Ethyltoluene is produced by ethylation of toluene:
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.[1]
4-Ethyltoluene is subjected dehydrogenation to give 4-vinyltoluene.[2]
