With appropriate choices of kinetic constants, this approach can reproduce the NSC experimental data quite well. Park and Appleton [63] oxidized carbon black particles in a series of shock tube experiments and found a similar dependence of oxidation rate on oxygen concentration and temperature as NSC. Of course, the proper kinetic approach for soot oxidation by 02 undoubtedly should involve a complex surface reaction mechanism with distinct adsorption and desorption steps, in addition to site rearrangements, as suggested previously for char surface combustion. 

Similar waves in the cathodic polarogram were observed by Donnet and Henrich 58) using oxidized carbon black. The wave disappeared after treatment with isobutyronitrile. It was assumed that isobutyro-nitrile gives an addition reaction with quinones. No reaction with this reagent was observed after reduction with hydrogen iodide, after treatment with aniline, or after treatment with diazomethane. The latter finding confirms the assumption by Studebaker et al. 38) that diazomethane is added to the quinones in the carbon black surface. 

Since the number of free radicals calculated from the dilference in nitrogen uptake (1.13 102 /gm) agreed well with the number of unpaired electrons as determined by e.s.r. (0.80-10 /gm), the aroxylic structure seemed very likely. The reaction of oxidized carbon black with styrene can be explained on this basis 102). 

It appears from the evolution of the adhesion index that a distinction has to be made between the interactions carbon blacks are able to have with unsaturated or with saturated (or near-to-saturated) elastomers. Thus, the adhesion index of butyl rubber is enhanced upon oxidation of the black, while the reverse is observed with polybutadiene 38). The improvement of the reinforcing ability of carbon black upon oxidation, in the former case, has been interpreted by Gessler 401 as due to chemical interactions of butyl rubber with active functional groups on the solid surface. Gessler, relating the reinforcing characteristics of the oxidized carbon black for butyl rubber to the presence of carboxyl groups on the surface of the filler, postulated a cationic... 

Oxidized carbon blacks may contain up to 15 wt% oxygen. They are strongly hydrophilic. Some of them form colloidal solutions spontaneously in water. In polar printing ink systems, lacquers, and coatings, a better wettability and dispersibility is achieved through surface oxidation [4.26], thus reducing binder consumption.

Figure 27. FT-1R data of heavily oxidized carbon blacks. The FLA sample is much more graphitic in the stacking order of the BSU and exhibits only 10% of the geometric surface area of the standard FW-1 sample.

Some pigments (zinc oxide, carbon black) are also reinforcing agents, butthe two terms are not synonymous in the parlance of the paint and rubber industries these distinctions are not always observed. Pigments may be classified as follows ... 

For van der Waals interaction, o. =2.5 and P = 14.1. For the system containing carboxylated acrylonitrile rubber and ISAF carbon black, a = 4 and P = 42. If ISAF carbon black is oxidized, a remains the same and P increases to 53 which is consistent with the fact that oxidized carbon black has more reactive sites and therefore molecular interaction should increase." When the system is vulcanized, P further increases to 62 for ISAF carbon black and to 68 for oxidized carbon black, meaning that additional interactions occur. Additional mixing also increases the value of a. This is what mixing is intended to do. Because mixing increases the...
