Carbon characteristic data

Proton and Carbon NMR Data. Some characteristic 13C and XH NMR data for fluorinated allylic alcohols and bromide are provided in Scheme 3.44. 

Fortimately, several hydrocarbon liquids which are of interest in the present discussion have been among those studied. Turnbull and Cormia [66] report a value of 9.6 dynes per cm. for the solid-liquid interfacial tension of n-octadecane and 7.2 dynes per cm. for n-hepta-decane. They suggest that these two values are characteristic of the higher n-alkanes with even and odd numbers of carbon atoms, respectively. That is, for each series, the solid-liquid tension is independent of the number of carbon atoms. Data for other hydrocarbons are given by Thomas and Stavely [64]. They report values of 20.4 dynes per cm. for benzene, 24.0 for biphenyl, and 30.1 for naphthalene. 

Stable carbon isotopes data—As shown in Table 2 and Fig. 3, the extracted sediment residue exhibits value (—24.24%o) which is lower than the SMB sediment (—22.41%o) and Southern Ocean site in the South Pacific sector in the Antarctic Circumpolar Current region (Wang and Druffel, 2001) but falls within the range of values, —23.90 to —26.50%o, obtained from the unextracted sediments earlier from the same region (Venkatesan, 1988) and from the Ross Ice Shelf (Sackett, 1986). The lower values are characteristic of mixed inputs from the cold water plankton, especially the diatom-ooze and older recycled kerogen from the shale fragments (Sackett, 1986). With the exception of ketone and aliphatic fractions, all other lipid fractions have a lower value in the... 

In the furnace process, which today dominates carbon black production, oils rich in aromatics from naphtha or gas oil pyrolysis, cat-cracker residues (decant oils) together with mixtures of aromatics from coal tar, are used as feedstock. Table 13.5 summarizes the characteristic data for decant oil, pyrolysis oil from naphtha cracking and a carbon black feedstock derived from coal tar.

Characteristic data of different catalysts, including the sorption capacities for both oxygen and carbon monoxide, and the rates determined in the second regime at 60 °C and an oxygen concentration of 6 vol.%, are resumed in table 2. In the case of the tin(IV)onde containing catalysts (cat. 1 to cat. 3) both the platinum content and the carbon monoxide sorption capacity related to the catalyst mass vary slightly. However, since carbon... 

Gilson et al. [12] studied technique to simultaneously reduce both the hydrogen sulfide and siloxanes concentration to less than 1 ppm. Five different commercial activated carbons (AC) previously studied [77] and effective in H2S removal have been tested at L2 at concentration of 100-200 ppm. Samples differ in specific surface area. Their performances are compared to understand which mechanism controls siloxane removal and which carbon characteristic plays a role in the adsorption process. Table 7.5 summarizes data of the tested ACs.
