Firstly, a model is proposed for the surface of highly dispersed silicon dioxides (Aerosil, Cabosil). In the first part, the investigation of the uncatalysed reaction of the surface hydroxyls on Cabosil with alkyl and oxa-alkyldimethylsilanols is described. The reaction mechanism is discussed on the basis of kinetic measurements. The reaction attains a limiting surface concentration of 3.1 μmol m−2 of alkyldimethylsiloxy groups, a value which is independent of the chain length of the non… CONTINUE READING
