“…However, these modifications have been typically based on the use of reactive alkylsilanes that contain organic groups. The alkylsilane-surface bonding stability, kinetic studies, bonding models and the reaction mechanisms of silylation have been thoroughly investigated [28,29]. The silylation of the interlayer surface of layered materials generated increased interest [30][31][32][33][34][35][36][37][38], with a number of authors exploring direct bentonite grafting reactions [39][40][41][42].…”

“…Corning controlled porous glass CPG-10 is used as a standard for porous adsorbents in studies of surface area and pore size distribution. Samples which were used as adsorbents in this work were modified using trimethyl chlorosilane (TMCS) triethyl chlorosilane (TECS) dimethyl dichlorosilane (DMDCS), and triphenyl chlorosilane (TPCS) in a similar way to that used in earlier vapour chemisorption kinetics' studies [23].…”

The interaction of ethanol vapour at 293 K with modified Corning controlled porous glass (CPG-10) samples of various pre-silylation is reported. Ethanol adsorption on CPG-10 was greatly reduced by silylation to extents largely depending on the silylation extent, type of silane used, and on the concentration and accessibility of residual silanols. The obtained adsorption isotherms, BET surface areas, as well as the observed changes at the various stages during the sorption particularly in the capillary condensation region also showed similar dependence. In the capillary condensation region, in the case of the dimethyl dichlorosilane-modified sample, hysteresis type was changed from H3 to H1. On the triethyl chlorosilane-modified sample an unexpected suppression of hysteresis effects occurred with a consequent transformation of type IV to type II adsorption isotherm.
