Improving synthetic hindered phenol antioxidants: learning from vitamin E
The eciency of various commercial hindered phenol antioxidants was studied using dierential scanning calorimetry (DSC) to determine the oxidation induction time (OIT) of antioxidant solutions in squalane. It was observed that a-tocopherol has an exceptionally high antioxidant activity. In fact, after normalisation for the molecular weight and functionality of each antioxidant, a-tocopherol wa...
متن کاملEvaluation of removal efficiency of phenol from synthetic aqueous solutions by Citrullus colocynthis seed ash
Background: Phenol is a prevalent pollutant found in many industrial wastewaters, and it is paid singular attention because of its special features like high toxicity, carcinogenic properties, and vital gathering ability that affects the health of humans and the environment. One of the most important technologies for the removal of phenol is the use of adsorbents. The current study investigate...
متن کاملRemoval of Phenol from Synthetic and Industrial Wastewater by Potato Pulp Peroxidases
Plant peroxidases have strong potential utility for decontamination of phenol-polluted wastewater. However, large-scale use of these enzymes for phenol depollution requires a source of cheap, abundant, and easily accessible peroxidase-containing material. In this study, we show that potato pulp, a waste product of the starch industry, contains large amounts of active peroxidases. We demonstrate...
متن کاملOrgano-Iodine(III)-Catalyzed Oxidative Phenol-Arene and Phenol-Phenol Cross-Coupling Reaction.
The direct oxidative coupling reaction has been an attractive tool for environmentally benign chemistry. Reported herein is that the hypervalent iodine catalyzed oxidative metal-free cross-coupling reaction of phenols can be achieved using Oxone as a terminal oxidant in 1,1,1,3,3,3-hexafluoropropan-2-ol (HFIP). This method features a high efficiency and regioselectivity, as well as functional-g...
متن کامل2-(4-Hydroxyphenylsulfonyl)phenol
The title compound, C(12)H(10)O(4)S, is a phenolic color developer used for leuco colorants. The two benzene rings with substituent hydr-oxy groups are nearly perpendicular to each other [dihedral angle = 91.5 (1)°]. There are inter-molecular O-H⋯O hydrogen bonds between an OH group of one mol-ecule and a sulfonyl O atom of a neighboring mol-ecule. One mol-ecule is hydrogen bonded to four symme...
