-Agricultural Uses of o-phenyl phenol:
Fungicide, Disinfectant, Microbiocide:
o-phenyl phenol is used to make fungicides.
o-phenyl phenol is also used to make dye stuffs and rubber chemicals, but used primarily as a disinfectant cleaner.

PRODUCTION METHODS of O-PHENYL PHENOL:
OPP is produced as a by-product in the manufacture of diphenyl oxide or by aldol condensation of hexazinone.

PREPARATION METHOD of O-PHENYL PHENOL:
using cyclohexanone route to prepare o-phenyl phenol, namely, using cyclohexanone as raw material, condensation dehydration under acid catalysis to obtain the dimerization Intermediate 2-(1-cyclohexenyl) cyclohexanone and 2-ring hexylene cyclohexanone, O-Phenylphenol was synthesized by dehydrogenation.
a mixture of o-phenyl phenol and p-Phenylphenol is obtained from the by-product of phenol production by sulfonation method.

The mixture is heated and dissolved in trichloroethylene, and the crystals of p-Phenylphenol are precipitated by cooling, and then centrifuged and filtered, the solid was dried to give P-Phenylphenol.
The mother liquor was washed with sodium carbonate solution, neutralized with dilute sodium hydroxide and acidified to obtain o-phenyl phenol.

CHEMICAL PROPERTIES of O-PHENYL PHENOL:
o-phenyl phenol is a white to buff-colored crystalline solid with a distinct odor.
When heated to decomposition, o-phenyl phenol emits acrid smoke and irritating fumes.

FUNCTIONS (INCI) of O-PHENYL PHENOL:
*Preservative:
o-phenyl phenol inhibits the development of microorganisms in cosmetic products.

FUNCTION(S) of O-PHENYL PHENOL IN COSMETIC PRODUCTS:
*PRESERVATIVE
o-phenyl phenol protects cosmetic products from microbial spoilage.

PREPARATION of O-PHENYL PHENOL:
o-phenyl phenol can be recovered from the distillation residue of the process of phenol production via sulfonation.
o-phenyl 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.

o-phenyl phenol is sulfonated very readily (for example, by concentrated sulfuric acid at room temperature) in exothermic reactions.
o-phenyl phenol may be nitrated very rapidly.

Nitrated phenols often explode when heated and also form metal salts that tend toward detonation by rather mild shock.
