초록
HZSM-5, synthesized in fluoride medium, showed high selectivity for the formation of 1,4-diethylbenzene (1,4-DEB) in the vapour phase ethylation of ethylbenzene (EB) with ethanol and hence becomes a convenient eco-friendly substitute for hazardous mineral acid catalysts. De-ethylation of EB to benzene was also minimized over this catalyst. As the medium pore size and presence of weak and medium acid sites might be the cause of such benefits, fluoride mediated synthesis of ZSM-5 is proven to be advantageous for para-selective alkylation of alkyl aromatics.
