The reaction of triorganyl(dimethylamino)silanes with surface-hydrated silicon dioxide has been studied. These silylating agents are easy to prepare from the corresponding chloro or bromosilanes with dimethylamine. The resulting products are thermally stable and relatively volatile. Reaction with surface-hydrated silicon-dioxide preparations at 150–250°C for 170 h yields a dense grafted layer. However
研究了三有机基(二甲基氨基)硅烷与表面水合二氧化硅的反应。这些甲硅烷基化剂易于由相应的氯硅烷或溴硅烷与二甲胺制备。所得产物是热稳定的和相对挥发性的。在150–250°C下与表面水合二氧化硅制备物反应170 h,得到致密的接枝层。然而,对于具有强极性取代基的(二甲基氨基)硅烷而言,为了获得最大的覆盖率,似乎有必要对表面改性的二氧化硅进行重新处理。
