Adsorption of phenol and chlorophenols on pure and modified sepiolite [PDF]

open access: yesJournal of the Serbian Chemical Society, 2007
In this work, pure sepiolite and sepiolite modified by nitric acid (HNO3), ethylenediaminetetraacetic acid (EDTA) and hexadecyltrimethylammonium (HDTMA) were used ad adsorbents. The changes on the surface were studied by IR spectroscopy.

Insight into Solvent Coordination of an Iron Porphyrin Hydroxylamine Complex from Spectroscopy and DFT Calculations [PDF]

open access: yes, 2018
The reduction of Fe(OEP)(NO) in the presence of substituted phenols leads to a three‐electron reduction to form Fe(OEP)(NH2OH), which has been characterized by visible spectroscopy and electron stoichiometry.

Nature et origine des odeurs de « moisi » dans les caves. Incidences sur la contamination des vins

open access: yesOENO One, 1994
Les goûts et odeurs à caractère "moisI" retrouvés dans les vins encore stockés en cuves ou en barriques sont généralement dus à des chloroanisoles du type 2,3,4,6-tétrachloroanisoleet pentachloroanisole.
