单功能基叔胺型弱碱树脂的合成及其滴定曲线研究
STUDIES OF THE SYNTHESIS OF WEAK-BASE ION EXCHANGER WITH HOMO TERTIARY AMINE GROUPS AND ITS TITRATION CHARACTERISTIC
【摘要】 合成了以苯乙烯-二乙烯苯为骨架的若干叔胺型弱碱性树脂,研究了胺化反应条件、胶化试剂及交联度等对叔胶型弱碱树脂功能基单一性的影响,测定了强碱交换量低的叔胺树脂的滴定曲线特征,找到了适合作为热再生树脂弱碱组分的单功能基叔胶树脂的合成条件.
【Abstract】 Some weak-base ion exchangers with tertiary amine groups were synthesized fromstyrene and divinylbenzene, the effect of aminolysis condition, aminolysis agent andcrosslinking degree on the homo-functionality of these ion exchangers with small strong basecapacities were also investigated. The weak base ion exchanger with largest homo-functionalitywas synthesized and suitable for the preparaion of thermally regenerable amphoteric ionexchanger.
