4-Ethyltoluene is an organic compound with the formula CH3C6H4C2H5. It is one of three isomers of ethyltoluene, the other two isomers being 3-ethyltoluene and 2-ethyltoluene. All are colorless liquids and all are used for the production of specialty polystyrenes.
==Production and use== Ethyltoluene is produced by ethylation of toluene: CH3C6H5 + C2H4 → CH3C6H4C2H5 Over typical acid catalysts, this process gives a mixture of the 2-, 3-, and 4- isomers. Using a modified zeolite catalyst, the alkylation is shape-selective for the 4- isomer.
