Product Applications

It is used for preservation and preservation of fruits and vegetables; As antiseptic, it is stipulated in our country that it can be used for preservation of citrus. The maximum usage is 3.0 g/kg, and the residual amount is not more than 12 mg/kg.; As an antiseptic, our country stipulates that it can also be used for citrus preservation, with a maximum usage of 3.0 g/kg and a residual amount of no more than 1..

Production method

It can be recovered from the distillation residue of phenol produced by sulfonation. The distillation residue of phenol contains about 40 phenyl phenol, and other components are phenol, inorganic salt, water, etc. After vacuum distillation, the mixed phenyl phenol fraction is separated, the vacuum degree is 53.3-66.7kPa, and the temperature is 65-75 ℃, starting to intercept to above 100℃, but not exceeding ℃. The solubility difference of O-hydroxybiphenyl and para-hydroxybiphenyl in Trichloroethylene is used to separate them into pure substances. The mixture (mainly 2-hydroxybiphenyl and 4-hydroxybiphenyl) is heated and dissolved in trichloroethylene. After cooling, 4-hydroxybiphenyl is first separated and crystallized, and then filtered by centrifugal filtration; dry to 4-hydroxybiphenyl. Wash the mother liquor with sodium carbonate solution, and add dilute alkali solution to salt 2-hydroxybiphenyl. After standing and layering, take the upper layer of 2-hydroxybiphenyl sodium salt and dehydrate under reduced pressure to obtain the finished product of sodium salt. 2-hydroxybiphenyl sodium salt is white to light red powder. It is easily soluble in water, 122g soluble in 100g water, and the pH of 2 aqueous solution is 11.1-12.2. Also soluble in acetone; Methanol, soluble in glycerol, but insoluble in grease. 2-hydroxybiphenyl sodium salt can be acidified to produce 2-hydroxybiphenyl, both of which are food additives.
