Phenol - Wikipedia
Phenol is a component in liquid–liquid phenol–chloroform extraction technique used in molecular biology for obtaining nucleic acids from tissues or cell culture samples. Depending on the pH of the solution either DNA or RNA can be extracted. Phenol is so inexpensive that it also attracts many small-scale uses.
Phenol vs. Toluene — What’s the Difference?
2024年5月2日 · Key Differences. Phenol, characterized by its hydroxyl group attached to a benzene ring, exhibits mild acidic properties, useful in creating phenolic resins and pharmaceuticals. Whereas toluene, which has a methyl group instead of a hydroxyl, displays characteristics typical of aromatic hydrocarbons, like being a good solvent for paints. 12.
Toluene - Wikipedia
Toluene (/ ˈtɒl.juiːn /), also known as toluol (/ ˈtɒl.ju.ɒl, - ɔːl, - oʊl /), is a substituted aromatic hydrocarbon [15] with the chemical formula C6H5CH3, often abbreviated as PhCH3, where Ph stands for phenyl group. It is a colorless, water -insoluble liquid with the …
15.1: Naming Aromatic Compounds - Chemistry LibreTexts
Phenol is a benzene derived compound. Phenol can be made by attaching an -OH group to a phenyl group. Phenol is highly toxic to the body even in small doses. Phenol can be used as a catalyst in the hydrogenation of benzene into cyclohexane. Phenol is …

15.1 Naming Aromatic Compounds - Organic Chemistry - OpenStax
Any of the monosubstituted aromatic compounds shown in Table 15.1 can serve as a parent name, with the principal substituent (–OH in phenol or –CH 3 in toluene) attached to C1 on the ring. Problem 15-1. Tell whether the following compounds are ortho-, meta-, or para-disubstituted: (a) (b) (c) Problem 15-2.
15.3: Nomenclature of Benzene Derivatives - Chemistry LibreTexts
According to the indexing preferences of the Chemical Abstracts, phenol, benzaldehyde, and benzoic acid (labeled in red in Figure 16) are some of the common names that are retained in the IUPAC (systematic) nomenclature. Other names such as toluene, styrene, naphthalene, or phenanthrene can also be seen in the IUPAC system in the same way.
Oxidizing toluene to phenol - Chemistry Stack Exchange
2024年4月27日 · Toluene oxidation is a two-step process. According to Ullmann’s Encyclopedia of Industrial Chemistry (sixth edition), the first step is the oxidation of toluene with atmospheric oxygen to benzoic acid, which is carried out in the liquid phase at temperatures of about 100–150 °C and an absolute pressure of about 3 bar.

5 天之前 · The presence of the hydroxy group in phenol gives rise to much higher melting and boiling points and to solubility compared with those of benzene and toluene. Phenol can be synthesized from the distillation of coal tar or from the hydrolysis of …
Phenol | Definition, Structure, Uses, & Facts | Britannica
Phenol, any of a family of organic compounds characterized by a hydroxyl group attached to a carbon atom that is part of an aromatic ring. Besides serving as the generic name for the entire family, the term phenol is also the specific name for its simplest member, monohydroxybenzene, also known as benzenol.
