predominantly Si2O7(SiMe3)x(Pri)6–x(x= 2–6), and Ca3[Si3O9] gave predominantly Si3O9(SiMe3)x(Pri)6–x(x= 2–6) and Si3O10(SiMe3)x(Pri)8–x(x= 3–8). Mixed trimethylsilyl–isopropyl derivatives were converted to the fully trimethylsilylated derivatives SiO4(SiMe3)4, Si2O7(SiMe3)6, and Si3O10(SiMe3)8 on treatment with Amberlyst 15 ion-exchange resin in the presence of hexamethyldisiloxane. In the trimethylsilylation
详细研究了在不同条件下原硅酸钙(Ca 2 [SiO 4 ]),变质岭石(Ca 3 [Si 2 O 7 ])和假硅灰石(Ca 3 [Si 3 O 9 ])的三甲基甲硅烷基化的产率和产物。实验条件。以六甲基二硅氧烷,氯代三甲基硅烷和异丙醇为试剂,在不添加水的情况下,Ca 2 [SiO 4 ]主要产生SiO 4(SiMe 3)x(Pr i)4– x(x = 1-4),而数量较少的硅2 O 7(SiMe 3) x(Pr i) 6– x( x = 2–6),Ca 3 [Si 2 O 7 ]主要产生Si 2 O 7(SiMe 3) x(Pr i) 6– x( x = 2–6),而Ca 3 [Si 3 O 9 ]主要产生Si 3 O 9(SiMe 3) x(Pr i) 6– x(x = 2–6)和Si 3 O 10(SiMe 3)x(Pr i)8– x(x = 3–8)。在使用Amberlyst 15离
