将胶束增溶分光光度法中使用的阳离子表面活性剂长碳链季胺盐,同动物胶在溶液性质上进行比较,发现它们有极为类似的地方:动物胶在酸性溶液中所形成的胶粒,由于H~+过剩而带正电荷;长碳链季胺盐在水溶液中所形成的胶粒(或称胶束)也带有正电荷。因此,它们应都能同亲水性很强的带负电荷的硅酸胶粒(γ-硅酸)相互作用,从而发生凝聚和沉淀。“一切真知都是从直接经验发源的。”我们实验证明,上述推测基本上是正确的。保持盐酸酸度在8N以上时,
The micellar solubilization spectrophotometry used in the long-chain cationic surfactant long-chain quaternary ammonium salt, with the nature of the solution in the gel to compare and found that they have a very similar place: animal glue in the acid solution formed in the glue Tablets, due to H ~ + excess with a positive charge; long chain quaternary ammonium salt in aqueous solution formed by the rubber particles (or micelles) also have a positive charge. Therefore, they should all be able to interact with strongly hydrophilic negatively charged silicate particles (γ-silicic acid) to cause cohesion and precipitation. “All true knowledge comes from direct experience.” Our experiments show that the above conjecture is basically correct. To maintain the acidity of hydrochloric acid above 8N,
