In this study, polyketone anion exchange fibers were synthesized by the amination of polyketone via a Paal-Knorr reaction and a quaternization reaction. The amination reaction proceeded at different reaction times and amine N,N-dimethylethylene diamine (DME) concentrations. The ion exchange capacity (IEC) and water uptake (W.U.) increased with increasing amination reaction time and DME concentration, and the maximum IEC and W.U. were 1.03 meq/g and 19.2%, respectively. The tensile strength decreased significantly with increasing amination time and amine concentration. TGA showed that the thermal decomposition temperature of the fibers was 220 °C. The HCl gas adsorption properties of the aminated polyketone ion exchange fibers were evaluated, and the HCl gas removal efficiency remained at 100% in 40 min at 300 ppm.

Paal-Knorr反应合成聚酮阴离子交换纤维及其理化性质

在这项研究中，聚酮阴离子交换纤维是通过Paal-Knorr反应和季铵化反应将聚酮胺化而合成的。胺化反应在不同的反应时间和胺N，N进行-二甲基乙二胺（DME）浓度。离子交换容量（IEC）和吸水率（WU）随着胺化反应时间和DME浓度的增加而增加，最大IEC和WU分别为1.03 meq / g和19.2％。随着胺化时间和胺浓度的增加，拉伸强度显着降低。TGA表明纤维的热分解温度为220℃。评估胺化的聚酮离子交换纤维的HCl气体吸附性能，并在300分钟内40分钟内将HCl气体去除效率保持在100％。
