Ethyltoluene describes organic compounds with the formula CH3C6H4CH2CH3.
All are colorless liquids, immiscible in water, with similar boiling points.
[1] Ethyltoluenes are prepared by alkylation of toluene with ethylene: These alkylations are catalyzed by various Lewis acids, such as aluminium trichloride.
3- and 4-Ethyltoluenes are mainly of interest as precursors to methylstyrenes: This dehydrogenation is conducted in the presence of zinc oxide catalysts.
