Examples
Embodiment 1
[0042] At normal temperature and pressure, add pyrrole (0.2ml) and chloroform (20ml) into a 100ml Erlenmeyer flask and mix thoroughly, add ferric chloride (2901mg) and nitromethane (20ml) into another small beaker, mix and dissolve . Then keep the Erlenmeyer flask with pyrrole and chloroform at 20°C under a water bath and stir it, add the mixed solution of ferric chloride and nitromethane dropwise (1-5 drops / 5 minutes), and cover it after adding The glass stopper was sealed and reacted for 24 hours, then anhydrous methanol (50ml) was added and stirring was continued for 1 hour. Purify after the reaction, extract with methanol for 24 hours, then extract with chloroform for 24 hours, and finally dry in vacuum at 60°C for 24 hours to obtain pyrrolyl-conjugated microporous polymer powder with a specific surface area of 739m 2 / g, for CO at 273K, 1.0bar and 298K, 1.0bar 2 Adsorption reached 9.6 wt% and 5.6 wt%, respectively.
Embodiment 2
[0044]At normal temperature and pressure, pyrrole (0.2ml) and chloroform (20ml) were added into a 100ml Erlenmeyer flask and mixed thoroughly, and ferric chloride (2901mg) and chloroform (20ml) were added into another small beaker, mixed and dissolved. Afterwards, keep the Erlenmeyer flask with pyrrole and chloroform at 20°C under a water bath and stir it, add the mixed solution of ferric chloride and nitromethane dropwise (1-5 drops / 5 minutes), and cover it after adding The glass stopper was sealed and reacted for 24 hours, then anhydrous methanol (50ml) was added and stirring was continued for 1 hour. Purify after the reaction, extract with methanol for 24 hours, then extract with chloroform for 24 hours, and finally dry in vacuum at 60°C for 24 hours to obtain pyrrolyl-conjugated microporous polymer powder with a specific surface area of 177m 2 / g, for CO at 273K, 1.0bar and 298K, 1.0bar 2 Adsorption reached 4.8 wt% and 3.2 wt%, respectively.
Embodiment 3
[0046] At normal temperature and pressure, add pyrrole (0.2ml) and nitromethane (20ml) into a 100ml Erlenmeyer flask and mix thoroughly, add ferric chloride (2901mg) and nitromethane (20ml) into another small beaker Mix to dissolve. Then keep the Erlenmeyer flask with pyrrole and chloroform at 20°C under a water bath and stir it, add the mixed solution of ferric chloride and nitromethane dropwise (1-5 drops / 5 minutes), and cover it after adding The glass stopper was sealed and reacted for 24 hours, then anhydrous methanol (50ml) was added and stirring was continued for 1 hour. Purify after the reaction, extract with methanol for 24 hours, then extract with chloroform for 24 hours, and finally dry in vacuum at 60°C for 24 hours to obtain pyrrolyl-conjugated microporous polymer powder with a specific surface area of 326m 2 / g, for CO at 273K, 1.0bar and 298K, 1.0bar 2 Adsorption reached 6.0 wt% and 3.9 wt%, respectively.
