실험 절차

221.0 g (1.0 mol) of 3-aminopropyltriethoxysilane were introduced into a standard stirrer apparatus. 172.0 g (1.0 mol) of maleic acid diethyl ester were added dropwise at room temperature over a period of about 4 hours. The exothermic reaction was maintained at about 30° C. by cooling the apparatus in a water bath. Stirring was then continued for a further 8 hours at room temperature. A clear, colorless liquid having a viscosity of about 30 mPa.s (23° C.) was obtained. Base titration showed almost complete conversion. The amine equivalent weight was about 398 g (theory: 393 g).
