innersalt

The results of dynamic desalination showed the operating capacity of Amphoteric resins was not lower than 201×7 gel resin by stronger absorption acid under the lower regeneration level, they are regenerated easily because of forming innersalt and t.动态脱盐结果表明 ,两性树脂具有强的吸酸作用 ,其工作交换容量不低于 2 0 1× 7强碱树脂 ,由于内盐的形成易于再生 ,可用于常规水处xkp汉语字典

METHOD 1-(2,4-dichloropheny1)-2-(1-imidazoly1)ethanol, the important intermediate of miconazole, was synthesized by epoxidation of 2,4-dichloropheny1aldehyde with sulphonium ylide and by reacting of 2,4-dichloropheny1oxirane with imidazole.方法　以 2 ,4 二氯苯甲醛为原料 ,在碱性条件下与锍内盐反应得到的 1 (2 ,4 二氯苯基 )环氧乙烷与咪唑反应得到抗真菌(yào)物咪康唑中间体 1 (2 ,4 二氯苯基 ) 2 (1 咪唑基 )乙醇。xkp汉语字典

At pH ≤2, amphoteric resins play a role as strong base resins; the absorption of electrolytes takes place according to the anion exchange mechanism, At pH2～7, the molecular sorption by breaking of innersalt bonds increases gradually.主要结果是ｐＨ≤２时，以离子交换为主，ｐＨ２→７时由于内盐键破裂而等当量吸附阴、阳离子作用逐步增强，ｐＨ≥７时则以内盐键破裂而吸附离子为主，在有多种反离子存在时则同时发生离子交换作用，在这种ｐＨ范围的离子选择性显著大于在ｐＨ７以下范围。
