반응 단계
2002.6 g of 3-mercaptopropyl(triethoxy)silane are mixed with 6108.5 g of hexadecanol as well as with 2 g of tetrabutyl orthotitanate and heated at 95-115° C. for 360 minutes in a 10 liter flask in a distillation apparatus. Ethanol formed in the transesterification is distilled off in vacuo at 15-600 mbar. After cooling, 7022 g of a colourless, solid product are obtained. As can be shown by 1H-NMR and 29Si-NMR, 92% of the EtO—Si groups are replaced by R—O—Si. In the transesterification more than 80 mole % of the ethanol-free compound [(C16H33O)3Si—C3H6—SH is formed, as can be shown for example by 1H-NMR and 29Si-NMR.
