• 使用

  Fluorescence and phosphorescence quantum yields and fluorescence and phosphorescence lifetimes were obtained for 4-phenylphenol adsorbed on filter paper with either NaCl, NaBr, or NaI at 296 and 93 K. The solid-surface fluorescence and phosphorescence quantum yield values and phosphorescence lifetime values were obtained for p-aminobenzoic acid (PABA) and 4-phenylphenol adsorbed on α-cyclodextrin/NaCl mixtures. 4-Phenylphenol is used as an antioxidant and is a potential EDC.

• 製造方法

  4-phenylphenol synthesis: Add to a 50 ml round-bottom flask, in this order, 122 mg of phenylboronic acid, 414 mg of potassium carbonate, 220 mg of 4-iodophenol, and 10 ml of deionized water. Weigh in a suitably sized container 3 mg Pd on C 10%, add 1 ml of deionized water, and stir gently by hand to form a slurry that is then transferred to the reaction flask.
  
  Couple the flask to a water-jacketed condenser, and reflux the mixture on a hot plate with a magnetic stirrer vigorously for 30 min (until a precipitate appears). After this time, switch off the plate and allow to cool to r.t. Add HCl 2 M to an acidic pH (check with indicator paper). Separate the resulting solid, still containing the catalyst, by filtering with a Hirsch funnel. Wash the solid with 10 ml of water. Then, in a Hirsch funnel, add 10 ml of MeOH, and collect the filtrate in a clean container. Add to the resulting MeOH solution 10 ml of deionized water to obtain the precipitate of the product. Purify by recrystallization, heating in a water bath container with the precipitate and the MeOH/H2O mixture. If necessary, add 1 to 2 ml more of hot MeOH, to finish dissolving the solid. Filter under vacuum with a Hirsch funnel, air dry the solid (can recover the next day). Weigh and calculate the yield.

• 定義

  ChEBI: 4-Phenylphenol is a member of the class of hydroxybiphenyls that is biphenyl carrying a hydroxy group at position 4.

• 一般的な説明

  4-Phenylphenol undergoes enzymatic polymerization and polymer developed is characterized by matrix-assisted laser desorption ionization time-of-flight mass spectrometry. It is the intermediate in manufacture of 4-alkyl substituted phenol-formaldehyde resins.

• 安全性プロファイル

  Acute poison by intraperitonealroute. Questionable carcinogen with experimentalcarcinogenic and tumorigenic data. When heated todecomposition it emits acrid, irritating fumes.

• 純化方法

  Crystallise the phenol from aqueous EtOH, *C6H6, and dry it in a vacuum over CaCl2 [Buchanan et al. J Am Chem Soc 108 7703 1986]. [Beilstein 6 IV 4600.]
