylphenate (SOPP), are fungicides for the post-harvest-treatments of fruits and vegetables, among other uses (e.g., disinfections and preservatives). 
Scope of the Report:
Ortho-phenylphenol and Sodium orthophenyl phenols water-soluble salt, sodium ortho-phenylphenate (SOPP), are antimicrobial agents used as bacteriostats, fungicides, and sanitizers.
In our data, our data cover 99% solid OPP.
Ortho phenyl phenol (OPP) is widely used in disinfectants industry, material preservation industry and flame retardants industry. 
As to the ortho phenyl phenol (OPP) downstream application, disinfectants industry is Sodium orthophenyl phenols largest downstream market, which shares 60.32% of the consumption in 2015. 
According to the different synthesis process, ortho phenyl phenol (OPP) is divided into chlorobenzene synthesis OPP and cyclohexanone synthesis OPP.

Background: Due to widespread usage, the general public including pregnant women is routinely exposed to the fungicides, Ortho-Phenylphenol (OPP) and Sodium Ortho‑Phenylphenate (SOPP), from many sources. 
Previous data reviews concluded no effects on development or reproduction in animal studies but upon re-analysis we realize that alternative interpretation may exist. 

Sodium ortho-phenylphenate is the sodium salt of ortho-phenylphenol.
Description: The sodium salt of E231, Sodium Orthophenyl Phenol is used as an anti fungal derivative of benzene, used to inhibit the growth of mould on citrus fruits.
Biphenyl is a constituent of the wood preservative creosote. 
This preservative remains on the skins of fruits when they arrive at the retailer.

Degradation
2-Phenylphenol has limited water solubilty but Sodium orthophenyl phenol is very soluble in base, forming the alkali metal salts. 
Sodium orthophenyl phenol is a stable compound but it would be expected to react with oxygen to form quinones as do other phenols. 
The aqueous photolysis of 2-phenylphenol using a high pressure mercury vapour lamp gave phenyl-p-benzoquinone and multi-hydroxylated products. 
Degradation was accelerated by oxygen. 
The rate of degradation was not given in this paper, the main thrust of which was the primary physical steps in the photolysis process.
2-Phenylphenol was completely degraded during 14 days exposure to sunlight in aqueous solution under conditions where is was stable for 56 days in the dark. 
The objective of the study was to demonstrate the photogeneration of mutagens in the presence of nitrate and nitrite. 
Bacterial mutagens, probably nitro compounds, were formed only in the presence of nitrite.

2-Biphenylol is found in lemon. 
Sodium orthophenyl phenol is an antifungal agent and preservative. 
2-Biphenylol is used for post-harvest control of storage disease in apples, citrus fruit, stone fruit, tomatoes, cucumber and peppers through the use of impregnated wrapping materials or by direct application in a wax. 
2-Biphenylol is used in food seasonings. 
Inhibitory to a wider range of moulds than Biphenyl HMJ12-A. 
The practical way of treatment is to immerse citrus fruit in an alkaline aqueous solution of the parent compound or its Na salt

Precautions when using SOPP
 
1)Immersion time should not exceed 3 minutes
2)Fruit picked early in the morning or turgid fruit should be wilted 12-24 hours before immersion in SOPP. 
3)Concentration of SOPP at different temperatures should be determined accurately.
4)Control of pH is very important; too low pH can lead to serious burning of fruit. Too higher temperature, coupled with high concentrations, will burn fruit.
5)Fruit should be rinsed with fresh water after immersion in SOPP.

Characteristic
Food additive E 231 is an organic compound consisting of phenolic hydroxide groups and two benzene rings. 
In appearance Sodium orthophenyl phenol is a white crystalline substance, Sodium orthophenyl phenols melting point is about 57 ° C. 
E 231 is obtained synthetically by heating cyclohexanone to 120 ° C together with acid catalysts, and then, the cyclohexenyl cyclohexanone formed must be subjected to catalytic isomerization of diphenyl ether and catalytic dehydrogenation. 
The orthophenyl phenol E231 resulting from this long process sometimes contains various impurities of biphenyl or biphenyl oxide, or of phenol. 
Sodium orthophenyl phenol belongs to the group of fingocides (substances that fight fungi and their spores) and is a moderately dangerous substance.

Use of Sodium orthophenyl phenol:
The additive E 231 is used in the food industry for processing the outer part of fruits and vegetables, extending their shelf life, protecting them from the harmful effects of fungi and bacteria. 
The additive processes not only fruits (most often citrus), but also the containers in which they are transported over long distances. 
This substance is also used in cosmetics (sprays, deodorants), as a disinfectant in public places and institutions, for seed treatment in agriculture, as a reagent in the chemical industry.
