BISPHENOL F DIGLYCIDYL ETHER synthesis

Yield:2095-03-6 80%

Reaction Conditions:

with tetrabutylammomium bromide;potassium hydroxide at 20; for 12 h;

Steps:

Put bisphenol F (10mmol, 2g) into a 50mL round bottom flask,Add epichlorohydrin (25mmol, 8mL),Then slowly add potassium hydroxide (3.0g, 55mmol) to the mixture,Then tetrabutylammonium bromide (0.7 g, 2.2 mmol) was added.Stir the mixture system at room temperature for 12h. The reaction was detected by TLC,after the end,The reaction solution was diluted with ethyl acetate,Wash three times,The organic phase is dried with anhydrous Na2SO4,filter,concentrate,Purified by column chromatography to obtain 2.5 g of the target product,The yield was 80%. The structure of the compound is determined by standard control
