摘　　要：在合成聚合硫酸氯化铝的实验中,发现当盐基度B大于1.23时,有凝胶生成。对同一个配方的反复实验,凝胶的重量不重复,而且相差很大。对不同配方的反复实验同样重复了这个特殊的现象,凝胶的数量与盐基度、各成分的比例毫无关系。初步推断,聚合硫酸氯化铝的分子具有复杂的"构象"的变化,并且构象的变化,影响了分子间的凝聚,造成了实验结果的不能重复。Polymeric sulfuric acid aluminum chloride （PSAC） was synthesized and the gel was formed when the basicity B was greater than 1.23. Repeating experimental results with the same formula showed that the number of gel varied widely. Furthermore, repeating experiments of different formulations, the same phenomenon that no relationship between the number of gel under different basicity and the proportion of each component was observed. It was concluded that PSAC molecules had complex ＂conformation＂ change, which affected the cohesion between molecules, so that irreproducible experimental results were obtained.
