Embodiment 1
[0028] 36.6 grams (0.10 moles) of 2,2-bis(3-amino-4-hydroxyphenyl) hexafluoropropane, 44.6 grams (0.22 moles) of 2,4-dinitrochlorobenzene, 110.4 grams (0.80 moles) Potassium carbonate, 700 milliliters of N,N-dimethylformamide and 180 milliliters of toluene were put into the reaction kettle, under nitrogen atmosphere, stirred, heated to reflux for water separation and reacted for 18 hours, concentrated the reaction solution, recovered the solvent for recycling, and cooled the reaction After adding water, the solid product was precipitated, washed 2 to 3 times with hot water, and dried to obtain 2,2-bis[3-amino-4-(2,4-dinitrophenoxy)phenyl]hexafluoro Propane, the purity is 99.1%, according to the actual amount and theoretical amount of 2,2-bis[3-amino-4-(2,4-dinitrophenoxy)phenyl]hexafluoropropane, 2 is calculated, The yield of 2-bis[3-amino-4-(2,4-dinitrophenoxy)phenyl]hexafluoropropane was 98.1%.
Embodiment 2
[0030] 36.6 grams (0.10 moles) of 2,2-bis(3-amino-4-hydroxyphenyl) hexafluoropropane, 54.4 grams (0.22 moles) of 2,4-dinitrobromobenzene, 55.2 grams (0.40 moles) Potassium carbonate, 150 milliliters of N, N-dimethylacetamide and 15 milliliters of dimethylbenzene were put into the reaction kettle, under nitrogen atmosphere, stirred, heated to reflux and separated from water for 6 hours, concentrated the reaction solution, recovered the solvent for recycling, cooled The reactant system was added with water to precipitate a solid product, which was washed 2 to 3 times with hot water and dried to obtain 2,2-bis[3-amino-4-(2,4-dinitrophenoxy)phenyl]6 Fluoropropane, with a purity of 99.5%, is calculated based on the actual amount and theoretical amount of 2,2-bis[3-amino-4-(2,4-dinitrophenoxy)phenyl]hexafluoropropane. , the yield of 2-bis[3-amino-4-(2,4-dinitrophenoxy)phenyl]hexafluoropropane was 72.3%.
Embodiment 3
[0032] 36.6 grams (0.10 moles) of 2,2-bis(3-amino-4-hydroxyphenyl) hexafluoropropane, 40.5 grams (0.20 moles) of 2,4-dinitrochlorobenzene, 10.6 grams (0.10 moles) Sodium carbonate, 60 milliliters of N-methyl-2-pyrrolidone and 23 milliliters of dichlorobenzene were put into a reaction kettle, under a nitrogen atmosphere, stirred, heated to reflux for water separation and reacted for 16 hours, concentrated the reaction solution, recovered the solvent for recycling, Cool the reactant system, add water, precipitate a solid product, wash with hot water 2 to 3 times, and dry to obtain 2,2-bis[3-amino-4-(2,4-dinitrophenoxy)phenyl] Hexafluoropropane, with a purity of 99.2%, is calculated according to the amount and theoretical yield of 2,2-bis[3-amino-4-(2,4-dinitrophenoxy)phenyl]hexafluoropropane actually obtained The yield of 2,2-bis[3-amino-4-(2,4-dinitrophenoxy)phenyl]hexafluoropropane was 94.2%.
