abstract   background: phenol and its compounds are common environmental contaminants, which because of their potential harm to human health, are considered as priority pollutants. in this study, the potential of ostrich feather for phenol removing from aqueous solution was studied. methods: removing the phenol from the aqueous solution was studied via considering the effect of absorbent (0.1, ...

background: phenol and its derivatives like dinitrophenol and pentachlorophenol (carbolic acid) are widely used as insecticides, but they are very toxic substances. phenol is a general protoplasmic poison with corrosive local effects that denature proteins. poisoning with phenol compounds may occur by ingestion, inhalation, and absorption through skin. in this report we presented the toxicity e...

Soaps have been extensively used, often with added alkali, to emulsify or make soluble phenolic compounds of limited solubility (Klarmann, Shternov and Von Wowern, 1929; McCulloch, 1936). There is, however, a good deal of controversial information in the literature dealing with the effect of soaps on the germicidal action of phenolic compounds. Frobisher (1927) reported that small amounts of so...

The second-order rate constants for the microbial transformation of a series of phenols were correlated with the physicochemical properties of the phenols. The compounds studied were phenol, p-methylphenol, p-chlorophenol, p-bromophenol, p-cyanophenol, p-nitrophenol, p-acetylphenol, and p-methoxyphenol. Phenol-grown cells of Pseudomonas putida U transformed these compounds. Microbial transforma...

Palladium-catalyzed oxidative annulations between phenols and alkenylcarboxylic acids produced a library of benzofuran compounds. Depending on the nature of the substitution of the phenol precursor, either 2,3-dialkylbenzofurans or 2-alkyl-3-methylene-2,3-dihydrobenzofurans can be synthesized with excellent regioselectivity. Reactions between conjugated 5-phenylpenta-2,4-dienoic acids and pheno...

In this work, the volatile profiles of smoked and non-smoked Iranian rice were identified, and their relative abundance was calculated and compared. Headspace solid-phase microextraction together with gas chromatography-mass spectrometry (SPME-GC-MS) were used to extract and identify the volatile compounds. The main groups of volatiles in Iranian rice were aldehydes, ketones, phenol derivatives...

Bajakah kalalawit is one of the plants that has been empirically used in traditional medicine. The roots (Uncaria gambir Roxb) have phenol and antibacterial content a high enough flavonoid compounds so they pharmacological activity as an anticancer. This article examines contained extract Kalalawi root also total levels flavonoids Kalalawi. was obtained by infundation extraction method using wa...

This study was designed to identify and quantify the major phenolic constituents in peeled kernel pellicle of walnut Juglans regia L. Data were compared across six different cultivars: 'Fernor', 'Fernette', 'Franquette', 'Sava', 'Krka' 'Rubina'. High-performance liquid chromatography coupled with mass spectrometry used these compounds. Nineteen ellagitanins, 12 ellagic acid derivatives, 4 antho...

a series of 2-amino-4-aryl-3-cyano-7-(dimethylamino)-4 h -chromenes was synthesized by condensation of 3-(dimethylamino)phenol, an aromatic aldehyde and malonitrile in ethanol containing piperidine. the assignments of the structure of all synthesized compounds were based on spectral data (ir, mass and 1 h nmr). the cytotoxic activities of the synthesized compounds against six human tumor cell l...
