Paragraph 0030-0032, (2021/11/21)
The invention discloses a bisphenol F 2222,dihydroxypropyl (2 -chloro -1 - propyl) diethyl ether method which comprises the following steps S1) adding bisphenol F, epichlorohydrin, potassium hydroxide and tetrabutylammonium bromide into a reaction container. S2) The obtained material is diluted with ethyl acetate, then washed with water, the organic phase is separated, and the bisphenol F glycidyl ether is obtained by purification and separation. S3) A mixture of bisphenol F glycidyl ether, tin dichloride dihydrate and diethyl ether is added to the reactor. S4) The obtained material is diluted with ethyl acetate, then washed with water, the organic phase is separated, and the bisphenol F glycidyl ether is obtained by purification and separation. S5) The obtained material and distilled water are added to the reaction vessel to react. S6) The obtained material is extracted and separated by ethyl acetate to obtain an organic phase, and the organic phase is purified and separated to obtain the organic phase. The raw materials are easy to obtain, and the reaction conditions are mild. Target product purity is high, aftertreatment is simple and convenient and green.
