H-mordenite, a more active acid catalyst than HZSM-5, showed features of a carbocationic/cationoidic isomerization in the reaction of liquid 3-methylpentane, but not of liquid hexane. The carbocationic isomerization features were not seen in the gas

Methyl tert-butyl ether (MTBE) is a widely used additive in oxygenated gasoline that has recently been identified as a potential health threat to the drinking water supply due to leaking underground storage tanks. One alternate use for MTBE is the pr

The mechanism of n-butane isomerization on a widely studied unpromoted sulfated zirconia catalyst was studied at low conversions in a once-through reactor using 13C-labeled n-butane as a reactant. The comparison of results from GC/MS analysis of isob

The probe bases used for measurement of strength of acid catalysts need to be structurally similar to the catalytic substrates. Traditional acidity measurements are inapplicable when the hydron transfer forms a tight ion pair, as on solid acids. Also

The main products of hexane (H) isomerization on HZSM-5 at 160°C in liquid phase are the isomers 2-methylpentane (2MP) and 3-methylpentane (3MP), accompanied by cracking and disproportionation products, but no alkenes. 2MP and 3MP are not formed by

Upon geometry optimization with no constraints (MP2/6-31G*), hydronium fluoroborate decomposed, but the dimer (H3O+·BF4−)2 was stable. In the dimer, the anions face each other and create a cavity containing the two cations. Density functional theo

The reaction of the 2-propyl cation with propene has been investigated by MP2/6-31G** and B3LYP/6-31G** calculations. An ion–molecule complex stabilized by 10–11 kcal mol−1 over the isolated reactants was identified. It continued over a barrier
