Abstract
Aluminium oxide cross-linked montmorillonites, which have 17-19A of basal spacings and 350m2/g-500m2/g of specific surface areas were obtained. The synthesis was controlled by using solutions prepared at OH/Al=2. 1. After intercalating montmorillonite in the solution contained A113O4(OH)7+24 at room temperature, the product was subjected to the aging in water at 100°C for 5hr. It could be seen that the two step synthetic processes were indispensable for constructing Al13 polymers into the interlamella of clay.
The product had catalytic properties as acidic molecular sieves. When an ethanol reacted with the catalyst synthesized by the present study, it was confirmed that the oily substances were produced. According to the results of GS/MS and 1 H NMR measurements, the substances were composed of the aliphatic hydrocarbon having the molecular weight of above 300 and the networks of-(CH2)n-.
