실험 절차
47.5 g of bis-[γ-(triethoxysilyl)-propyl]-disulfide (0.1 mole) was heated together with 3.2 g of sulfur (0.1 mole) under a nitrogen gas atmosphere for about 15 hours at about 150°C, until all of the sulfur had dissolved and did not crystallize out again upon cooling. A dark red liquid was formed, which a thin-layer chromatogram showed to contain no free sulfur, and in which disulfides and tetrasulfides are dissolved as shown by mass spectrographic analysis.
