Yield:461-68-7 99.1%
Reaction Conditions:
with potassium oxide at 200; for 10 h;Autoclave;
Steps:
1.2 Step (2):
In a 1 liter, 316 material autoclave, first add 0.5 mol of potassium oxide, after vacuuming, at room temperature and stirring conditions, quickly 0.1 mol of hexafluoroglutarate fluoride, the feeding is complete After that, the temperature was raised to 200°C for 10 hours of reaction time. After the reaction, the gas phase product tetrafluoropropadiene in the reaction system was collected with a 200mL small steel bottle made of 316 material. The yield was 99.1% and the purity was 99.6% (GC analysis) .
