Using Physical Organic Chemistry Knowledge to Predict Unusual Metabolites of Synthetic Phenolic Antioxidants by Cytochrome P450 | Chemical

Biotransformation, especially by human CYP450 enzymes, plays a crucial role in regulating the toxicity of organic compounds in organisms, but is poorly understood for most emerging pollutants, as their numerous ¡°unusual¡± biotransformation reactions cannot retrieve examples from the textbooks. Therefore, in order to predict the unknown metabolites with altering toxicological profiles, there

Novel High Molecular Weight Synthetic Phenolic Antioxidants in Indoor Dust in Toronto, Canada | Environmental Science … – ACS Publications

Synthetic phenolic antioxidants (SPAs) are additives that are used to retard oxidative degradation in polymers, extending their lifespans. Previous studies have mainly focused on the pollution and toxicity risk of low molecular weight SPAs such as 2,6-di-tert-butyl-4-methylphenol (BHT, C15H24O). In this study, 10 novel high molecular weight SPAs were investigated, along with BHT. Surprisingly

Hindered phenolic antioxidants as heat-oxygen stabilizers for HDPE – SAGE Journals

To get further insight on the heat-oxygen stability of HDPE with hindered phenolic antioxidants, the OIT values of pure HDPE and HDPE in combination with antioxidants were measured, as shown in Figure 4. The OIT value of pure HDPE is 54.12 min, during hindered phenolic antioxidants are introduced, and the OIT values increase in various degrees.

Rubber Antioxidants and Their Transformation Products: Environmental Occurrence and Potential Impact

Natural antioxidants are only found in NR, such as amino acids, tocotrienol, and betaines [], whereas physical and chemical antioxidants are widely used in various synthetic rubber products. The rubber-aging process comprises three stages: initiation, reaction, and termination [ 15 , 16 ], and the physical antioxidants are usually used to address the initiation stage of rubber aging.

Recent progress in the rubber antioxidants: A review

This review mainly focused on thermo-oxidative aging because it is the most common aging type for rubbers. The oxidative degradation of rubber proceeds by a free-radical chain reaction mechanism [1]. As shown in Fig. 1a, rubber aging processes have three distinct phases: (i) Initiation, (ii) Propagation, and.
