Oxidation of Drugs during Drug Product Development: Problems and Solutions
Pharmaceutics, 2022 Oxidation is the second most common degradation pathway for pharmaceuticals, after hydrolysis. However, in contrast to hydrolysis, oxidation is mechanistically more complex and produces a wider range of degradation products; oxidation is thus harder to ...

Synthesis and characterization of polymeric linseed oil grafted methyl methacrylate or styrene [PDF]
, 2004 Syntheses of wholly natural polymeric linseed oil (PLO) containing peroxide groups have been reported. Peroxidation, epoxidation and/or perepoxidation reactions of linseed oil, either under air or under oxygen flow at room temperature, resulted in ...

The Thermal degradation of Bisphenol A Polycarbonate in Air [PDF]
, 2005 The thermal degradation of polycarbonate in air was studied as a function of mass loss using TGA/FTIR, GC/MS and LC/MS. In the main degradation region, 480–560 °C, the assigned structures of smaller molecules and linear molecules that evolved in air were

The decomposition of alkyl peroxides: dipropyl peroxide, ethyl hydrogen peroxide and propyl hydrogen peroxide [PDF]
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1939 In a previous paper (Harris and Egerton 1938) the results of an investigation of the decomposition of diethyl peroxide have been published. The present communication deals with the related compounds ( a ) dipropyl peroxide, which closely resembles the diethyl compound as it decomposes unimolecularly, ( b

Characterization of different ozonized sunflower oils I. Chemical changes during ozonization
Grasas y Aceites, 2019 Vegetable oils are usually rich in unsaturated fatty acids which are susceptible to oxidation. The oxidation of vegetable oils has been one of the most widely studied fields within lipid chemistry, because it alters their properties and nutritive value ...

Dimethylenediol peroxide (diformal peroxide hydrate) [PDF]
Proceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1914 The conditions of the co-existence of hydrogen dioxide and formaldehyde, and the nature of their interaction, are of special interest in connection with the theories which have been advanced to account for the photosynthesis of carbohydrates in plants.
