Synthesis

60764-86-5

56706-10-6

General procedure for the synthesis of (3-mercaptopropyl)triethoxysilane (MPTES), compounds (CAS:60764-86-5) and bis-[3-(triethoxysilyl)propyl]-disulfide (TESPD) from 3-chloropropyltriethoxysilane (CPTES): during the reaction, 50 wt.% NaHSO4 was added drop-wise to a NaHS solution solution. 325 g (2.69 mol) of NaHS solution with 8.2 g (0.0124 mol) of tetrabutylammonium bromide (TBAB) solution were added to a glass reactor, mixed well and heated to 75 °C. Subsequently, NaHSO4 solution was added slowly and dropwise just before the imminent addition. Next, CPTES was added. 497.8 g (2.07 moles) of CPTES was added to the reaction mixture within 8 min. the addition of NaHSO4 solution needed to be completed within 30 min. After 5 hours of reaction, the organic phase was separated and analyzed by gas chromatography (GC). The analysis showed that the product contained 2.0% wt. of CPTES, 87.6% wt. of MPTES, 2.7% wt. of TESPM, and 0.7% wt. of TESPD.Finally, the product was distilled under vacuum to yield MPTES with a purity of 95.4%, which is about 84% yield based on the amount of CPTES used.
