Potassium phthalimide, 16.7 grams (0.09 mols) and 70 g of Parrafine are added to the filtrate. The flask is fit with a thermometer, 30 cm-packed column, vacuum-column-head and vacuum line. A 300 mbar vacuum is achieved and the mixture is heated to a pot-temperature of 35° C., gradually rising to 60° C., retaining a columnhead temperature of 32-34° C. (at which temperature acetone and triethylamine are distilled off). The vacuum is brought to 11-17 mbar and a small fraction of acetone and triethylamine is taken. The pot temperature is then raised to 70° C., gradually rising to 130° C., retaining a head temperature of 60-70° C. (depending on the vacuum). Vinyltriisopropenoxysilane, 97.8 grams (0.43 mols, 72percent yield), is collected and stored under nitrog |
