The second chemical class is composed of the fatty acid derivatives synthesized from acetyl-CoA, most of which are known as green leaf volatiles, because they are also emitted by vegetative parts (i.e.: leaves and stems) of plants, and sometimes higher in abundance than from floral tissue.
Catalytic reforming usually utilizes a feedstock naphtha that contains non-aromatic hydrocarbons with 6 to 12 carbon atoms and typically produces a reformate product containing C 6 to C 8 aromatics (benzene, toluene, xylenes) as well as paraffins and heavier aromatics containing 9 to 12 carbon atoms.
Heteroarenes are aromatic compounds, where at least one methine or vinylene (-C= or -CH=CH-) group is replaced by a heteroatom: oxygen, nitrogen, or sulfur. [3] Examples of non-benzene compounds with aromatic properties are furan, a heterocyclic compound with a five-membered ring that includes a single oxygen atom, and pyridine, a heterocyclic compound with a six-membered ring containing one ...
Aromatization is a chemical reaction in which an aromatic system is formed from a single nonaromatic precursor. Typically aromatization is achieved by dehydrogenation of existing cyclic compounds, illustrated by the conversion of cyclohexane into benzene. Aromatization includes the formation of heterocyclic systems. [1]
Methanol Synthesis: Syngas is fed to Reactor 1, the first of four reactors, which converts most of the syngas to methanol when passing through the catalyst bed. CO + 2 H 2 → methanol CH 3 OH Dimethyl Ether (DME) Synthesis: The methanol-rich gas from Reactor 1 is next fed to Reactor 2, the second STG+ reactor.
In organic chemistry, the aromatic alcohols or aryl-alcohols are a class of chemical compounds containing a hydroxyl group (−O H) bonded indirectly to an aromatic hydrocarbon group, [1] in contrast to the phenols, where the hydroxyl group is bonded directly to an aromatic carbon atom. [2] Aromatic alcohols are produced by the yeast Candida ...
Methanol (also called methyl alcohol and wood spirit, amongst other names) is an organic chemical compound and the simplest aliphatic alcohol, with the chemical formula C H 3 OH (a methyl group linked to a hydroxyl group, often abbreviated as MeOH).
Chemical investigation of methanol extracts from Pithecoctenium crucigerum (Bignoniaceae) showed the presence of five phenylethanoid glycosides (verbascoside, isoverbascoside, forsythoside B, jionoside D and leucosceptoside B), these all active against DPPH.
