Abstract
Silanol groups in the mesoporous silica derived from a layered silicate, kanemite (NaHSi2O5 · 3H2O), were esterified with alcohols (CnH2n+1OH; n = 2, 4, and 8). Most of the silanol groups in the mesopores were modified with ethanol though some silanol groups remained after the reactions with 1-dutanol and 1-octanol. With the increase in the alkyl chain lengths of the alcohols, the pore sizes of the esterified products decreased and the hydrophobicity increased.
