Sonochemical degradation of phenol (Ph), 4-isopropylphenol (4-IPP) and Rhodamine B (RhB) in aqueous solutions was investigated for a large range of initial concentrations in order to analyze the reaction kinetics. The initial rates of substrate degradation and H(2)O(2) formation as
The pyrolysis of bisphenol A (BPA), an essential process ingredient used in industry and many everyday life products, helps produce low-industrial-demand chemicals such as isopropenyl- and isopropyl-phenols (IPP and iPrP). In this study, tandem micro-reactor gas chromatography/mass spectrometry combined with
Sphingobium xenophagum Bayram is capable of metabolizing 4-alkoxyphenols and endocrine disruptive alpha-quaternary 4-nonylphenols by an ipso-substitution mechanism that involves ring hydroxylation at the site of the substituent. Here, we show that Bayram's ipso-hydroxylating activity was able to transform also bisphenol

The oxidative metabolism and toxicity of the para isomers of methylphenol (cresol), ethylphenol, and isopropylphenol were studied using male Sprague-Dawley rat liver microsomes and precision-cut liver slices. Reactive intermediates from each compound were trapped using radiolabeled glutathione and were detected
Applied and environmental microbiology, 69(6), 3650-3652 (2003-06-06)
4-ethylphenol methylenehydroxylase from Pseudomonas putida JD1 acts by dehydrogenation of its substrate to give a quinone methide, which is then hydrated to an alcohol. It was shown to be active with a range of 4-alkylphenols as substrates. 4-n-propylphenol, 4-n-butylphenol, chavicol
