In real systems (hydrocarbon-02-catalyst), various oxidation products, such as alcohols, aldehydes, ketones, bifunctional compounds, are formed in the course of oxidation. Many of them readily react with ion-oxidants in oxidative reactions. Therefore, radicals are generated via several routes in the developed oxidative process, and the ratio of rates of these processes changes with the development of the process [5], The products of hydrocarbon oxidation interact with the catalyst and change the ligand sphere around the transition metal ion. This phenomenon was studied for the decomposition of sec-decyl hydroperoxide to free radicals catalyzed by cupric stearate in the presence of alcohol, ketone, and carbon acid [70-74], The addition of all these compounds was found to lower the effective rate constant of catalytic hydroperoxide decomposition. The experimental data are in agreement with the following scheme of the parallel equilibrium reactions with the formation of Cu-hydroperoxide complexes with a lower activity.

Vanadium oxide dispersed on supporting oxides (Si02 Al Oo, Ti02, etc.) are frequently employed as catalysts in reactions like partial oxidation and ammoxidation of hydrocarbons, and NO reduction. The modifications induced on the reactive properties of transition metal oxides like V20 when they are supported on an oxide carrier has been the subject matter of recent study. There is much evidence showing that the properties of a thin layer of a transition metal oxide interacting with the support are strongly modified as compared to the properties of the bulk oxide (1-3). In the recent past, increasing attention has been focussed... 

There are two major routes of formation of an unstable metal-ligand system (a) The metal ion in its given state of oxidation interacts with the ligand to give an unstable system (via Mechanisms 1 or 2). (b) The metal-ligand system is stable...

Some of the above products of decompn (ammonia and nitrogen oxides) interacted with the evoln of heat. This heat might raise the temp of the gases above the molten AN to such an extent that they could explode and cause the explosn of the molten AN in the tube. In order to avoid the danger of expln...

Europium oxide interacts with stainless steel (grain boundary attack) above 500°C, to form europium silicate. No interaction occurs even at 1230°C when the silicon content of the steel is less than 58 ppm. Molybdenum or tungsten could be used as protective barriers, since these metals do not react with EU2O3 at elevated temperatures. ... 

In many cases photophysical effects are much influenced by photochemical reaction. The fluorescence of naphthacene is affected by dimerization and oxidation. Interaction with anthracene and quinones also occurs. The adiabatic photolytic cycloreversion of substituted lipidopterenes into intramolecular exciplexes shows an example involving anthracene derivatives. A series of very detailed papers on conformational effects on the fluorescence and photochemistry of [2/j] 9,10-anthracenophanes have been published by Ferguson and coworkers.It is not possible in this review to summarize this very detailed work... 

Since the successful use of phenylphosphiiK dichloride 2 [11], hexachloro-cyclotriphosphatriazene 3 [12], triphenylphosphine 4 [13] and diphenylchloro-phosphate 5 [14] in the synthesis of polyesters, Ogata et al. studied direct polycondensation of diacid and diamii in the presence of triphenylphosphine dicMoride (TPPCI2) [15b] which can form in situ when triphenylphosphine is treated with hexachloroethane or when triphenylphosphine oxide interacts with phosgene or oxalyl chloride (Scheme 3) [15a],...

No changes in the phase composition of the samples were found by XRD after the treatment at 350°C. WC, Ni, and traces of WO3 were found after hydro-thermal treatments in the temperature range 400-500°C. WO3 dissolves in water and a weight loss of the samples was observed. At 700°C, oxidation of Ni occurs and nickel oxide interacts with WO3 (or H2WO4) leading to the formation of NiW04.
