Data for oxidation

Foohiotes (a) Data from [9], adjusted to see using data for oxidation of 2,2,6,6-tetramethylpiperidinyl-1 -oxyl. 

Shidlovskiy has gathered data on burning rates for some of the common oxidizers [1]. Table 5.5 contains data for oxidizers with a variety of fuels. Again, note the high reactivity of potassium chlorate.

At higher temperatures the C2 hydrocarbons (ethane, ethylene, acetylene) are oxidized along the same pathways as outlined in Section 14.3.1. The C2 radicals C2H5 and C2H3 are much more reactive than CH3, and consequently C2 hydrocarbons are more easily oxidized than methane. This is illustrated in Fig. 14.4, which shows data for oxidation of selected hydrocarbons in a flow reactor. Measurements of the outlet CO concentration, obtained in the 800 to 1500 K range under slightly fuel-rich conditions, are compared with modeling predictions [148].

The experimental data for oxidation of benzyl alcohol,1 aliphatic primary and secondary alcohols,2 and cholesterol3 with cetyltrimethylammonium (CTA) dichromate indicated that the reactions occur in a reverse micelle system produced by the oxidant. Michaelis-Menten-type kinetics were observed with respect to the reductants. The product of the oxidation of cholesterol depends on the solvent. In dichloromethane, the product is 7-dehydrocholesterol, whereas with dichloromethane containing acetic acid the product is 5-cholesten-3-one. A low kinetic isotope effect, k /ku = 2.81, was observed in the oxidation of methanol- this, combined with the rate data and the reverse solvent isotope effect [ (H20)/fc(D20) = 0.76], suggests that these reactions... 

Other traditional scales, such as that of Goldschmidt, are more empirically based and rely upon experimental internuclear distances found in oxides and fluorides (which are expected to be particularly ionic) assumed values for the radii of F and O2- are needed. A very complete tabulation, based on a large amount of modern data for oxides and fluorides, both binary and complex, has been published by Shannon and Prewitt using values of 133 pm for F and 140 pm for O2-. One of the merits of this collection is that it recognises the dependence of ionic radii oh the coordination number. For example, in the case of Cd2+ radii are quoted for coordination numbers 4, 5, 6, 7, 8 and 12 as shown below ... 

Thermodynamic data at 298.15 K were mostly taken from Wagman et al.3 High temperature data for the above-mentioned three sulfites were taken from the HSC database referred to in Chapter 1.1. No thermodynamic data for oxides are included, since they were already given in Chapter 2, and sulfates, which may also be decomposition products, are described in Chapter 4. Therefore, when only minimal data are available, they are given in the text rather than in individual tables.

Some data in Table 2.2 refer to amorphous materials. The crystalline phases are well defined, but amorphous materials are not, thus, the thermochemical data can differ from one amorphous sample to another. The data in Table 2.2 illnstrate a typical difference in Gibbs energy between the most stable crystalline phase and amorphous materials. There are other compilations of thermodynamic data, which were not used in Table 2.2. Some additional data for oxides and silicates is available from Ref. [16]. The old units (kcal/mol) were used in that book. A collection of thermodynamic data, chiefly for silicates can be found in Ref. [17].

It should be emphasised that the calculations shown in the two examples above are not considered to reflect exactly the experimental conditions and particle/crystallite size distributions in these studies. However, they point out important problems in the interpretation of solubility data for oxides or oxyhydroxides of tetravalent metal ions ... 

The most thoroughly studied class of phenoxyl radical complexes was prepared by oxidation of first-row transition metal complexes of the type of macrocyclic phenolate ligands shown in Figure 4. Studies of those compounds that contain Ga , Sc , and have been particularly useful for differentiating and establishing the properties of coordinated vs. uncoordinated phenoxyl radicals. Due to their closed shell nature, these ions are both spectroscopically silent and redox inactive, thus enabling the properties of phenoxyl radicals in their complexes to be seen unmasked from those of the metal ion. Data for oxidized forms of the complexes [L M] ((l)-(4) are illustrative). These compounds undergo three reversible one-electron oxidations at approximately equally spaced...
