| | 2,2-Bis(3-amino-4-hydroxyphenyl)hexafluoropropane Usage And Synthesis |
| Description | 2,2-Bis(3-amino-4-hydroxyphenyl)hexafluoropropane (6FAP) is white
crystal. Its boiling point and density are expected to be 411.3±45.0 °C and 1.545±0.06 g/cm3, respectively. It is slightly soluble in DMSO and methanol.The product is non-toxic and can be stored at room temperature
away from light and air. | | Synthesis | 30 g two (3-nitro-4-hydroxyphenyl) hexafluoropropanes are dropped into
the 1000 mL autoclave, add 300 g DMF and 1.5 g palladium/carbon (the
mass fraction of palladium in the palladium/carbon is 5%), press
hydrogen to 1MPa, open stirring and be warmed up to 70 ℃, stop reaction
after two (3-nitro-4-hydroxyphenyl) hexafluoropropane content＜0.1%,
target product two (3-amino-4-hydroxyphenyl) hexafluoropropane
Fluoropropane gas phase content is 98%, and the system is black, and the
temperature of the still is lowered to room temperature, filtered, and
the filtrate is de-dried under reduced pressure at 70-80°C to obtain
bis(3-amino-4-hydroxyphenyl) hexafluoropropane crude product , the crude
product is recrystallized, the recrystallization solvent is water and
DMF, and the mass ratio of
bis(3-amino-4-hydroxyphenyl)hexafluoropropane, water and DMF is 1:4:2.
First, the bis(3-nitro-4-hydroxyphenyl) hexafluoropropane crude product
is mixed with the recrystallization solvent to increase the still
temperature to 60 °C and stir, and then the still temperature is reduced
to 10-20 °C for crystallization, filtered, After drying, 25.4 g of pure
bis(3-nitro-4-hydroxyphenyl)hexafluoropropane was obtained. The yield
of bis(3-amino-4-hydroxyphenyl)hexafluoropropane was 98.3% and the
purity was 99.6%. 1H-NMR (400MHz, D6-DMSO) δ (ppm): 4.64 (s, 4H), 6.42 (d, 2H), 7.57 (s, 2H), 6.65 (d, 2H), 9.36 (s, 2H). 19F-NMR (400MHz, D6-DMSO) δ (ppm): -62.78.
