Synthesis, characterization, and catalytic activity of beidellite–montmorillonite layered sillcates and their pillared analogues

Abstract

A Synthetic beidellite-smectite, characterized by a range of techniques, including high-resolution ²⁷Al ans ²⁹Si solid-state n.m.r. spectroscopy, shows interesting catalytic activity (in secondary amine formation from cyclohexylamine, in ester production from hex-1-ene and acetic acid, and in ether synthesis from pentanol): the selectivities differ significantly from those of montmorillonite-smectites.
