An important goal is to be able to produce a carbon material with well-defined properties from a given carbonaceous precursor. Based on carbonization mechanisms, some concepts concerning the control of anisotropic development from a given starting material can be developed. There are two principal approaches ... [Pg.40]

The mechanism for formation of the hydrazone is the same as the mechanism for imine formation (Key Mechanism 18-5 in Section 18-15). The actual reduction step involves two tautomeric proton transfers from nitrogen to carbon (Mechanism 18-7). In this strongly basic solution, we expect a proton transfer from N to C to occur by loss of a proton from nitrogen, followed by reprotonation on carbon. A second deprotonation sets up the intermediate for loss of nitrogen to form a carbanion. This carbanion is quickly reprotonated to give the product. [Pg.864]

The system operating pressure is contained by a double-row cooled and lubricated carbon mechanical seal between the casing and rotating shaft in the vapor space at the upper end of the centrifuge assembly. [Pg.251]

Another solution is the use of noble metals. The whisker carbon mechanism does not work because these metals do not dissolve carbon. This is illustrated in Fig. 6 showing results (6) from TGA-tests with a ruthenium catalyst. [Pg.89]

Within the framework of the pentacoordinated carbon mechanism [37g], the unusual stereoselectivity of the hydroxylation of the isotopically substituted camphor in a system with cytochrome P450ca has received natural interpretation... [Pg.485]

Analysis of the results described here as well as those published in the literature for monooxygenases and their chemical analogues shows that, besides the traditional radical mechanism of C-H hydroxylation in the presence of metal complexes, another, five-coordinate, carbon mechanism exists which involves addition of an oxygen atom to a C-H bond, followed by insertion into the C-H bond to form an alcohol. However, the exact nature of the latter mechanism remains to be elucidated and may be somewhat different for different systems. [Pg.487]

Optical microscopy, using polarized reflected light, has been recognized as a very useful tool and has played a major role in studies of carbonization mechanisms and coke quality properties. Examination of a coke polished surface under a microscope reveals the presence of certain parts without optical activity (isotropic coke) and others with optical activity (anisotropic coke). The anisotropic carbon exhibits yellow, blue, and purple areas of various sizes, <1-200 )tm, and shapes (optical texture) with an interchange of color on rotation of the specimen. [Pg.770]

Carbonization Mechanism. The carbonization mechanism of polyaromatic hydrocarbons (PAH) includes the following steps i i... [Pg.77]

As a rule, polymers have a lower carbon yield than aromatic hydrocarbons since they contain, in addition to hydrogen and carbon, other elemente with higher molecular weight, such as chlorine, oxygen, or nitrogen. These elements must be removed. The carbonization mechanism of polymers is usually more intricate than that of aromatic hydrocarbons since the composition is more complex. The carbon yield is unpredictable in many cases.l i... [Pg.78]

The exact carbonization mechanism is still conjer ral but appears to be related to the degree of cross-linking of the precursor polymer. A proposed mechanism for the carbonization of polyfurfuryl alcohol is shown in Fig. 6.1 The volatile compounds, H2, CO, COj, CH2, and H2O, slowly diffuse out and, when 1300°C is reached, the material is essentially all carbon. [Pg.125]

Dehydration occurs according to a carbonation mechanism. As a result of this electrophilic detachment of water, when the oxygen atom forms protonized unshared electron pairs, the formation of the carbonic ion is the most important stage of the mechanism ... [Pg.75]

However, the carbonate mechanism is favored by some authors. Using a combination of DRIFTS and steady-state isotopic transient kinetic analysis (SSITKA) Meunier et al. assessed the reactivity of the species formed at the surface of an Au/Ce(La)02 catalyst during the WGS reaction. The analysis revealed that surface formates are not important factors in the WGS reaction mechanism. Their role is ascribed to minor reaction intermediates but not spectators because they nevertheless participate in the formation of reaction product. [Pg.548]
