C6H5CH3+ H2→ C6H6+ CH4. Hydrodealkylation strips the methyl group from toluene to produce benzene. Toluene disproportionation involves combining toluene so that the methyl groups bond to one aromatic ring, producing benzene and xylene. Benzene can also be obtained from petroleum reforming in which...
Benzene is known for its unique structure, consisting of a ring of six carbon atoms, each bonded to a hydrogen atom. This cyclic arrangement of atoms gives benzene its stability and reactivity, making it an important building block in organic chemistry. Benzene is a key component in the ...
Benzene (C₆H₆) is a colorless liquid with a sweet odor, which is highly flammable and has a characteristic aromatic smell. It is a stable, cyclic hydrocarbon composed of six carbon atoms bonded to six hydrogen atoms in a ring structure. Benzene is liquid at room temperature and has ...
During the decomposition of methane in CVI, benzene is a basic element of pyrolytic aromatic hydrocarbons which can further form the pyrocarbon, thus the present work is performed by limiting the reaction route only to the first cyclic ring formation. In this work, a DFT study was employed to...

Fraction 2 was divided into four subfractions (Frs. 2-1–2-4) by semipreparative HPLC using step gradient elution with CH3CN/H2O (0.4% TFA, 65–85%, v/v, 0–30 min). Subfraction 2-1 was further purified by semipreparative HPLC (68% CH3CN/H2O (0.4% TFA), 2 mL/min) to ...
And say that one of them is anortho-, para-director and one is ameta-director, and they “direct” electrophiles to different carbons on the ring? Which directing group “wins?”. 2. An Easy One:p-Nitroanisole Let’s start with 1-methoxy-4-nitrobenzene, which also goes by the name...
