trimethylsilylation reaction of olivine has yielded partial trimethylsilyl derivatives of ortho- and di-silicates whose unsilylated silanol groups have been esterified with the alcohol used as the organic solvent in the trimethylsilylating reagent. Gas chromatographic–mass spectroscopic measurements indicate the presence of the tri-, di-, and mono-alkyl-substituted trimethylsilyl derivatives of monosilicic
橄榄石的直接三甲基甲硅烷基化反应产生了原硅酸酯和二硅酸酯的部分三甲基甲硅烷基衍生物,其未甲硅烷基化的硅烷醇基团已被用作三甲基甲硅烷基化试剂中的有机溶剂的醇酯化。气相色谱-质谱分析表明,存在单硅酸[SiO 4(SiMe 3)4– n R n的三,二和单烷基取代的三甲基甲硅烷基衍生物。除了完全甲硅烷基化的单体衍生物[SiO 4(SiMe 3)4 ]外,n = 1-3]]。还发现了包含完全三甲基甲硅烷基化衍生物[Si 2 O 7(SiMe 3)6 ]和醇酯化衍生物[Si 2 O 7(SiMe 3)6– n R n的二聚体衍生物;n = 1-4]。酯化产物的比例随甲硅烷基化试剂中醇或水的体积以及反应时间而变化。
