실험 절차

Example 8 was repeated using the same reactor and catalyst/support charge. CF3CF2CF2OCF(CF3)CO2SiMe3 (128.6 g, 0.320 mmol) was added dropwise at ca. 20 g/hr using N2 carrier flow of 34 mL/min. There was obtained 109.1 g of liquid product consisting of PPVE (49.4 mole %), TMSF (48.4%) and C3F7OCHFCF3 (2.2%). Distillation using a 24" spinning band column gave 23.9 g of an azeotrope (74/26 TMSF/PPVE by weight), 23.5 g of intermediate fractions, and 51.6 g of >99.8% purity PPVE.
