Layered niobium molybdate (HNbMoO6) was used in the aqueous-phase dehydration of sorbitol and was found to exhibit remarkable selectivity toward its monomolecular-dehydrated intermediate 1,4-sorbitan. This was attributed to the selective intercalation of sorbitol within the interlayers with strong Brønsted acid sites. The power of intercalation: The aqueous-phase dehydration of a sugar alcohol, sorbitol, to its monomolecular dehydrated intermediate, 1,4-sorbitan, with high selectivity is described for the use of a unique solid acid, HNbMoO6. The activity and selectivity to 1,4-sorbitan is superior to those obtained on other solid acids, including protonic zeolites, niobic acid, and ion-exchange resins. This improvement is attributable to the control intercalation selectivity.
