Versuchsvorschrift

In a 500 ml three-neck flask provided with a magnetic stirrer and a reflux condenser were charged 19.6 g (0.0841 mole) of cyclopentyl triethoxysilane, 98.0 g (1.63 mole) of isopropyl alcohol and 198.7 mg (2.92 m mole) of sodium ethoxide, which were then reacted with each other at room temperature for 2 hours under stirring. Then, trimethylchlorosilane was added to neutralize the alkali. Then, 9.56 g (0.0388 mole) of isopropoxy cyclopentyl diethoxysilane were obtained by vacuum distillation. Its structure was confirmed as in Example 1. Tile yield was 46%.
