WebThe resulting linear mono-olefins react with benzene in the presence of a catalyst to produce the LABs. Hydrogen fluoride (HF) and aluminium chloride (AlCl 3) are the two major catalysts for the alkylation of benzene with linear mono-olefins. WebEthylbenzene is produced on a large scale by combining benzene and ethene in an acid-catalyzed chemical reaction : C 6H 6 + C 2H 4 → C 6H 5CH 2CH 3 In 2012, more than 99% of ethylbenzene was produced in this way. Thus, makers of ethylbenzene are the major buyers of benzene, claiming more than half of total output. [5]
