[0117]According to the moisture mass ratio, each component was calculated: take a certain amount of acetone in a single-mouth flask, add 5-8 mol of potassium carbonate suspended in acetone, 1.5-4 mol acrylic acid, 1-2 mol of pentafluoride, 0.1 ~ 0.3 Mmol 2,6-di-tert-butyl phenol. Condensation of 65 ° C for 3 hours, the reaction was completed, filtered, the residue was dissolved in diethyl ether, and extracted with water, the aqueous phase was eluted with sodium bicarbonate and water, and the organic phase was removed with anhydrous sodium sulfate to remove the solvent. Finally, the product acrylate pentafluorine was isolated by column chromatography.
