制备BET比表面积为1019.08m~2/g、微孔面积为844.44m~2/g的超高交联树脂(简记为 H-06),研究H-06超高交联树脂的超声辅助磺化。以负载的磺酸基团为评价指标,H-06超高交联树脂超声辅助磺化的最优条件为:二甲亚砜为溶胀剂、反应温度为80℃、超声功率为180W、硫酸浓度为92.5%、树脂与硫酸用量比为1:5、超声时间为1.5h。最优条件下超声辅助磺化树脂(简记为GQ-07)磺酸基团负载量为1.75m mol/g、BET比表面积为553.69m~2/g、微孔面积为483.48m~2/g。非超声辅助磺化树脂(简记为H-07)磺酸基团负载量为0.75m mol/g、BET比表面积为589.91m~2/g、微孔面积为514.34m~2/g。4种超高交联树脂对2-氨基酚的吸附量顺...

The objective of this work was to investigate the ultrasound assisted sulfonation of the hyper-cross-linked resin H-06, which was of BET surface area 1019.08m2/g and micropore area 844.44m2/g. The amount of sulfonic acid groups uploaded onto resin was taken as evaluation index to investigate the effects of the ultrasound assisted sulfonation. Results showed that the optimum ultrasound sulfonation conditions were as follows: Dimethyl sulfoxide as swelling agent, reaction temperature 80℃, ultrasonic power 180W, 92.5% H2SO4, ratio of resin to sul...
