“…The aerobic oxidation of hydrocarbons is a very important commercial process for the production of oxygen‐containing compounds such as alcohols, aldehydes, ketones, carboxylic acids, and epoxides 1–4. However, the reaction conditions are often harsh, the reagent mixtures are corrosive (Cl − or Br − ), and the reactions are frequently unselective.…”

In this work, we study cyclohexene oxidation by molecular oxygen on doped-TiO 2 . The improvement of the oxidizing capacity of titanium oxide by doping with iron oxide at different molar ratios is checked. All materials with different molar ratios (Ti/Fe = 9, 4, and 2) are prepared by the sol-gel method and fully characterized by ICP, XRD, SEM, DR/UV-vis, IR, and N 2 adsorption/desorption. The results show that iron is successfully incorporated into the titanium matrix but the incorporated amount is limited. In catalytic tests, improved activity is noticed while using TiO 2 in the presence of Fe 2 O 3 , which is due the improved oxidation. Conversion in the range of 21-42% depending on the presence of iron oxide was obtained with excellent yield of adipic acid (97% selectivity).

“…Scott [2] proposed a mechanism involving [/P -OH ::: OR]. However, due to the fact that there are similar electron densities on both the oxygen atoms in the hydroperoxides [3], there is also the possibility that an equivalent amount of [/P -OR ::: OH] could also form. In fact, this radical mechanism leads to efficient stabilization only if the radicals do not escape from the cage.…”

Modelling of thermal oxidation of phosphite stabilized polyethylene. Polymer Degradation and Stability, Elsevier, 2011, 96 (7), pp. a b s t r a c tThe thermal oxidation behaviour of polyethylene films stabilized by various weight ratios of organophosphites (Irgafos 168) has been studied at selected temperatures. The duration of the induction period was found to increase proportionally with the stabilizer concentration, even at temperatures as low as 80 C. Particular attention was paid to the phosphiteephosphate conversion during the induction period. A kinetic model, involving volatile and partially soluble hydroperoxide decomposers, was developed in order to simulate these results. With the use of kinetic parameters that can be at least tentatively justified from theoretical considerations, this model gave simulations in reasonable agreement with the experimental observations for stabilizer depletion and carbonyl formation. Of particular note is the fact that, even for non-trivial results such as the shape of the phosphite versus phosphate concentration plots, or phosphate build-up, there was also a quite good agreement.
