Pillared synthetic boron-containing saponite

Preparation and Properties of Pillared Synthetic Boron-Containing Saponite... 

Pillaring selected synthetic clay minerals with suitable pillaring agents may lead to a breakthrough in the theory and application of pillared clays. This chapter reports on the preparation and characterization of a novel pillared synthetic heteroatom-containing clay, that is, pillared synthetic boron-containing saponite. 

Characterization of the pillared synthetic (boron-containing) saponites...

Alumina-pillared synthetic boron-containing s qx)nite was prepared for the first time. The introduction of boron into the S2qx)nite layers markedly enhanced both cumene dealkylation activity and benzene selectivity of its pillared product The pillared product of synthetic boron-containing saponite was pillared clay rather than delaminated clay.
