摘要：

The adsorption properties of the clathrasil Deca-dodecasil 3R (DD3R) have been studied. This porous tectosilicate becomes microporous when the organic template 1-adamantanamine is removed by calcination, which gives this clathrasil zeolitical properties. By means of adsorption of water, DD3R has been proven to be very hydrophobic. These adsorption data, together with the isosteric heats of adsorption of carbon dioxide at different loadings, reveal the absence of strong adsorption sites for polar or polarizable molecules, in contrast to the adsorbent zeolite A.
