Alkanes aromatization

As shown in Table 8, the spray paint solvent is predominately a mixture of several linear aliphatic, branched aliphatic, and cycloaliphatic hydrocarbons, and toluene, xylenes, and ethyl benzene. 2-Butanone (also known as methyl ethyl ketone) was also detected. The breakdown of the solvent mixture by class of compound (aromatic, //-alkane, iso-alkane, cyclic alkane, and others) is shown in Table 9. The solvent appears to be consistent with a mixture of a VM P naphtha... 

Benzene can also be produced from petroleum hydrocarbons by aromatization. Alkanes can be dehydrogenated to produce benzene and its derivatives by heating them over catalysts.

One important consideration in any catalytic oxidation process at conditions of interest herein is the possible formation of hazardous incomplete oxidation products. One simple example is the formation of CI2 observed in the catalytic oxidation of methyl chloride over a-CrjOj/AljOj. Products that are even more toxic are of course possible. For all alcohols, aromatics, alkanes, aldehydes, naphthenes, ketones, and esters, the products of complete oxidation would of course be CO, and H,0. Although many VOCs are from these chemical classes, other associated compounds may lead to other products ...

Synthesis of Aromatic Alkanes (Friedel-Crafts Reaction)... 

In the presence of a chiral catalyst such as rhodium(II) (5)-/V l,8-naphthanoyl-tert-leucinate dimer, Troc-amino indane was produced with 56% yield and 2.57 1 enantiomeric ratio. In contrast to other methods, no hypervalent iodine reagent (typically used stoichiometrically or in excess and forming iodobenzene as by-product) is required for oxidation of the amine component. However, a slight excess of the aromatic alkane component (5 equiv) must be used to achieve good conversions. The reactivity of rhodium nitrenes generated from 2,2,2-trichloroethyl-/V-tosyloxycarbamate with aliphatic alkanes is similar to the one observed with metal nitrenes obtained from the oxidation of sulfamate with hypervalent iodine reagent. Troc-protected amino cyclohexane and cyclooctane were obtained, respectively, in 73 and 62% yields when 2 equiv of alkanes was used, whereas yields up to 85% were observed with 5 equiv (eq 3).

Most of the photocatalytic oxidations concern aliphatic and aromatic alkanes and alkenes derivatives, and the selective oxidation of alcohols to carbonyls. 

Two broad classes of lower volatility hydrocarbons have been studied extensively alkanes and polycyclic aromatics. Alkanes have been more systematically treated with regard to their potential for SOA formation, while the chemistry and... 

Other areas of application for binary ionic liquid mixtures may also be found in separation science, as shown in some pioneering work on the examples of aromatics/alkanes or gases [102, 103].
