摘要
由聚苯乙烯基磺酰氯树脂与硫化氢钾反应制备聚苯乙烯基硫代磺酸钾树脂（Ⅰ）,树脂Ⅰ与亲电的卤代烃反应,生成聚苯乙烯基硫代磺酸酯树脂（Ⅱ）,树脂Ⅱ经过乙硫醇处理,使卤代烃结构部分以不对称二硫醚的形式游离下来,用GC/MS对其结构进行鉴定,从不对称二硫醚的结构可推导出原卤代烃的结构,所制备的聚苯乙烯基硫代磺酸钾树脂的转化效率为1.11mmol·g^(-1)。
Potassium polystyrylthiosulfonate resin (I) was prepared from the reaction of polystyrylsulfonyl chloride with KHS. Resin I reacted with electrophilic halogenated hydro-carbons to produce polystyrylthiosulfonic esters resin (Ⅱ). The resin Ⅱ were treated with excess mercaptan and the structure parts of the helogenated hydrocarbons were dissociated from the resin as unsymmetrical disulfides which were determined by GC-MS. The structure of the original halogenated hydrocarbons could be deduced from that of unsymmetrical disulfide obtained. The capacity of the potassium polystyrylthiosulfonate resin prepared is 1.11 mmol·g-1.
