The metabolism of phenol and substituted phenols in zebra fish
Xenobiotica, 19871. The metabolism of five phenols in zebra fish was studied after uptake from the medium. The results showed no qualitative differences to other Cyprinid fish species, only the oxidation rate seemed to be lower. 2. Phenyl glucuronide, phenyl sulphate, and quinol sulphate were identified as metabolites of phenol. 3.

Electropolymerization Treatment of Phenol Wastewater and the Reclamation of Phenol
Water Environment Research, 2012Abstract Electrochemical treatment of phenol wastewater was carried out with stainless steel anodes, and phenol removal was achieved through the electropolymerization process. The effects of phenol concentration and bath voltage were discussed. The original chemical oxygen demand (COD) value was approximately 500 mg/L.

Efficiency of Trapping Methylglyoxal by Phenols and Phenolic Acids
Journal of Food Science, 2011Abstract: The carbonyl stress that leads to the formation of advanced glycation end products (AGEs) has drawn much attention recently because of its micro‐ and macrovascular implications. During monitoring of methylglyoxal (MG), the efficiency of phenolics to directly trap MG can be demonstrated.

Simple phenol and phenolic compounds in food flavor
C R C Critical Reviews in Food Science and Nutrition, 1978Simple phenol and phenolic compounds occur in a vast portion of our diet. This review attempts to discuss their occurrences relative to our food supply. In addition, their chemical, nutritional, and sensory properties are explored, as well as methods for their isolation, identification, and quantitation.

Adsorption of phenol and substituted phenols by iron oxides
Environmental Toxicology and Chemistry, 1991Abstract The ability of Fe oxides to adsorb phenol and various substituted phenols from dilute aqueous solution and from the vapor state was investigated, utilizing Fourier transform infrared (FTIR) spectroscopy to evaluate the type of surface complex formed.

Abstract: Wine contains many phenolic substances, most of which originate in the grape berry. The phenolics have a number of important functions in wine, affecting the tastes of bitterness and astringency, especially in red wine. Second, the color of red wine is caused by phenolics.

Kinetics of Ozonation of Phenol and Substituted Phenols
Industrial & Engineering Chemistry Research, 2019In the treatment of wastewaters contaminated with phenol and substituted phenols, an intermediate chemical step of partial oxidation is often employed to facilitate the ensuing biodegradation process. Ozonation is a candidate technique for partial oxidation of phenolics.

Catalytic ethoxylation of phenol and phenol derivatives
Reaction Kinetics and Catalysis Letters, 1980The kinetics of catalytic mono- and polyethoxylation of phenol, p-cumyl-phenol and p-isooctylphenol have been studied in the presence of strongly basic anion exchanger Wofatit SBW in hydroxy form. The influence of substituents on the rate has been investigated and the mechanism of the reaction is discussed.

Abstract Two alkali metal phenolate/phenol complexes are reported. The cations are pseudo-octahedrally coordinated by oxygen atoms and the π-systems of phenolates and solvent phenols. The ratio of phenolate/phenol determines whether the oxygen atom of the phenolate participates in the coordination of the metal.

Photocatalytic Degradation of Phenol
Environmental Monitoring and Assessment, 2003In this study photocatalytic degradation of phenol in the presence of UV irradiated TiO2 catalyst and H2O2 was investigated. Effects of TiO2 and H2O2 concentrations and pH on photocatalytic degradation were examined. The rate constants for photocatalytic degradation were evaluated as a function of TiO2 and H2O2 concentrations and pH of the solution. It
