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 Ortho-Phenylphenol (OPP) 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.
Ortho-Phenylphenol (OPP) is also easily soluble in acetone, methanol, soluble in glycerol, but insoluble in oil.
The sodium salt of Ortho-Phenylphenol (OPP), after acidification, can lead to the formation of Ortho-Phenylphenol (OPP) with both of them being food additives.
