Reaktionsschritte

Acetic acid (28.6 mL) and methoxy(ethoxyethoxy) acetic acid (76.7 mL) was dissolved in 500 mL of water and Vista Captal B boehmite (20 g) was slowly added and the solution was allowed to reflux for 72 hours. The solution was filtered and the filtrate was evaporated under reduced pressure resulting in a white/clear gel. The gel was dissolved in ethanol and the product was collected as a white powder upon the addition of diethyl ether. Yield: 25.4 g. The TGA of the product showed a 28.5% ceramic yield (weight loss of 71.5%). The alumoxane was heated from 25° C. to 200° C. at the rate of 1.5° C.min−1, soaked for 2 h. at 200° C. followed by a temperature ramp up to 1000° C. at the rate of 5° C.min−1, soaked for 2 h.
