WebQuestion: The production of ethylbenzene, a very popular industrial chemical, is carried out reacting benzene with ethylene in liquid phase. This reaction takes place in a series of reactors that involve multiple side reactions and intermediates. Ethylene, being the limiting reactant, is used up first and hence a considerable amount of benzene remains unreacted. WebEthylbenzene is produced by the alkylation of benzene with ethylene in the presence of an alkylation catalyst having a particular structure defined by its X-ray diffraction pattern. A preferred catalyst is the zeolite MCM-22. The process is typically carried out at a temperature of 300° to 1000° F. but the catalyst provides sufficient activity for the …

That's a higher proportion of the 3- isomer than you might expect. At 25°C, the proportions change to 3% / 69% / 28%. In other words the proportion of the 3- isomer has increased even more. proof bbq and booze
