実験手順
3-Aminopropyltrimethoxysilane (20 g, 0.111 mol) was mixed with propylene carbonate (11.39 g, 0.111 mol) under slow stirring. The mixture became slightly warm. Stirring continued for 24 hours to give 2-hydroxylpropyl N-(3-trimethoxysilylpropyl)carbamate. 2-Methyl-1-3 propanediol (38.8 g, 0.431 mol) was added drop-wise under stirring to a mixture of 2-hydroxylpropyl N-(3-trimethoxysilylpropyl)carbamate (31.4 g, 0.111 mol) and sulfuric acid (0.1 g) and then heated at 50° C. and 15 mm Hg pressure for 4 hours. The methanol that formed was removed by distillation. The product was a clear and slightly viscous liquid.
