nitration of benzene and methylbenzene chemguide
Toluene (or methylbenzene) is a commonly used organic solvent; it is less carcinogenic than benzene because the methyl group is easily oxidized, and can be converted to products that can be eliminated from the body with relative ease....

An alternative method to prepare benzene from toluene is hydrodealkylation. Reactors compress toluene and hydrogen to pressures between 20 and 60 atmospheres and heat the mixture to temperatures between 930 and 1,220 degrees Fahrenheit.
- Toluene or methylbenzene is a clear, water-insoluble organic liquid, used as paint thinner and organic solvent. It is an aromatic hydrocarbon. The methyl group makes toluene around 25 times more... It is an aromatic hydrocarbon.
- Your friends are correct. The most common way to convert toluene directly to benzaldehyde is "Etard reaction." Reagent is chromyl chloride-CrO 2 Cl 2.
- Substitution Reactions of Benzene and Other Aromatic Compounds. The remarkable stability of the unsaturated hydrocarbon benzene has been discussed in an earlier section. The chemical reactivity of benzene contrasts with that of the alkenes in that substitution reactions occur in preference to addition reactions, as illustrated in the following diagram (some comparable reactions of cyclohexene
- Benzaldehyde Toluene It is an aromatic hydrocarbon that is widely used as an industrial feedstock and as a solvent. Like other solvents, toluene is also used as an inhalant drug for its intoxicating properties; however this causes severe neurological harm.
