Methanol is primarily converted to formaldehyde, which is widely used in many areas, especially polymers. The conversion entails oxidation: 2 CH 3 OH + O 2 → 2 CH 2 O + 2 H 2 O. Acetic acid can be produced from methanol. The Cativa process converts methanol into acetic acid. [35] Methanol and isobutene are combined to give methyl tert-butyl ...
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 ...
Data obtained from Lange's Handbook of Chemistry, 10th ed. and CRC Handbook of Chemistry and Physics 44th ed. The annotation, d a°C/b°C, indicates density of solution at temperature a divided by density of pure water at temperature b known as specific gravity. When temperature b is 4 °C, density of water is 0.999972 g/mL.
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.
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 ...
For example, NaC 6 H 5 CO 2, the sodium salt of benzoic acid (C 6 H 5 COOH), is called sodium benzoate. Where an acid has both a systematic and a common name (like CH 3 COOH, for example, which is known as both acetic acid and as ethanoic acid), its salts can be named from either parent name.
The chart was again modified in 2010, moving the Aromatics section to in between Dry Woods and Citrus to synchronize the official chart [9] with recent studies on smell perception. [ 10 ] [ 11 ] [ 12 ] The groupings are rough, and overlapped according to different sources.
