  摘要：

  已经研究了许多聚异丙基苯在25°下的反应，主要是98.4％H 2 SO 4。对-和对-二异丙基苯进行磺化; 没有观察到副反应。1,2,3-三异丙基苯与ClSO 3 H在0° C的CCl 4中产生80％的2,4,6-三异丙基苯磺酰氯和少量的2,4,5-异构体。1,3,5-三异丙基苯与98.4％H 2 SO 4导致形成2,4,6-三异丙基苯磺酸，该酸迅速转化为2,4,5-异构体和3,5-二异丙基苯磺酸。这些化合物的形成比例为0.53±0.05；但是它们在反应混合物中的最终比例为1.0±0.1。1,2,4,5-四异丙基苯与9：1（v / v）98.4％H 2 SO 4 –CF 3 CO 2 H在25°下产生，最初产生相应的四异丙基苯磺酸，但最终产生2,4,5-三异丙基苯。和3，5-二异丙基苯磺酸的比率为6.0±0.6。提出了形成由1,3,5-三-和1,2,4,5-四异丙基苯获得的各种产物的机理。
