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 ...
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 ...
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.
In chemistry, an alcohol (from Arabic al-kuḥl 'the kohl'), [2] is a type of organic compound that carries at least one hydroxyl (−OH) functional group bound to a saturated carbon atom. [3] [4] Alcohols range from the simple, like methanol and ethanol, to complex, like sugars and cholesterol. The presence of an OH group strongly modifies the ...
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.
It is typically used in the reduction of compounds with multiple bonds, such as alkynes, alkenes, [19] nitriles, [20] dienes, aromatics [21] and carbonyl-containing compounds. Additionally, Raney nickel will reduce heteroatom-heteroatom bonds, such as hydrazines , [ 22 ] nitro groups, and nitrosamines. [ 23 ]
In space methoxymethanol can form when methanol radicals (CH 2 OH or CH 3 O) react. These are radiolysis products derived when ultraviolet light or cosmic rays hit frozen methanol. [3] Methanol can react with carbon dioxide and hydrogen at 80°C and some pressure with a ruthenium or cobalt catalyst, to yield some methoxymethanol. [5]
In chemistry, a structural isomer (or constitutional isomer in the IUPAC nomenclature [1]) of a compound is another compound whose molecule has the same number of atoms of each element, but with logically distinct [clarification needed] bonds between them. [2] [3] The term metamer was formerly used for the same concept. [4]
