Shape-selective reactions with zeolite catalysts: V. Alkylation or disproportionation of ethylbenzene to produce ϱ-diethylbenzene
Alkylation of ethylbenzene (EB) with ethylene produces diethylbenzene (DEB) over ZSM-5 zeolite catalysts. Disproportionation of EB over these catalysts gives benzene and DEB. Less ortho-DEB forms than expected for equilibrium. Large-crystal ZSM-5 gives higher concentrations of para-DEB (PDEB) than s...

Summary: | Alkylation of ethylbenzene (EB) with ethylene produces diethylbenzene (DEB) over ZSM-5 zeolite catalysts. Disproportionation of EB over these catalysts gives benzene and DEB. Less
ortho-DEB forms than expected for equilibrium. Large-crystal ZSM-5 gives higher concentrations of
para-DEB (PDEB) than small-crystal ZSM-5. Alkylations and disproportionation over ZSM-5 modified with magnesium and phosphorus yield 98–99+% PDEB. These observations establish the elements necessary for development of a commercial PDEB process. |
